Tutor Booking App & Website

I want to build a seamless platform—mobile app (iOS and Android) plus a responsive website—where students can quickly search for qualified tutors, see real-time availability, and confirm a booking in just a few clicks. Core flow is simple: search ➜ compare profiles ➜ select time slot ➜ pay ➜ receive confirmation. Everything on both the web and the app must stay in perfect sync through a single backend.
Key functions I have in mind • Robust search with filters (subject, price, level, location, language). • Individual tutor pages showing bio, credentials, ratings, calendar, and messaging. • Secure booking and in-app payment (Stripe or similar). • Automated notifications and calendar sync for both parties. • Admin dashboard to verify tutors, manage disputes, issue refunds, and pull analytics. Tech is flexible, yet I lean toward a modern stack such as React / React Native or Flutter paired with Node.js, Django, or Laravel and a scalable database (PostgreSQL or MongoDB). Clean, well-documented API endpoints are essential because I plan future integrations. Please attach a detailed project proposal outlining: 1. Architecture and chosen tools 2. Milestone breakdown with timelines 3. Feature list mapped to each milestone 4. Post-launch support plan I will review proposals primarily on clarity of approach, past builds of comparable complexity, and realistic timelines. Strong UI/UX sensibility and secure coding practices are non-negotiable. Skills: PHP, Mobile App Development, Android, Django, Node.js, Laravel, Web Development, React Native

Hands-On Software Architect | Personal Finance App
Applied

/ hr

Wallet Muse is a personal finance application preparing for development. I’m seeking a U.S.-based, hands-on software architect and technical lead with strong production Python experience to establish the technical foundation, guide implementation, and remain involved through ongoing maintenance.
I have wireframes and an existing working calculation model. I’m considering a development firm with Python backend and React Native capabilities for the initial build. Before committing, I want an architect who can independently evaluate the team, help finalize the scope, review implementation, and personally build and maintain critical backend components. This role combines architecture, hands-on engineering, code review, and technical guidance for a nontechnical founder. I communicate directly and prefer clear, candid answers. You should be comfortable explaining decisions in plain English, identifying problems early, and respectfully challenging assumptions. Mutual respect, realistic commitments, and straightforward communication are important. An NDA is required before reviewing private wireframes and detailed specifications or preparing a detailed project estimate. Initial applications should focus on your relevant experience and approach. Sensitive calculation logic will be shared separately with the selected architect when required. We will begin with a defined initial milestone covering requirements review, architecture, evaluation of the proposed development team, and project setup. Its scope, estimated hours, deliverables, and acceptance criteria will be agreed before work starts. Further work will be authorized in phases. Your responsibilities will include: - Reviewing requirements, identifying gaps, and creating a practical implementation plan. - Evaluating whether the proposed development team can deliver the agreed scope. - Recommending and documenting the Python framework, database structure, API contracts, infrastructure, and security approach. - Establishing company-controlled repositories, development environments, automated testing, and deployment foundations. - Personally implementing and maintaining critical backend components. - Reviewing code, coordinating integrations, and checking completed work against agreed requirements and acceptance criteria. - Working with the development team on realistic milestones, dependencies, and delivery expectations. - Ensuring both you and the backend development team can maintain the shared application backend. - Maintaining documentation and providing clear written progress updates. A central requirement is protecting Wallet Muse’s proprietary calculation logic while allowing other developers to build and maintain the surrounding application. You will design and implement a separately controlled, server-side calculation service with a defined API. The application development team should be able to integrate with that API using documentation, test data, and sample responses without receiving the proprietary formulas or implementation. This requires appropriate separation of repositories, deployment permissions, credentials, and infrastructure access, together with authentication, authorization, encryption, and access logging. Developers responsible for the ordinary application backend must not automatically receive access to the private calculation service’s code or administrative controls. The initial milestone should demonstrate this separation using placeholder calculations and the actual developer access roles. Proprietary forecasting functionality will be implemented in a later phase, with implementation access initially limited to the selected architect. Wallet Muse will retain ownership, administrative control, recovery access, and documentation sufficient for an authorized future handover. You should be able to explain the practical limits of these protections, including what can potentially be inferred from calculation results. The preferred technology direction is: - Mobile: React Native/Expo for an online iOS and Android application, with future tablet and web support considered. - Backend: Python. You must have substantial experience personally building, deploying, reviewing, and maintaining production Python applications. - Database and infrastructure: To be finalized with the architect based on the requirements and the development team’s capabilities. Please identify the stack you can personally support. Relevant experience includes relational database design, API development, financial calculations, sensitive user data, restricted-access services, and third-party integrations. Plaid, mobile subscriptions, and translating spreadsheet models into tested software are particularly relevant. You should be comfortable reviewing React Native integration work and coordinating with an external development team, including agreeing on practical meeting overlap across time zones. You will also maintain a complete inventory of third-party libraries, frameworks, SDKs, and direct and transitive dependencies, including versions and licenses. Use automated tooling where practical and update the inventory with releases. Include plain-language explanations of major components and a separate list of external services and recurring costs. Wallet Muse ownership of custom project code and deliverables is required. Code and documentation must remain in Wallet Muse-controlled repositories, with infrastructure and service accounts under company control. Third-party components and licensing requirements must be disclosed. You must personally perform your contracted work. Subcontracting, outsourcing, and delegation are not allowed. Additional personnel from your firm or agency may not contribute to your engagement or access confidential project materials, repositories, or accounts. Collaboration will be with developers or firms engaged directly by Wallet Muse, using individually assigned access. This architect role is an hourly engagement, initially part-time, with potential for a long-term technical relationship. Hours and priorities will be agreed by phase. The development firm’s implementation work would be handled separately through a fixed-price, milestone-based arrangement. Please include: 1. Two relevant projects, explaining your personal responsibilities and what you implemented. Highlight production Python work and any experience separating proprietary logic from systems maintained by other developers. 2. The Python frameworks and backend stack you can personally build, review, deploy, and maintain, plus your experience working with React Native applications. 3. Whether you work independently or are affiliated with a firm or agency. If affiliated, provide its name, your role, approximate number of employees and contractors, and whether you are applying individually or through the agency. 4. Confirmation that you can personally deliver the work, sign an NDA, follow the no-subcontracting requirement, and work within company-controlled repositories and accounts.

FinTech Payments Platform Web & Mobile

I’m building a cloud-based payments platform that lets people and companies create an account, load a balance, and instantly send money to any other user on the system. At launch the core feature is peer-to-peer transfers; paying contacts inside the ecosystem must feel as easy as sending a message. In later phases I may expand to bank payouts or QR / payment-link checkout, so an extensible architecture is important.
Scope • Web app (responsive dashboard) • Native iOS and Android apps with identical flows • Shared REST/GraphQL API, real-time notifications, and an admin console for KYC review, fraud flags, and fee management. Key Flows to Deliver 1. Secure onboarding with email/SMS verification and basic KYC. 2. Multi-currency wallet (at minimum USD) with deposit and withdrawal stubs ready for future integrations. 3. “Send to user” transfer: select contact, enter amount, confirm, instant balance update on both sides. 4. Transaction history, downloadable statements, and in-app receipts. 5. Role-based access so business accounts can add team members and view aggregate activity. 6. PCI-compliant card vaulting and encrypted data at rest. Tech Preferences (flexible if you propose better) • Front-end: React or Next.js for web, Swift/Kotlin or Flutter for mobile. • Back-end: Node.js/TypeScript or Django, PostgreSQL, Redis, Docker, Kubernetes. • Third-party: Stripe Treasury, Circle, or similar for wallet ledgers; Twilio for OTP; AWS or GCP hosting. Acceptance Criteria • All listed flows complete, fully tested, and deployed to a staging environment. • API documentation (Swagger or Postman collection) plus basic CI pipeline. • Source code handed over in Git with commit history. • Apps approved for TestFlight / internal testing on Google Play. Let me know your proposed stack, timeline, and any reference projects that show experience with regulated FinTech or payment rails. I’m ready to move quickly once the technical approach is clear.

About the product
Marujigi is a Korean AI voice companion for seniors aged 70+, paired with a Family app for their adult children and caregivers. Phase 1 (MVP) is in testing: tap-to-talk voice conversation (Naver CLOVA STT/TTS + LLM), SMS-based scam detection, wellness check-ins, and family notifications. Stack: React Native (iOS + Android), Node.js/TypeScript backend, PostgreSQL (Supabase), Firebase FCM, Naver Cloud (Object Storage, CDN, SENS SMS/KakaoTalk), OpenAI API via an LLM adapter layer, Apple/Google in-app subscriptions. Your role: engineer + tech lead The MVP was built by an external contractor. In Phase 2 you will: - Audit the existing codebase, infrastructure and documentation, and deliver a handover/risk assessment within the first 2 weeks - Coordinate the current contractor during the transition (scope, code review, acceptance of deliverables) while taking ownership of the repo, CI and environments - Set up engineering foundations we can hire into: repo structure, coding standards, review process, deployment pipeline, runbooks - Lead the move to in-house development — you'll be our first engineer and will help interview and onboard the next ones as we grow Roadmap — this is a long-term engagement Phase 2 (this contract, 6–24 months) - Feature additions to the existing apps: multiple parents/family members in the Family app, additional family links in the Senior app, voice conversation in the Family app, subscription tiers with per-tier daily turn limits, 7-day free trial, early-bird pricing - B2G / B2B platform (main focus): organization accounts for municipalities and nursing/care facilities — multi-tenant data model, caregiver/admin roles, bulk onboarding of seniors without email, dashboards and periodic reports, per-org configuration, and a web admin console - Locale abstraction: parameterize the Korean implementation so persona prompts, STT/TTS config and content strings load as locale packs (English first) - Hardening: logging, error tracking, test coverage, CI for store builds Phase 2.5 (ongoing after core delivery) - Cognitive games and cognitive-assessment test modules inside the Senior app (platform-policy-safe), capturing measurable signals such as reaction time and response latency alongside voice-based indicators Phase 3 - Integration with a wearable device (LTE smartwatch): location/SOS, step count and heart-rate wellness data, voice conversation from the watch, HealthKit / Health Connect background delivery Who we're looking for - 5+ years full-stack experience with at least 5 shipped React Native apps on both stores - Strong Node.js/TypeScript and PostgreSQL; comfortable owning backend, mobile and a web admin console end to end - You've taken over someone else's production codebase before and can describe how you de-risked it - You've led or coordinated other developers (contractors or a small team) — code review, task breakdown, acceptance criteria - Hands-on experience designing multi-tenant / role-based B2B systems (org → admin → caregiver → end user) - Experience with LLM API integration (OpenAI/Anthropic/Gemini), streaming responses, prompt/config management - Experience with in-app purchases (StoreKit 2 / Google Play Billing) and push notifications - Clear written English; proactive, asynchronous communicator - Bonus: Supabase, Naver Cloud, Korean language, healthcare/eldercare products, BLE or wearable integration How we work - Remote, async-first. Daily written update + 2 short calls/week (KST afternoon / IST morning overlap) - Code in GitHub, tasks on a shared board, decisions documented in writing - Credentials issued via least-privilege sub-accounts and one-time secret links — never pasted in chat - Start with a paid 2-week trial milestone (codebase audit + handover report + one small feature). If it works out, this becomes an ongoing contract covering Phase 2.5 and Phase 3, with a path to a full-time in-house lead role after funding To apply Start your proposal with the word "MARU" and include: 1. Links to 2 React Native apps you shipped (App Store / Play Store) 2. One example where you inherited an existing codebase from another developer or vendor — what did you find, and what did you fix first? 3. One example of a multi-tenant or role-based B2B system you built — how did you model orgs and permissions? 4. One example of an LLM or voice feature you built — what was hard about it? 5. Your availability (hours/week) and earliest start date Generic or AI-written proposals without the above will be skipped.

Cross-Platform Timesheet App

I already have a working Excel timesheet containing dropdowns for our job and item codes. What I need now is a straightforward mobile app that mirrors that sheet, runs on both iPhone/iPad and Android devices, and lets staff complete and submit their weekly timesheets directly from the app—no emailing or file uploads required.
Functionally, each employee should: • open the app, pick the relevant week, • enter their start and finish times for each day, • choose the Job Code, Item Code, add a brief description, and record the hours, • tap “Submit” so the data flows straight to our office for payroll. On my side, I must be able to update or add new codes whenever projects change without pushing a new build; a simple web console or the ability to import an updated CSV/Excel list would be perfect. The app should also retain all the conveniences of the current spreadsheet: dropdown selections, automatic hour totals, and a clean, familiar layout. Ideal deliverables • Android APK + iOS TestFlight build ready for employee rollout • Source code (React Native, Flutter, Power Apps—open to suggestions) • Simple admin guide showing how to update the code lists and access submitted data If you have experience turning Excel sheets into intuitive cross-platform apps and can keep future maintenance simple for a non-technical admin, I’d love to hear how you would tackle this.

The core gameplay would be: Choose a country → choose a dish → prepare ingredients → cook through interactive mini-games → plate the food → serve customers → earn stars/coins → upgrade the restaurant → unlock the next country. I want the game to have a colorful, polished style similar to the visual concept I sent. For the initial version, I would like to start with 5 countries and approximately 15 dishes: 🇭🇹 Haiti — Griot, Diri Kole, Soup Joumou 🇯🇵 Japan — Sushi, Ramen, Chicken Katsu 🇮🇹 Italy — Pizza, Pasta, Tiramisu 🇲🇽 Mexico — Tacos, Enchiladas, Churros 🇫🇷 France — Crêpes, Croissants, Ratatouille I want a world map where players unlock countries as they progress. The cooking should involve interactive actions such as chopping, mixing, seasoning, cooking, plating and serving customers rather than simply pressing a “cook” button. Players should earn stars and coins and be able to upgrade their restaurant and eventually customize their character. The long-term concept is much larger. I want the game to eventually expand into regional editions such as Taste the Map: Caribbean, Africa, Europe, Asia, North America and South America, with additional countries and recipes added through updates. I want to start with the Caribbean version first I am also developing Taste the Map as a larger food brand that could eventually include spices, cookware, cookbooks and cooking videos, so I want the game branding and architecture to allow for future expansion. Could you please tell me what would be included in your $5,000–$8,000 custom-game package for a project like this? Specifically, I would like to know: 1. How many countries/levels would be included? 2. How many cooking mechanics? 3. Would you create the character and animations? 4. Would the world map be included? 5. Would restaurant upgrades be included? 6. Would iOS and Android both be included? 7. Would advertisements and in-app purchases be included? 8. Would you handle App Store and Google Play submission? 9. Would I receive the complete source code? 10. Would I retain ownership of the game and intellectual property? 11. How long would development take? 12. Can the project be divided into milestones? I would also like to know whether you have previously developed cooking, restaurant, simulation or time-management games. I can provide the complete game concept document and additional visual references.

Buscamos a un desarrollador o equipo para construir el motor de recomendación de una app móvil de películas y una interfaz básica para probarlo con usuarios. Ya tenemos el diseño de referencia: necesitamos a alguien que lo implemente, no que lo diseñe.
1. Algoritmo de recomendación (parte principal) Perfil de gusto por usuario. Se construye con señales explícitas («me interesa», «para otro momento», «ya la vi») y señales diferidas (feedback días después de ver una película). Recomendación por contenido. Usa embeddings semánticos de sinopsis y metadatos (tono, ritmo, estructura narrativa), no solo género, con búsqueda por similitud vectorial. Filtros combinables. Estado de ánimo (mood), género, director, época y duración. Explicabilidad. Cada recomendación devuelve un porcentaje de afinidad y una razón breve. Exclusiones. No vuelve a proponer lo ya visto ni lo descartado. Disponibilidad. Consulta en qué plataformas está la película en Colombia, mediante una API de catálogo (TMDB, JustWatch o Watchmode). 2. Backend API REST documentada con autenticación básica (correo, Google o Apple). Base de datos con soporte vectorial (por ejemplo PostgreSQL con pgvector). Registro de eventos de uso para medir y ajustar el algoritmo. 3. Interfaz básica (móvil o web responsive) Onboarding corto: elegir moods y algunas películas de arranque. Pantalla de recomendación con película, afinidad y razón. Acciones con gestos (deslizar) y botones de respaldo. Filtros y perfil con historial de películas vistas. No necesita pulido visual avanzado, pero sí funcionar de punta a punta con datos reales. Fuera de alcance: pagos, publicidad, funciones sociales, notificaciones push y publicación en tiendas de apps. Entregables Código en repositorio Git, con README e instrucciones de despliegue. API documentada (Swagger u OpenAPI). Documento breve que explique cómo funciona el algoritmo y cómo ajustarlo. Evaluación básica del algoritmo (métricas sobre un set de prueba). Despliegue en un entorno de pruebas. Stack: abierto. Proponer lo que dominen. Lo ideal es Python o Node en el backend y React Native, Flutter o web en el front. Habilidades deseadas: sistemas de recomendación, embeddings y NLP, bases de datos vectoriales, desarrollo de APIs y desarrollo móvil o web. Qué pedimos en su propuesta Precio total, con desglose entre algoritmo, backend e interfaz. Tiempo estimado e hitos. Stack propuesto. Proyectos similares. Preguntas o riesgos que vean en el alcance. Skills: Python, Graphic Design, Logo Design, Photoshop, Android, Machine Learning (ML), API Development, Natural Language Processing

Manual QA Tester for a Mobile-First Web App (iPhone + Android), Ongoing Partnership

Hi! I'm building Crato (crato.store), a simple online store for Instagram and TikTok creators. Creators sell guides, templates, courses, calls and merch, and their buyers pay straight to the creator's own Stripe.
I'm looking for a careful manual QA tester with a great eye for design, for an ongoing partnership, before and after our launch. If it works well, I want to keep working with the same person long term. WHAT YOU'LL DO - Test new designs and features on a real iPhone and a real Android phone - Test inside the in-app browsers of Instagram, TikTok, Threads and other social apps, since that's where most of our buyers open links - Review new designs and give honest, constructive feedback: what's confusing, what feels slow, what looks off, and how it could be better - Send all feedback, bugs and design notes, through simple GitHub forms I'll set up for you: steps, what you expected, what happened, plus screenshots or a screen recording HOW WE WORK - Testing happens in live sessions on a call with me (Google Meet or Zoom) while you share your phone screen - Sessions follow our cycles. During development: short sessions whenever a new design or feature is ready. Before each launch: longer sessions for a full test of the whole platform. - We schedule every session together - Before most sessions I'll share a full test guide, so you can prepare ahead of time and the call is easy to follow - You'll use test accounts and test cards only. Nothing real is bought. - A short NDA before you see unreleased designs YOU MUST HAVE - A real iPhone and a real Android phone (please tell me both models) - Instagram, TikTok and Threads installed and used often - A strong design sense: you notice colour, fonts, spacing and layout, and you can explain why something works or doesn't - Constructive criticism: you point out problems clearly and suggest a better way, not just "I don't like it" - Good written English and clear, short reports - Experience in manual testing of web or mobile apps - Basic GitHub Issues skills are a plus. We use simple forms, so it's easy to learn RATE $5 to $10 per hour, depending on experience. We start with a paid 2-hour trial. TO APPLY: A 5-MINUTE TEST (required) Open crato.store on your phone, ideally from inside Instagram, TikTok or Threads. Look around for 5 minutes. Please browse only: don't sign up, don't buy, and don't create a store. The "Try it" box on the homepage is fine to use, it saves nothing. Then send me just 3 short points: 1. One problem or confusing thing: where it was and why it matters 2. One design note: colour, font, spacing or layout, and how you'd make it better. Strong, specific design feedback gets extra points. 3. One thing you liked Add your phone model, the app you opened it from, and one screenshot from your own phone. Start your proposal with the word "Thumb" so I know you read this far. Applications without the 5-minute test won't be considered. Client's questions:

.SOCIAL MEDIA & COMMUNITY MANAGER (+ PAID ADS) – ATLANTA, GA
Turn real Pros and real jobs into the content that recruits the next Pro and wins the next customer. This is a builder role, not a maintain-the-calendar role. THE SHORT VERSION Afrihelps grows on trust first; ads amplify what’s already working. You’ll be in the community where customers and Pros actually live: filming, posting, replying and showing up at events, not posting at it from outside. ABOUT AFRIHELPS Afrihelps (afrihelps.com + iPhone/Android apps) connects customers with trusted African and diaspora professionals: caterers, braiders, tailors, photographers and more, starting in Atlanta. Every Pro is ID-verified, and Pros never pay for leads or commission. Atlanta Pros who join free before December 31, 2026 become Founding Pros. That promise is the job. Big platforms charge Pros per lead. We don’t, so every spotlight, review and referral has to prove that a trusted local Pro, vouched for by neighbors, is worth choosing. WHY THIS ROLE, WHY NOW Our customers and Pros live in the same churches, cultural associations, WhatsApp groups and celebrations. Distribution is community. At this stage, social media and community management are one job: the person creating the content is also the person Pros and customers talk to, see at events, and trust. WHAT YOU WILL OWN Social channels end to end: TikTok, Instagram and Facebook. Plan, shoot, edit and post short-form video and stories. Pro spotlights: film with Pros, turn their work into content, and use it to recruit more Pros, including the Founding Pro push. Community: WhatsApp groups, comments and DMs, with fast, human replies. Events: cover community gatherings, church and association events, and celebrations (with permission) and turn them into content. Reviews and referrals: prompt customers after jobs, turn photo reviews into Neighbor Proof posts, keep the referral loop spinning. Paid ads: plan, launch and manage small-budget Meta (Facebook/Instagram) and TikTok ads that put our best Pro spotlights and Neighbor Proof posts in front of Atlanta Pros and customers. Set up tracking, test creatives and audiences, and report cost per sign-up and quote request. Weekly reporting: what worked, the numbers, and next week’s plan, every week, in writing. FOUR CONTENT PILLARS Meet Your Pro: a verified Pro as a person: their craft, story, and how to book them. Before/After: the transformation (braids, tailoring, catering, photography) with the Pro credited. Ask 3 Pros: demo the core flow: ask three Pros at once, free, and compare real replies. Neighbor Proof: real reviews with photos from real local customers. WHO YOU ARE You live in, or are deeply connected to, metro Atlanta’s African diaspora community. Proven short-form video skills. Show us your TikTok or Reels, not just a resume. Comfortable on camera and filming others; you can tell a story in 30 seconds. A self-starter who can build a content system from scratch. Hands-on experience running Meta and/or TikTok ads with small budgets. Tell us what you spent and what it delivered. BONUS POINTS You speak Yoruba, Igbo, Twi, Hausa or another African language. You’ve grown a marketplace or community brand before. You’re handy with CapCut and Canva. HOW SUCCESS IS MEASURED (30-60-90) Days 1–30: know the platform and top 20 Pros by name; content system live; 12+ posts; 5 Pro spotlights; community map (20 WhatsApp groups, 10 congregations, 8 associations + events calendar); baseline metrics. Days 31–60: 4–5 posts/week + daily stories; holiday campaign live (Thanksgiving–Christmas); 3+ events covered; 25+ Neighbor Proof posts; first ad tests live on top-performing organic content; first monthly report. Days 61–90: documented weekly playbook; 2+ community partnerships co-producing content; review and referral engine running; content- and ad-attributed sign-ups and quote requests tracked, with cost per sign-up; 90-day report and next-quarter plan. Full scorecard attached. DETAILS Location: Metro Atlanta. In person for events and Pro shoots, remote otherwise. Atlanta residents only. Type: Part-time Pay: [$20 - $30hr] Ad budget: separate from your pay, approved by the CEO Reports to: Owner/CEO TO APPLY, answer the screening questions and include: Links to 2–3 TikTok or Reels you filmed and edited One ad campaign you ran: budget, goal and results Which part of metro Atlanta you live in, and your connection to the African diaspora community there Thank you!

Higher Powers builds guided therapeutic experiences you can do at home. The product is the experience itself: composer-scored sessions with spoken word guidance, delivered through our own app, with medical screening and physician oversight handled by licensed clinical partners. We are pre-seed funded and launching in Florida in early 2027, with more states to follow.
THE ROLE You will be the engineer who builds the app. Not a contributor on a team. The person. We have a finished technical spec and a fractional CTO. We do not have a line of production code. You will take the spec, pressure-test it, and ship V1 over the next six months. After launch you keep building. The second half of the job is compliance. Everything you build handles protected health information. You own the technical side of HIPAA: the PHI boundary, encryption, audit logging, access control, vendor BAAs, and the security risk assessment. Our attorneys handle the paper. You handle the systems. WHAT YOU WILL BUILD - Flutter for iOS, Android, and web from one codebase - Node.js / NestJS backend, PostgreSQL, managed cloud infrastructure on Google Cloud (GCP) - Passwordless auth with magic links and device biometrics - Embedded telehealth video with call recording into our own storage - Web-only purchasing behind a processor-agnostic payment layer - Video delivery with in-app progress tracking inside our PHI boundary - HealthKit and Health Connect biometric capture - An AI support layer with clinical guardrails and crisis escalation - Integrations with clinical systems (EHR, e-prescribing, PDMP) through APIs WHAT WE NEED FROM YOU - 6+ years building production software, with at least one product shipped end to end where you were the primary engineer - You have built or operated a HIPAA-regulated system and can explain, in detail, how you kept PHI out of logs, analytics, and third-party tools - Flutter and Dart in production, not a side project - Node.js with TypeScript, PostgreSQL, and a major cloud platform (GCP preferred) - Payment integrations and at least one video or real-time SDK - Comfortable being the only engineer: you write the code, the tests, the infrastructure, and the runbook - Clear written English. Most of our communication is async and in writing. NICE TO HAVE - Healthcare API integrations (FHIR, e-prescribing, EHR vendors) - Telehealth or payments experience - App store submission experience HOW WE WORK You report to the CTO day to day and work with the CEO. The team is eight people across the US and Puerto Rico. Remote, any time zone with 4+ hours of overlap with US Eastern. Puerto Rico based candidates are preferred, and we are open to candidates across Central and South America. Client's questions:

Our Android app is currently live on Google Play, and we're continuing development on our website, iOS app, and Educational Portal. We need someone who can independently test the platform, identify bugs, and help us make sure everything works properly before we expand further. What we need tested: - Android and iOS mobile applications - Website functionality and navigation - User registration, login, and account management - Basic and Premium subscriptions, including payments and restoring purchases - Stock search, watchlists, charts, and market information - Portfolio Optimizer and Stock Evaluator - Educational Portal, including lessons, quizzes, XP, badges, and progress tracking - Mr. Finley, our AI financial education assistant - Incorrect data, placeholder information, broken features, and display issues - General usability across different devices and screen sizes We're looking for someone who will thoroughly test the platform from a user's perspective, not just check whether buttons work. What we expect: We need clear bug reports that explain what went wrong, how to reproduce the issue, and what should happen instead. Screenshots or short screen recordings should be included when helpful. You'll also need to identify which issues are most serious and retest features after our developers make corrections. Who we're looking for: You should have experience with manual QA testing for websites and mobile apps. Experience with fintech, investment platforms, or subscription-based applications is a plus. We have developers working on different parts of the platform, so good communication and the ability to work independently are important. This position is focused on functional testing and user experience. Backend API testing and security penetration testing are not required. Project Details: We'd like to begin with approximately 20–30 hours of testing, with the possibility of additional work as new features are completed. When applying, please tell us about your QA experience, similar projects you've tested, which devices you use, your hourly rate, and when you can start. We're looking for someone dependable, detail-oriented, and comfortable identifying problems and communicating them clearly.

I’m building a mobile app that helps devoted Tesla, SpaceX, and general AI enthusiasts go beyond headline news and truly learn. The idea is simple: a clean, intuitive platform that streams high-quality videos and embeds interactive lessons so users can explore rocket launches, Autopilot updates, and cutting-edge AI research in one place.
Here’s what I need from you: • A cross-platform app (iOS and Android) that plays curated video content smoothly and lets users engage with interactive elements—think swipe-through explainers, tap-to-reveal diagrams, or quick in-video Q&A. • A lightweight backend or CMS where I can upload fresh footage or lesson modules the moment new material drops, keeping fans in the loop without code changes. • Push-notification handling so users know instantly when a Starship test fires, a new FSD beta releases, or an AI breakthrough is announced. • Source code, build files, and a concise admin guide so I can maintain and expand the library myself. If you’ve worked with video streaming, React Native or Flutter, Firebase, or similar stacks, you’ll feel right at home. All assets and content outlines are ready on my side; what I’m missing is the technical expertise to bring them together into a polished, engaging experience. Let’s give the fan community a learning tool they can’t put down. Skills: PHP, Mobile App Development, iPhone, Android, Backend Development, React Native, Flutter, Video Streaming

Se requiere una interfaz UX/UI intuitiva, visualmente atractiva y optimizada para dispositivos móviles, con infraestructura cloud, almacenamiento seguro de datos, integración de servicios externos y una arquitectura modular que permita incorporar nuevas funcionalidades progresivamente. Buscamos profesionales con experiencia en plataformas tipo marketplace, sistemas de reservas, integraciones API y desarrollo de aplicaciones escalables. Se requiere el desarrollo de un módulo de experiencias digitales inmersivas e interactivas, integrado a la plataforma principal, con capacidad de reproducción y sincronización de contenido multimedia (audio, imágenes, animaciones y recursos interactivos). El sistema deberá contar con infraestructura de almacenamiento en la nube (AWS S3, Google Cloud Storage o Firebase Storage), distribución de contenido mediante CDN y tecnologías de streaming para optimizar la carga y reproducción de archivos. Se contempla la implementación de motores de interacción basados en eventos, secuencias dinámicas y mecánicas de gamificación mediante tecnologías como HTML5, WebGL, Three.js o motores compatibles con entornos web. Adicionalmente, se requiere integración con APIs de respuesta háptica (Vibration API o funcionalidades nativas según compatibilidad del dispositivo), Web Audio API para procesamiento y sincronización de sonido, y sistemas de seguimiento del progreso e interacción del usuario. La arquitectura deberá permitir la administración de contenidos desde un CMS, la ejecución de experiencias interactivas sin instalaciones adicionales y la incorporación progresiva de nuevos módulos, garantizando compatibilidad multidispositivo, rendimiento, escalabilidad y una experiencia fluida.
