Estamos buscando un administrador de sistemas o ingeniero DevOps con experiencia específica en la plataforma Survey Solutions del Banco Mundial para realizar la instalación y configuración completa de nuestro propio servidor de recolección de datos (CAPI/CAWI).
Nuestra agencia opera desde equipos Mac, por lo que necesitamos un entorno basado en la nube que sea accesible y administrable vía web de forma segura. El objetivo es migrar nuestras operaciones actuales hacia esta infraestructura de código abierto.
Responsabilidades y Alcance:
Configuración del VPS: Aprovisionamiento de un servidor virtual (ej. DigitalOcean, AWS o Azure) con los requisitos técnicos adecuados.
Instalación vía Docker: Despliegue de Survey Solutions utilizando el método de contenedores Docker (PostgreSQL, HQ Application, NGINX).
Seguridad y SSL: Configuración de certificados SSL (Let’s Encrypt/Certbot) para garantizar acceso seguro vía HTTPS.
Configuración de Base de Datos: Instalación y optimización de PostgreSQL.
Ajustes de la Aplicación:
Configuración de BaseURL y puertos.
Habilitación de parámetros para Audio Audit (grabación de entrevistas para auditoría).
Configuración de reCAPTCHA para encuestas web (CAWI).
Configuración de Audio Audit
Integración de Google Maps API para georreferenciación.

Requisitos:
Idioma: Se aprecia Fluidez en Español para la comunicación y entrega de instrucciones de mantenimiento.
Experiencia demostrable instalando y manteniendo servidores de Survey Solutions.

Una breve guía de referencia (en español) sobre cómo reiniciar servicios y realizar backups de la base de datos.
En mi empresa, llevamos dos años impulsando la implantación de ODOO como nuestro ERP en colaboración con una empresa local, pero el desarrollo es lento y con riesgo de quedar inacabado. Busco a un especialista que tome el proyecto donde está y lo lleve hasta la puesta en producción.
Alcance principal
• Ventas y CRM: necesito que los módulos queden totalmente operativos.
· Gestión de rutas: Acabar el módulo ya iniciado para gestionar las rutas. Otra opción sería la de vinvular una aplicación a través de la API y disopner de esa funcionalidad fuera.
• Personalización e integración: habrá que adaptar pantallas, flujos y reports a nuestro proceso comercial e integrar ODOO con los sistemas externos que ya usamos (contabilidad y gestión administrativa).
· Disponemos de un asistente virtual conectado a la BBDD de Odoo, que no requeriría demasiado para que sea definitiavamente operativo.
Funciones clave a habilitar
– Gestión de clientes potenciales con filtros y alertas.
– Automatización de ventas: tareas, recordatorios y reglas de asignación.
– Seguimiento de oportunidades de negocio con embudos claros y pronósticos.
– Vinculación con la parte administrativa-contable para que la información fluya sin duplicidad.
Qué espero del trabajo
1. Auditoría rápida del código y la configuración existentes.
2. Plan de acción detallado con tiempos realistas.
3. Desarrollo de personalizaciones y pruebas unitarias.
4. Integración con los sistemas externos definidos.
5. Migración de datos pendientes, capacitación breve al equipo y acompañamiento hasta el arranque estable.
6. Posibilidad de absober el desarrollo en su totalidad e incorporarlo en nuevos servidores independentemente de la empresa original
Trabajo en remoto; acceso a repositorio y servidor de pruebas disponible desde el primer día. Valoraría experiencia demostrable con proyectos similares y buenas prácticas de documentación para que el mantenimiento futuro sea sencillo.

I’m building a focused SaaS application designed to help trade businesses finish completed jobs cleanly by delivering a structured, client-facing handover.
This product is intentionally narrow in scope and is not:
- A job management system
- A CRM
- A quoting, invoicing, or scheduling tool
It exists only to handle the final step of a job.
---
Core Use Case (High Level)
After a job is completed, a trade needs to:
- Deliver manuals, certificates, plans, and photos
- Clearly list installed equipment
- Share credentials safely (when required)
- Provide clients with permanent access to handover information
- Record that the client has acknowledged receipt
The product creates a single, calm portal where this information lives.
---
Functional Requirements (v1)
Account & Workspace
- Email/password authentication
- One company workspace per account
- Basic company settings (name, branding)
Project-Based Handover
- Create a project per completed job
- Projects have a simple lifecycle:
- Draft
- Sent
- Acknowledged
- Each project stores all handover information in one place
Equipment Entries (Reusable)
- Ability to add equipment to a project
- Equipment fields include:
- Name / description
- Optional notes
- Optional attached files
- Equipment can be saved for reuse across future projects
- Editing saved equipment must not affect historical projects
(This is intentionally simple — no inventory, automation, or logic)
File & Credential Handling
- Upload files per project:
- Manuals
- Certificates
- Plans
- Photos
- Store credentials per project item:
- Username
- Password
- Notes
- Toggle visibility:
- Internal only
- Shared with client
Client-Facing Portal
- Each project generates a read-only public portal
- No client login required
- Mobile-friendly
- Portal includes:
- Project overview
- Equipment list
- Files
- Shared credentials
- Client acknowledgment:
- Name entry
- Confirmation action
- Timestamp recorded
Completion State
- Once acknowledged:
- Project is considered complete
- No ongoing engagement required
- The product should feel finished at this point
---
Lightweight Marketing Site
- Simple public site (1–2 pages)
- Purpose:
- Explain the problem
- Explain the solution
- Display pricing
- No CMS
- No SEO
- No blog or funnel
- Copy and direction will be supplied
---
Non-Goals (Out of Scope for v1)
- Job tracking
- Scheduling or dispatch
- Invoicing or payments
- Analytics or dashboards
- Integrations with third-party job systems
- Advanced permissions or roles
---
Project State
- Clear written build brief exists
- Working prototype available for reference
- Product constraints are defined
- This is implementation, not product discovery
---
Tech Expectations
Preferred stack (open to discussion):
- Modern React framework (Next.js preferred)
- TypeScript
- Relational database (Postgres or equivalent)
- Managed authentication and file storage
- Clean, maintainable codebase
---
Budget & Delivery
- Fixed-price project
- Budget: $3,000 USD
- Milestone-based delivery
- Potential follow-on work after v1 launch

Despite multiple messages and follow-ups, communication was completely absent. In remote work, responsiveness is essential, and a simple acknowledgment would have gone a long way. I also completed a significant amount of work without receiving any payment. I worked hard on the eBooks he asked me to create and dedicated a lot of time to every project. That payment was meant to support my mom’s cancer treatment. As someone who works hard to earn an honest living, it’s disheartening when that integrity isn’t respected. I would not recommend working with this client based on my experience.

We are looking for a Senior AWS Backend Developer to investigate and resolve stability issues on our serverless education platform.
The Symptoms:
* Intermittent Errors: We are experiencing random 500 Internal Server Errors on specific features (e.g., Search, blog pages ), while other parts of the site work fine.
* Environment Confusion: There seems to be a mismatch in our setup; production traffic appears to be generating logs in the wrong environment (Dev vs. Prod), or logs are missing entirely for the live site.
* Deployment Issues: Recent updates to environment variables (like DB credentials) do not seem to be reflecting on the live production site immediately.
Scope of Work:
1. Diagnose Root Cause: Audit the AWS Lambda, API Gateway, and Alias configurations to understand why traffic routing and logging are behaving inconsistently.
2. Fix Connectivity: Resolve the database connection failures and ensure the production environment is stable and communicating with the correct resources.
3. Correct the Configuration: Ensure that Production and Development environments are properly isolated and that deployments update the live site correctly.
Tech Stack:
* AWS Lambda (Node.js/Express)
* AWS API Gateway
* PostgreSQL (RDS) with Sequelize ORM

We’re building a web platform that lets users take photos of real rooms and see photorealistic visualizations of products placed inside those spaces using modern image generation.
This is a core product experience, not a demo. The output quality matters, the UX matters, and the system needs to scale to real users.
We’re hiring a full-stack engineer to own delivery of this experience end-to-end, embedded directly with our internal engineering team.
You'll be asked to deliver:
- User-driven image generation flows
- Photorealistic room visualizations using Google's Nano Banana
- Backend services to manage generation jobs, prompts, inputs, outputs, and metadata
- The database to store this data
- Frontend experiences for browsing, regenerating, and comparing generated images
This is an engineering-heavy role - you’ll be designing systems, not just wiring up APIs.
*We care less about years of experience and more about proof you've built something real using LLMs or image generation.*
You should have:
- Demonstrable experience using LLMs or image generation APIs in a real project
- Comfort owning features end-to-end (backend, frontend, data model)
- Strong TypeScript fundamentals
- Solid product instincts (you can reason about UX, not just code)
- Experience shipping production features, not just prototypes
Client's questions:
Links to projects where you used LLMs or image generation
A short description of something you personally built using image gen or LLMs, the problem it solved, and what you learned
Give a brief summary of relevant fullstack experience
Include a link to your GitHub profile and/or website

Bond Studio makes software that lets users capture their space with their phone and see a visualization of how that room could look if it were remodeled. Users can browse products, select them, and see them visualized in their space.
Part of this experience is search where users can type in queries and see products based on their query. Currently this functionality is powered by a custom Python service that contains an index of all of our products and leverages LLMs to provide results to users.
Search quality and speed are critical to the overall user experience.
We have a comprehensive benchmark for this service and are looking to work with a software engineer to improve its performance on this benchmark.
This is not a greenfield project. You will be working with an existing production system and are expected to diagnose bottlenecks, propose improvements, and implement measurable gains.
You will analyze and improve a real-world product search system that includes:
A large, structured product catalog with many attributes and variants.
User-driven filtering and refinement (dimensions, style, finish, price, etc.).
Natural-language queries interpreted by an LLM-backed layer.
A backend search service that must be fast, stable, and scalable.
The focus of this engagement is on result quality while maintaining acceptable performance.
Client's questions:
Describe a production search system you’ve worked on or owned.
How do you approach improving result relevance when users say "the results don’t feel right" but there’s no obvious bug?
Describe a time you joined an existing codebase and had to make impactful changes quickly.
Have you worked with semantic or vector-based search, or search systems involving LLMs?

I am looking for a Senior Full Stack Developer to develop a platform for statistical analysis and game history at betting houses, replicating the features of the Tipminer website.
Exact reference: https://www.tipminer.com/en
What needs to be done:
Real-Time Monitoring (Core):
Create a system (Scraper/Sniffer) capable of reading game results on our platform via WebSocket or API Reverse Engineering.
The data must arrive on the dashboard with zero latency (as soon as the round ends).
Anti-blocking system (circumvent Cloudflare/Protections) to ensure stability.
Frontend (Dashboard):
Responsive layout (Mobile and Desktop) similar to the reference.
Candlestick history grid with conditional coloring (Blue, Purple, Pink).
Statistical graphs of accuracy, patterns, and paying times.
Backend & Database:
Store complete round history.
Automatic calculation of strategies (e.g., candlestick patterns, sequences, gale).
Mandatory Technical Requirements:
Backend: Node.js, Python, or Go.
Frontend: React, Vue.js, or Next.js.
Connection: Advanced experience with WebSockets (WSS) and network sniffing.
Database: PostgreSQL or MongoDB.
Deliverables:
Complete source code (Frontend + Backend).
Installation and configuration on the server (VPS).
Basic documentation on how to add new “houses” in the future (if applicable).
Attention Candidates: Do not send generic proposals. This project requires knowledge of intercepting WebSocket traffic from iGaming sites. If you already have experience with casino APIs or similar projects (Tipminer, Tiphunter), mention this at the top of your proposal.
Mandatory questions for the proposal:
Do you have experience capturing data via WebSocket (WSS) from protected websites?
What stack/technology will you use to ensure minimal delay?
Do you have a portfolio of projects related to iGaming or real-time dashboards?
What stack/technology will you use to ensure minimal delay?
Do you have a portfolio of projects related to iGaming or real-time dashboards?
We are building HoroLedger, a "Carfax for Luxury Watches." It is a centralized, dealer-verified registry that tracks a timepiece’s technical health and ownership lifecycle.
We have a complete, dev-ready specification package (including database schema, API requirements, and logic flows) and high-fidelity HTML/JS interactive prototypes for the UI. We need a skilled developer or agency to turn these specifications into a production-ready MVP.
The Core Challenge: This is a "Zero-Knowledge" system. We store technical watch data, but we never store owner PII (Personal Identifiable Information). The architecture must reflect this strict separation.
Scope of Work (MVP 1.0)
You will be building three core modules based on provided prototypes:
Dealer Management Portal (Frontend & Logic):
Authentication & Vetting flow.
Intake Engine with cascading dropdowns (Brand - Model - Ref).
Technical Vitals input (Amplitude, Beat Error) with auto-color coding telemetry.
Integration with simulated DMS (Dealer Management System) APIs.
The Universal Ledger (Backend):
Collision Detection Engine: Custom logic to flag if a serial number is logged in two locations simultaneously.
Market Intelligence: Fetching and storing valuation snapshots at the time of entry.
Database: Setup PostgreSQL (User data) + Firestore/NoSQL (Immutable Service Ledger).
Consumer Verification Portal (Public Output):
Public serial number search.
"Blurred" preview of records.
Stripe Integration: Pay-gate to unlock the full PDF report.
Dynamic PDF Generation: Generating a high-fidelity "Certificate of Provenance" (LaTeX/HTML to PDF) upon payment.
Tech Stack Requirements
Frontend: React.js / Next.js (Must use Tailwind CSS).

About Us
Mandarin Blueprint is an immersive Chinese language learning platform and community. Our mission is to help learners make significant progress in Mandarin fluency using our innovative and proven methods.

Role Overview
As a key member of the MB Elite development team, you will lead the migration of an existing Mandarin learning web application from Flask to FastAPI. Your main responsibility is to ensure a smooth framework transition while preserving full feature parity, performance, and reliability.
You will work deeply on backend architecture, converting Flask blueprints into FastAPI routers, modernizing authentication flows, and maintaining a stable REST API layer. The platform relies on Supabase (PostgreSQL) for data storage, includes JWT based authentication, course and content management, spaced repetition learning logic, chatbot features using OpenAI, and progressive web app capabilities.
The ideal candidate is a hands-on Python developer with strong FastAPI experience, confidence reading Flask codebases, and a careful, methodical approach to migrations. You should be comfortable working independently, communicating clearly in a remote environment, and writing clean, maintainable code as the system evolves.
This role offers the opportunity to own a meaningful backend modernization project for a learning platform, and to help shape future development after the migration is complete.
Responsibilities
- Migrate the current Flask backend to FastAPI as the primary deliverable.
- Convert Flask blueprints into FastAPI routers and reorganize the backend structure cleanly.
- Maintain and enhance backend functionality during and after migration.
- Migrate session based authentication to FastAPI compatible flows.
- Design, develop, and maintain RESTful API endpoints for both public and authenticated users.
- Implement and secure JWT authentication, authorization, and session management.
- Work with Supabase (PostgreSQL) for database queries, schema handling, and performance.
- Integrate third party APIs, including OpenAI for chatbot features.
- Ensure complete feature parity across all modules, including:
User authentication and registration
Invitation code management
Course and content management
Character and sentence learning modules
Review system and spaced repetition logic
Account and settings management
Public API endpoints
PWA related backend support
- Debug, test, and fix issues across the application.
- Write clean, maintainable, scalable code following best practices.
Must-Have Qualifications
- Language Proficiency: Native or professional fluency in English and Mandarin Chinese (HSK 5 or 6 certification required).
- Strong hands-on experience with FastAPI, including production level use.
- Solid working knowledge of Flask to interpret and migrate the existing codebase.
- Strong Python skills (3.9+), including async and modern backend patterns.
- Proven experience designing and maintaining REST APIs.
- Prior experience migrating Flask to FastAPI or similar backend migrations.
- Experience with Supabase or PostgreSQL based backends.
- Practical knowledge of JWT auth and secure session handling.
- Familiarity with Git workflows and version control.
- Strong debugging ability, attention to detail, and backend security awareness.
Nice-to-Have Qualifications (Preferred Skills)
- Experience building or supporting PWAs.
- OpenAI API integration experience.
- Familiarity with spaced repetition systems, learning algorithms, or EdTech apps.
- Comfort working with Jinja2 templating and TailwindCSS.
- Experience with Gunicorn deployments and production tuning.
- Strong async and await understanding in Python, performance tuning in FastAPI.
Compensation Structure
- Hourly Rate: USD $25–$40 per hour, depending on experience and skill level.
- Working Hours: Approximately 30 to 40 hours per week.
- Time Zone Overlap: Candidates must have at least 3 to 4 hours of daily overlap with China Standard Time (UTC+8) to enable effective collaboration with the core team.
- Work Environment: Fully remote with flexibility and opportunities for long-term growth in a dynamic, collaborative environment.
Why Join Us?
Opportunity to work with a fast-growing, community-driven educational platform.
A flexible, remote role with room for growth and expansion of responsibilities.
A collaborative and supportive team that values innovation and efficiency.
How to Apply
If you are interested in applying for this role, please send us a 5-minute (max) Loom video addressing the following:
Describe your experience migrating or refactoring Flask apps into FastAPI. Please provide a link to your GitHub or portfolio and walk us through one specific FastAPI project you owned.
This role requires HSK 5-6 proficiency. Please describe your fluency level in English and Mandarin. How has your bilingualism helped you in previous technical roles or while reading localized code?
Describe your experience with JWT authentication, session management, and working with Supabase or PostgreSQL. How would you approach migrating a Flask session based auth system into FastAPI securely?
What process do you follow to ensure full feature parity during migration, avoid regressions, and keep the app stable for users while changes roll out?

Voglio realizzare una piattaforma di scommesse dedicata ai Giochi virtuali con un focus iniziale sul calcio virtuale. Il sito dovrà offrire un’esperienza utente fluida e moderna, ispirata al look‐and‐feel di bet365, e garantire la stessa stabilità e velocità viste su goldbet.it.
Funzionalità online
• Front-end responsive in stile bet365 con calendario eventi, statistiche live, slip di scommessa dinamico e risultati in tempo reale.
• Motore di quote per il calcio virtuale, schedulazione automatica dei match, gestione mercati e payout.
• Pannello admin completo per configurare eventi, quote, promozioni, utenti, limiti di giocata e reportistica.
• Modulo pagamenti (deposito/prelievo) con wallet interno e storico transazioni.
• Log di sicurezza, gestione KYC e controllo frodi.
Gestione centro scommesse fisico
• Integrazione in tempo reale tra sito e sala scommesse.
• Terminali di scommessa self-service collegati al sistema centrale per stampa ticket e verifica vincite.
• Sistema di cassa con apertura/chiusura turni, gestione contante, rendicontazione e sincronizzazione con le giocate online.
Requisiti tecnici
• Codice scalabile (PHP/Laravel, Node.js o stack equivalente) e database performante (MySQL/PostgreSQL).
• API REST/JSON per terminali e eventuali app mobile.
• Interfaccia modulare in modo da poter aggiungere futuri giochi virtuali (ippica, automobilismo, ecc.) senza rifattorizzazioni pesanti.
Consegna
1. Prototipo UX/UI approvato.
2. Sviluppo back-end e admin panel totalmente funzionante.
3. Setup di almeno un terminale fisico collegato al sistema, con manuale operativo.
4. Test end-to-end, documentazione tecnica e hand-over del codice sorgente.
Cerco una soluzione chiavi in mano, pronta per la certificazione e per l’avvio sia online sia in punto vendita.
