I need a small Android test app written in Java that uses the front-facing camera and investigates whether it can trigger screen flash intensity similar to the phone’s native camera app.

Not accepted:

- Setting screen/window brightness to 100%
- Displaying a white or colored full-screen View
- CameraX ScreenFlash using a bright overlay
- Rear-camera LED torch mode

Possible areas to investigate:

- Camera2 vendor tags
- CameraX/Camera2 Extensions
- Samsung or other OEM private APIs
- DisplayManager, HBM, HDR, or system display services
- APIs requiring special permissions or OEM access

Deliverables:

- Complete Java source code, not kotlin
- Installable APK
- Clear testing instructions
- Logs showing which API/method was attempted
- Comparison with the native front-camera flash
- If impossible for a normal APK, a technical explanation of the required system permission, OEM API, root access, or system signature

This is a research/prototype project, not a production camera app.

Job Title: Senior Capacitor / Native Mobile Developer (iOS/Android) for Privacy-First AI App

Job Category: Mobile App Development
Skills: Capacitor, React, iOS Development (Swift), Android Development (Kotlin/Java), In-App Purchases (IAP), On-Device Machine Learning (LiteRT / local LLMs)

Job Description:
We are looking for an experienced Native Mobile / Capacitor Developer to take our fully-built React/Vite web application across the finish line to the Apple App Store and Google Play Store.

Our app, is a privacy-first, on-device AI companion for cycle and pregnancy tracking. 100% of the core app logic, UI, and AI architecture (rules engines, memory structures, RAG) has already been built. We need you to handle
the physical-device validations, native iOS plugin development, and store billing sandboxes that require real hardware and console access.

Your Responsibilities (The "Last Mile"):

1. iOS Native Plugin Development (App-Owned Gemma):
• The Android implementation for our local LLM (@capacitor/local-llm) is already compiling.
• We need you to build the iOS equivalent (DottiLocalGemma plugin) in Swift. This requires implementing background URLSession model downloading, backup-excluded Application Support storage, native SHA-256 verification, and a
local LiteRT-LM binding.
2. Physical Device Validation (AI Air-Gap & Inference):
• Test our OS-native provider air-gaps on real iOS 26+ (Apple Intelligence) and Android hardware (AICore/ML Kit Prompt).
• Benchmark model loading, warmup, streaming generation, RAM usage, and thermal behavior.
• Ensure the app fails gracefully to our deterministic rules engine under high memory pressure or low battery.
3. Billing Sandbox & Store Config:
• Configure 5 canonical subscription products on App Store Connect and Google Play Console.
• Validate sandbox purchases, cancellations, refunds, and restores on physical devices using our existing dottiPurchases.js architecture.
4. Background Execution:
• Implement our deferred "background pulse" using the @capacitor/background-runner plugin to run scheduled background tasks (e.g., memory consolidation).
5. Final Lifecycle & Accessibility Gates:
• Run TalkBack (Android) and VoiceOver (iOS) accessibility passes.
• Validate notification permissions, deep links, foreground/background lifecycle teardowns, and app lock behaviors.


What We Provide:

• A pristine, production-ready React/Vite SPA codebase with zero lint warnings and fully passing test suites (3,700+ tests).
• Extremely detailed specifications and runbooks for every native task (e.g., NATIVE-SHIPPING-READINESS.md).
• Fully baked backend services (Cloudflare Workers) and pre-converted LiteRT-LM models hosted on our R2 buckets.

Requirements:

• Deep expertise with Capacitor and writing custom native plugins (Swift for iOS is mandatory).
• Proven experience deploying apps to both the App Store and Google Play, specifically configuring auto-renewable subscriptions (In-App Purchases).
• Access to physical iOS and Android devices for testing (specifically newer devices capable of handling on-device AI/ML workloads).
• (Bonus) Experience with on-device AI, LiteRT, or MediaPipe.

To Apply:
Please include links to previous Capacitor/Ionic apps you have published to the stores, and briefly mention your experience writing custom iOS Capacitor plugins.


Note: Device Hardware: Because of the Models / Apple Intelligence requirements, do you have an iPhone 15 Pro or newer (for Apple Intelligence support) and a high-RAM modern Android device to properly benchmark the model execution? Add this to your response.

We run a fantasy football content site and want to add a daily fantasy sports (DFS) lineup optimizer tool — similar in function to dailyfantasyoptimizer.com — that lets users upload player pools/projections and generate optimal DraftKings (and ideally FanDuel) lineups.

Core features needed:
- Linear programming / optimization engine to generate optimal lineups under salary cap constraints (standard knapsack-style DFS optimization)
- CSV upload for player salaries + projections (matching DraftKings/FanDuel export format)
- Support for player exposure limits (max % of lineups a player appears in)
- Stacking rules (e.g., QB + WR from same team, game stacks)
- Bulk lineup generation (50-150 unique lineups per run)
- Export lineups in DraftKings-compatible CSV format for direct upload
- Clean, simple single-page UI — no manual required to use it
- Start with NFL support (single sport is fine for v1; architecture should allow adding NBA/MLB later)

Nice to have (not required for v1):
- Editable/custom projections per player
- Basic backtesting against historical slates
- Player pool filtering (by position, salary, team)

What we need from you:
- Experience building optimization tools (linear/integer programming — PuLP, OR-Tools, or similar)
- Familiarity with DFS site formats (DraftKings/FanDuel) is a strong plus
- Ability to deliver a working, deployable web app (front end + backend), not just a script
- Clear communication and milestone-based delivery

Please include in your proposal: relevant past projects (optimization tools, sports betting/DFS tools, or similar), your suggested tech stack, and a rough timeline/cost estimate for a v1 NFL-only version.

Project: Premium One-Page Tutoring Flyer in Photoshop

I need a designer to create a polished one-page flyer for an in-person computer science tutoring and software project mentorship service in Manhattan.

The flyer will be posted in cafés, school- and university-adjacent locations, libraries, coworking spaces, and neighborhood bulletin boards. It should feel professional, modern, credible, and high-end. It should not look like a generic homework-help flyer, kids’ coding camp ad, tear-off-tab notice, or stock-photo business flyer.

The audience is students and serious project builders who need hands-on help with real programming projects. Scheduling and payment are handled through Wyzant.

Please use the exact copy below. You may adjust hierarchy, spacing, typography, and line breaks, but do not rewrite the text.

Flyer copy:

COMPUTER SCIENCE PROJECT RESCUE

Java • C++ • C# • JavaScript/TypeScript • Angular • Node.js
HTML/CSS • SQL/Databases • APIs • Git/GitHub • Linux/Hosting

Bring the laptop, code, assignment, capstone, app, game, website, or portfolio project.
We work directly in the actual development environment.

$125/hr
Manhattan in-person sessions at home, campus, or agreed public location.
90-min minimum.

Book through Wyzant for secure scheduling and payment.

[QR CODE]

Design requirements:

The final deliverable must be a layered Adobe Photoshop PSD file, not a flattened design. The QR code will be provided and must be placed in its own clearly named layer or layer group so it can be replaced later if needed.

Please keep the file cleanly organized, with reasonably named layer groups such as title, technology line, description, pricing, location, Wyzant CTA, QR code, background, and decorative elements.

Do not use AI-generated images, AI-generated poster layouts, or AI-generated text effects as the basis of the design. I am looking for a deliberately designed Photoshop layout with editable text, separate design elements, and cleanly organized layers. Template-based or flattened artwork is not suitable for this project because I need to be able to edit and replace elements later.

The flyer should be designed for professional printing at final US Letter size, 8.5" x 11". Please include a standard 0.125" bleed on all sides, so the full artwork size is 8.75" x 11.25". The design may use full-bleed background color or graphics, but all important text and the QR code must stay inside a safe margin. Do not include crop marks in the print-ready PDF.

The visual hierarchy should make the message immediately clear: headline first, then technology line, project description, price/location, Wyzant booking instruction, and QR code.

Preferred style:

Professional, modern, technical, clean, high-contrast, and uncluttered. Subtle code/editor motifs are fine. Avoid cartoon imagery, childish coding-camp styling, classroom stock photos, handshake/business stock photos, excessive icons, and tear-off tabs.

I am open to different visual directions, including minimal premium tech, bold project-rescue, or academic/professional hybrid. The key is that the flyer should look serious enough for university-adjacent locations, coworking spaces, cafés, and neighborhood boards.

Required deliverables:

Layered Adobe Photoshop PSD file with organized, clearly named layer groups
QR code on its own clearly named layer or layer group
Print-ready PDF with 0.125" bleed and no crop marks
PNG or JPG preview for review

Please include a brief note about your approach and show examples of clean flyer, poster, or information-design work if available.

Project Overview:
We are looking for a Senior Full-Stack Developer to build a high-performance, secure "Mega Offerwall Earning App" from scratch. The system must be highly optimized to support 500+ concurrent users with zero lag and solid security.

Key Technical Stack:
- Backend: Node.js or Go (Golang)
- Database & Caching: MongoDB & Redis
- Frontend: Native Android Integration

Core Requirements & Challenges:
1. Anti-VPN & Anti-Proxy System: Robust detection mechanisms to block fake traffic, device emulators, and unauthorized geo-locations.
2. Offerwall Integration: Integration of 25+ major ad networks and offerwall APIs.
3. Custom Postback Queue Management: A secure, bulletproof postback handler with Redis to prevent double-spending and track accurate user conversions.

Project Architecture & Scope:
- Project Scale: Large (1 to 3 months duration)
- Architecture: Scale-ready, microservices or clean monolithic architecture with properly optimized API endpoints.

Payment Term Conditions (Strict):
This is a fixed-price contract. Payment will be strictly milestone-based via Upwork Escrow. No advance payments. Milestones will be released ONLY after we receive, comprehensively test, and verify the deliverables to ensure everything works flawlessly under stress conditions.

If you have proven experience building complex tracking, ad-network integrated, or high-traffic earning applications, please submit your proposal along with your portfolio/github.

The Vision:
I’m a high-level solopreneur running multiple businesses, and I am heavy into AI, voice agents, and building automated systems. I know exactly what I want my tech to do, but I don't have the time to sit in the weeds doing the implementation.

I am looking for a sharp, driven Technical VA to start out by taking the technical heavy lifting off my plate. But honestly? If you have ambition, drive, and solid morals, this could easily evolve into a very lucrative, long-term technical partnership as we launch new business ventures.

The Initial Test Project (Budget: $100):
We are going to start with a single, 4-to-5 hour setup. It involves getting a Java system running inside my Claude Code CLI environment.

I’ll hand you an SOP.

We will hop on a quick session to map it out.

You go execute, troubleshoot, and get it working.

We regroup and finalize it.

What the Long-Term Role Looks Like:
If we vibe on the first project, this turns into an ongoing, flexible role (5–10+ hours/week). You will be my technical right hand.

Vibe-Coding & Integrations: Making sure websites are connected, pipelines (like GoHighLevel) are talking to each other, and new tech ideas are deployed smoothly.

Tech Support: Figuring out the systems, code, or terminal commands that I simply don't want to learn.

Organization: Keeping our technical projects on track and making sure we both know exactly what the next move is.

Who You Are:

You understand tech platforms, GitHub, and AI tools (especially Claude Code).

You are a self-starter who doesn't need babysitting. If you hit an error, you try to solve it before bringing it to me.

You are organized, fluent in English, and communicate clearly.

You are hungry. If my businesses do well, you do well.

To Apply:
Start your proposal with the phrase "I figure sh@t out" so I know you read this. Keep it brief—tell me about your experience with AI tools, Claude Code, or system integrations, and let’s build something.

We're a children's footwear brand building a western boot on a natural, anatomical foot shape — a real cowboy boot that fixes the fit problems in traditional kids' boots (narrow toes, raised heels, too much toe spring). We're looking for a footwear developer / technical designer to help take it from concept to a manufacturer-ready package.

We'd start with a small, paid diagnostic sprint — a short engagement to pressure-test feasibility before any larger commitment. We'll scope the later phases together based on what it finds.

The product in one line: a real cowboy boot, built like the grown-up ones, shaped like a kid's foot. Priorities: anatomical toe box · zero/low internal drop · low toe spring · secure heel fit (via an exposed inner side zip) · easy on/off · child-safe & compliance-ready · premium, leather-forward look.

What we already have

A clear product concept and founder-defined fit priorities
An early 3D concept model (a communication tool — not a production last)
Direction on size range, material, price, and MVP scope
What we need help with

A new anatomical last — creation, not modification of a western last
Shaft/stitch direction, a notched zero-drop outsole, material spec, construction
Tech pack, factory communication package, sample development, landed-cost feasibility
Who we're looking for — experience across several of: children's footwear · boots / western / side-zip footwear · anatomical / barefoot / natural-foot footwear · last development (creation, not just modification) · manufacturer-ready tech packs · overseas factory development · early-stage brands and fit testing. We especially want someone whose reference points are anatomical/kids footwear, not a traditional western bootmaker who'll instinctively narrow the toe. This is a fit-architecture and cost-feasibility project, not a fashion-sketching one.

Phased scope (confirmed after the diagnostic): 1) Diagnostic sprint → feasibility memo + recommended sequence · 2) Last & fit strategy · 3) MVP design development · 4) Manufacturer-ready tech pack · 5) RFQ / factory-sourcing support.

To apply, please include: a brief overview of relevant experience + work samples; your answers to the questions below; and a proposed phase-based scope with your own fees (diagnostic sprint as a separate line item) and a rough timeline.

Questions

Children's footwear experience? Boots / western / side-zip footwear? Anatomical / barefoot / wide-toe / zero-drop?
Can you create (not just modify) a last?
Do you produce manufacturer-ready tech packs?
Can you advise a 10C sample-size last strategy before a full graded run?
What inputs do you need from us, and what would you deliver?
How would you split responsibilities between developer and factory?
The biggest risks you see?
At a high level, how would you approach keeping it western with an anatomical toe, and securing the heel in a zero-drop side-zip boot? (Your approach, not a full solution.)
Relevant factory relationships? Can you support sample review / revision comments?
Estimated cost and timeline per phase?

Hello,
I am looking to hire an experienced Android developer for modifications to my existing APK/app project.
Scope of work:
1. Change the popup logo to a new custom logo (I will provide the design).
2. Rename the title bar text (currently showing a different name) to my new app name.
3. Modify the "Send Token" button functionality.

* Strong experience in Android (Java/Kotlin)
* Experience with local databases (Room/SQLite
Looking forward to working with you.

Thank you.

What this is: We run native ARM64 Android 15 (redroid) in containers on cloud ARM servers. A headless Android virtualization platform for automation and scale. We need someone who lives in the AOSP build system, not someone who writes Android apps. These are completely different jobs; please only apply if you've actually built AOSP from source.
The engagement: Contract, fixed-price milestones to start, with potential for an ongoing relationship if it's a good fit. Remote.
What you'd own:

- Reproduce and document our redroid Android 15 image build on a clean build server (first milestone — see screening task).
- Maintain and evolve the image: Android security patch updates, version bumps, build pipeline hardening.
- Build per-instance device-profile customization — coherent system-property bundles (locale, timezone, build fingerprint, device model) applied at runtime, using redroid's property-override support.
- Own the build-to-deploy pipeline: repo/manifest management, custom patches, image packaging, container deployment.

Required, you must have done these, and we'll verify:

- Built AOSP from source (repo, lunch, make, manifests, local_manifests) and debugged real build failures.
- Worked with redroid, Cuttlefish, Waydroid, or comparable container/virtualized Android — or equivalent device bring-up / custom ROM experience (LineageOS, GrapheneOS, etc.).
- Comfortable in Android platform internals: build.prop, system properties, the HAL layer, what's baked into an image vs. set at runtime.
Linux, Docker, and the ARM64 cross-compilation toolchain.
- Git, and a habit of committing your work so others can reproduce it.

Bonus
- Kernel-adjacent comfort (binder, container isolation patches).
- Public contributions we can read — custom ROM commits, AOSP patches, relevant open source.

Not what we're looking for: app developers (Kotlin/Java app work is a different role), anyone who conflates "Android development" with "building Android," or "I haven't done AOSP but I learn fast."

How we hire: We do a small paid screening task before any larger commitment — real work, real pay, and it's how we assess fit for both sides. We verify deliverables by running them, not by reviewing claims. Direct, evidence-based, fixed-price milestones with sign-off as the payment trigger.

To apply: Tell us (briefly) about an AOSP build you've owned — what device/target, what broke, how you fixed it. Link any public work. We read for specifics; generic applications won't get a response.

Connect Existing Dashboard to DenGro, Dentally, Meta & Google

I'm looking for a developer to connect an existing marketing dashboard to our data sources.

The dashboard has already been designed and built. I'm simply looking for someone to integrate the data so the dashboard updates automatically.

Data Sources

The dashboard needs to pull data from:

* **DenGro CRM**
* **Dentally**
* **Meta Ads**
* **Google Ads**

DenGro supports Zapier and webhooks, and I'm happy for you to recommend the best approach for connecting the systems.

Dashboard Metrics

The dashboard already contains KPI cards which need populating with live data, including:

Meta

* Leads In
* Ad Spend
* Cost Per Lead
* Consultations Booked
* Cost Per Booked Consultation
* Appointments Attended
* FTAs / Cancellations
* Treatments Started

Google

The same KPI cards for Google Ads.

Filters

The dashboard includes two filters:

* **Week Commencing (W/C)**
* **Treatment**

When these filters are changed, all KPI cards should update accordingly.

Requirements

I'm looking for someone with experience integrating APIs, webhooks or Zapier into existing web applications.

Please let me know:

* Your experience with similar integrations
* Whether you've worked with DenGro or Dentally before (not essential)
* Your proposed approach
* A fixed price for connecting the dashboard to these data sources

The dashboard itself is already complete. This project is purely for connecting the data sources and ensuring the reporting updates correctly.
