I am a licensed therapist building a web app that helps therapists and clients be more connected with homework throughout the week. The app was built using Lovable (an AI app builder) and I need an experienced healthcare developer to review what was built, clean it up, fix any security gaps, and confirm it meets HIPAA technical requirements. This is a startup-stage project. I am the sole founder. I need someone who can communicate clearly with a non-technical person and explain what they find and why it matters. What I Need You To Do: Review all code generated by Lovable and identify security vulnerabilities Confirm or fix data encryption at rest and in transit Review every third-party service or vendor the app connects to and flag any that would require a Business Associate Agreement (BAA) Confirm that client-entered content (homework reflections) cannot be accessed by any unauthorized party Ensure the therapist and client login system is secure and roles are properly separated Confirm that the permanent crisis support button on all client-facing screens cannot be removed, bypassed, or overridden Provide a short written summary of what you found, what you fixed, and what still needs attention What This App Does NOT Do: No billing or insurance No video or scheduling No AI responding to client content No users under 18 What I'm Looking For in You: Demonstrated experience building or auditing HIPAA-compliant SaaS applications Familiarity with BAA requirements and which vendors (cloud hosts, email services, AI APIs) typically require them Experience with web apps built on modern frameworks (React, Next.js, or similar) Ability to explain technical findings in plain English Bonus: experience with mental health, therapy, or healthcare technology specifically To Apply, Please Answer These Three Questions: 1. Describe a HIPAA-compliant project you have worked on. What was the app, what did you build or audit, and what vendors required BAAs? 2. What is your process for reviewing code built by an AI tool like Lovable or Bolt? 3. What is one common HIPAA technical safeguard that early-stage health app developers frequently miss? Applications that do not answer all three questions will not be considered. This app handles real therapy client data. I take privacy and safety seriously and I am looking for someone who does too, not just someone who can write compliant-sounding documentation. Please only apply if you have genuine healthcare tech experience.

We're looking for a designer to help with a few focused updates across our golf tee time app (mobile) and web app (mobile + desktop). These are well-scoped improvements, not a full redesign — good fit for someone who can move fast and communicate clearly. What we need: Mobile app home/discovery screen — refresh the top half (above the fold) Course detail page states — redesign how we handle: - Courses with temporarily unavailable tee times - Courses with no available tee times Needed across: mobile app, and web app (both mobile and desktop breakpoints) Deliverables: - Polished, dev-ready mockups (Figma preferred) for each surface/breakpoint - 1–2 rounds of revisions based on feedback Ideal candidate: - Strong portfolio of mobile + responsive web UI work (consumer apps a plus) - Comfortable working from existing brand/style guidelines - Experience designing clear empty/unavailable states is a plus - Fast turnaround, clear communicator, used to short, well-defined engagements Scope: Hourly, short-term engagement. We expect this to take a modest number of hours across both pieces, with potential for more ongoing design work if it's a good fit.

We are building a production-grade automation and management platform for a physical Android device farm. Hardware environment: Google Pixel 7A devices Graphene OS (privacy-focused Android) Multi-user profiles (up to 31 users per device) Multiple accounts per user Devices run 24/7 in controlled environments with remote access Core goals of the system: Reliable login and account management across many users and devices Account profile editing at scale Content posting automation with strong human-like behavior Proxy / network management per account or user Central account database and health monitoring Clean web dashboard for monitoring device status, account status, activity logs, and performance metrics Full remote desktop compatibility so operators can manage the system daily Architecture that can scale from one box (20 devices) to dozens of boxes Critical technical requirement: The system must use hardware-level input simulation (HID principles) rather than pure software/ADB automation. Previous pure ADB approaches caused detection issues. We need a more robust, human-like interaction layer that works reliably inside Graphene OS multi-user environments. What we are looking for: Experienced Android automation / device farm teams or senior developers Strong preference for US-based agencies or developers with proven track records and excellent Upwork reviews Demonstrated experience with: – Android multi-user / work profile automation – Graphene OS or other custom Android ROMs – HID / hardware input simulation – Large-scale device orchestration – Building operator dashboards and remote management tools Project structure preference: We prefer teams that can deliver a solid, working MVP in significantly fewer hours than typical offshore estimates by using efficient architecture and senior talent. We are open to higher hourly rates in exchange for higher quality and faster, cleaner delivery. Engagement type: Hourly (preferred) or fixed-price milestone structure. We value clear communication, weekly progress demos, and clean, well-documented code that our internal team can maintain and extend. Please include in your proposal: Relevant past projects involving Android device farms, multi-user automation, or HID-level input simulation Your team’s location and typical communication hours (US time zones preferred) Rough hour or milestone estimate for a complete, production-ready system on the described hardware Your standard hourly rate or fixed-price approach Any questions you have about the technical constraints (Graphene OS multi-user + HID) We are ready to move quickly with the right team. Looking forward to speaking with experienced US-based agencies and senior developers who have solved similar device-farm challenges.Must-Have Skills Python (primary language for orchestration, scripting, device control, and backend logic) Android automation at a deep level (not just basic Appium) HID (Human Interface Device) input simulation — this is the most critical skill. They need real experience injecting hardware-level touch, swipe, and keyboard events (USB HID, Bluetooth HID, or equivalent low-level methods) Graphene OS / custom Android ROMs and multi-user profile handling ADB (advanced usage, even though pure ADB is not enough) Multi-device / phone farm orchestration (controlling 20+ devices simultaneously) Proxy management and network routing per user/account Account/session management systems Strongly Preferred Skills Kotlin or Java (for any Android-side components or custom input services) UIAutomator / Accessibility services / low-level input injection techniques Building operator dashboards (Python backend + React/Vue/HTML frontend is common) Database design (PostgreSQL, SQLite, or MongoDB for account health, logs, and status) Remote access tools (AnyDesk, RustDesk, VNC, or custom solutions) Linux system administration (since the control PC will likely run Linux) Experience with residential/mobile proxy gateways and sticky sessions.

Hello. I am looking for someone to give occasional help for an app I built for the company We Win Games. I was working with another developer, but he’s moving on to another job so I have to get it all transferred to you. We have about 100 active users and there are still bugs that appear that need fixing. I need someone to communicate with me in WhatsApp and to be able to fix bugs or add features when we need them. I’ll give you access to everything. We have it on Apple developer and use Vercel and Supabase. All based on the web app wewingamessales.com. Thank you!

I am seeking an experienced senior full-stack / SaaS / AI developer or small development team to architect and build the MVP for a new premium digital platform. This is an early-stage product, but it is well beyond the idea stage. Significant work has already been completed defining the business requirements, user experience, workflows, visual direction, administrative requirements, privacy/security principles, and MVP scope. The initial engagement is to build the first SaaS product and underlying technical foundation for a larger business that may expand into additional digital capabilities over time. This is not a basic website project or generic AI chatbot. The MVP will require a secure authenticated customer application and administrative environment incorporating structured records, document/image uploads, AI/API-assisted processing and research, generated customer deliverables, subscription/payment capabilities, and administrative workflows. High-Level MVP Requirements The application is expected to include capabilities such as: Secure customer registration and authentication Customer dashboard and account management Creation and management of structured customer records Secure photograph and document upload/storage AI/LLM and third-party API integrations AI-assisted research, analysis, and content generation Structured storage of AI/research results Professional customer-facing document/report generation Private administrative dashboard and workflow tools Human review/approval capabilities Subscription and payment integration Role-based permissions and appropriate access controls Privacy-focused data architecture Production deployment, backups, logging, and monitoring Responsive, polished web-based user experience The platform will handle information customers consider private and potentially sensitive. Security, privacy, data minimization, and access control therefore need to be considered at the architectural level from the beginning. Technology Approach I am deliberately not prescribing a technology stack. I have done some early experimentation with low-code tools to help visualize the concept, but I am open to: Traditional full-stack development Low-code platforms such as Bubble Hybrid architecture Other appropriate modern approaches I want the selected developer to recommend the architecture based on the actual product requirements, including development speed, security, AI/API integration, maintainability, scalability, operating cost, portability, and avoidance of unnecessary vendor lock-in. Existing Product Work Detailed product-definition materials have already been developed, including: Product and MVP specifications User/customer workflows Administrative workflows Data requirements AI/research requirements Privacy/security requirements Customer deliverable concepts Visual/design direction MVP acceptance criteria Future product considerations These materials and the detailed business concept will not be included in the public posting. They will be shared with selected finalists after an NDA/confidentiality agreement is executed. The selected developer will therefore not be starting with a blank sheet of paper. Developer Profile I am looking for someone with demonstrated experience building production SaaS applications and who can contribute technical judgment rather than simply execute instructions. Relevant experience should include several of the following: Full-stack SaaS development AI/LLM API integration Third-party API integration Relational database architecture Authentication and authorization Secure file/document storage Administrative portals and workflows Subscription/payment integration Automated PDF/report generation Privacy/security architecture Cloud deployment Monitoring and logging I am particularly interested in developers who have previously taken a new SaaS product from requirements/architecture through working production MVP. Engagement I anticipate a milestone-based fixed-price engagement. The first milestone will likely involve reviewing the confidential specifications, validating/refining the MVP scope, recommending the technology architecture, confirming the data/security approach, and producing an agreed development plan before proceeding into the full build. I am open to an ongoing relationship with the right developer as the platform grows, but the application should be architected and documented so that the business retains control of its technology and another qualified developer could support it if necessary. Please Answer These Four Questions 1. Relevant experience: Please provide two examples of SaaS/AI applications you have personally helped build. Briefly explain what the products did, your specific role, the technology used, and whether you were involved from architecture through production deployment. 2. Technology selection: Without knowing the confidential business concept yet, what factors would lead you to recommend traditional full-stack development vs. Bubble/low-code vs. a hybrid architecture for a new AI-enabled SaaS MVP? 3. AI and security experience: Please describe your experience integrating AI/LLM services into production applications that also contain private customer information, uploaded documents/images, authentication, and role-based access controls. 4. Development approach: When a founder already has detailed product requirements, workflows, and design direction, how do you normally take that material from technical architecture → MVP development → testing → production launch and handoff? Please do not provide a generic proposal. I am particularly interested in your answers to these four questions. If your response does not include answers to these four questions, it will be disregarded in order to save your time and mine. Additional product information will be provided to selected candidates following execution of an NDA.
