Tired of developers who don't understand the difference between a patient record and a grocery list? Building healthcare software falls apart when your team doesn't speak the language of clinical workflows, FHIR, or HIPAA. You burn weeks and budget on "lost in translation" errors between your clinical vision and the people writing your code. I'm Dr. Opeyimika Aremu, a Medical Doctor (MBBS) and full-stack engineer. I build clinically sound, HIPAA-ready healthtech MVPs because I have lived the problems you're trying to solve, on both sides of the screen. WHAT I BUILD: ► HIPAA-Compliant Healthcare Web Apps Patient portals, provider dashboards, and medical web apps (including PWAs) with HIPAA and GDPR compliance, data encryption, audit logs, and role-based access control (RBAC) from day one. ► Telehealth & Patient Management Systems Appointment scheduling, patient onboarding, automated reminders and follow-ups, and care coordination for clinics, practices, and digital health startups. ► AI Chatbots & Medical AI Assistants OpenAI, Claude, and Gemini API integration. RAG chatbots that answer from your own medical documents, AI clinical reporting, and document data extraction, with clinician review built in. ► EHR / EMR & FHIR Integration Connect your app to electronic health records using FHIR, HL7, and CCDA. Custom API integrations between EHR/EMR systems, labs, pharmacies, and third-party services. ► Healthcare SaaS & MVP Development Full-stack builds in React, Next.js, Node.js, and Python (FastAPI / Flask). From idea to launched product in 30 to 60 days, MVP through scalable production. ► Custom Healthcare Software & Backend APIs PostgreSQL, MongoDB, and Supabase databases, secure authentication (Auth0), REST APIs, and webhooks that connect your systems. ► Payments, Billing & Workflow Automation Stripe checkout and subscription billing, e-signature and contract pipelines, automated patient communications, and live analytics dashboards. WHY HEALTHTECH FOUNDERS TRUST ME: ✓ 100% Job Success Score — every client satisfied, every project delivered ✓ I'm a doctor, so I catch the clinical edge cases your developers will miss ✓ Cut BioNova's lab reporting from 8 hours to an 8-minute workflow ✓ Scaled Hakeim's RAG engine to 20,000+ clinical mindmaps with near-zero hallucination ✓ Shipped HIPAA-compliant patient systems (OrthoStart) with full audit trails ✓ Top Rated status — consistently high feedback and on-time delivery HOW I WORK: 1. REQUIREMENTS: I listen first. Understanding your clinical and business goal is more important than the tech stack. 2. ARCHITECTURE: I design the system before writing code. Scalable, documented, and production-ready system design before any code is written. 3. BUILD: Weekly updates, transparent progress, demo-ready milestones. 4. DELIVERY: Deployed, tested, monitored, with 30 days post-launch support. READY TO BUILD? If you're building something in healthcare and want a developer who already speaks clinical, send me a message with what you're working on. I'll tell you exactly how I'd build it and how long it will take. Let's turn your healthcare idea into a working product. Thanks. Dr. Opeyimika Aremu | Full-Stack AI Engineer & Medical Doctor

Broken FlutterFlow app? Stalled build? Just a Figma file? I rescue and ship FlutterFlow apps to the App Store and Google Play: MVPs, Firebase, Supabase, Stripe, AI, iOS + Android. Top Rated in year one: 17 jobs shipped, every review 5 stars. I reply in under 60 minutes. Hi, I'm Joseph, a senior FlutterFlow and Flutter developer based in Lagos, Nigeria, working daily with founders in the US, UK, EU and Australia, in English or French (full overlap with GMT/CET, mornings with EST/PST). Most FlutterFlow work on Upwork is one-off prototypes. Mine is not. Clients keep me on retainer after launch, because launch is when the real product work starts: the feature users actually asked for, the Firebase bill that needs restructuring, the store update that has to pass review this week. RECENT RESULTS - Abandoned build rescued in 3 weeks. Took over a half-finished FlutterFlow project, shipped it, still maintain it today. - Firebase costs cut ~70%. Restructured Firestore behind a live FlutterFlow app: nested subcollections and unbatched reads, as usual. - Fintech MVP in 45 days. 20-screen Figma design to live App Store launch. The founder hit his Series A demo with a week to spare. WHAT I FIX Stalled or abandoned FlutterFlow projects | App Store and Google Play rejections | Firebase and Firestore cost blowups | slow, janky or crashing builds | broken Stripe and RevenueCat payments | failed API and webhook integrations | messy data models and insecure Firestore rules | migrations from Bubble, Adalo and Glide into FlutterFlow WHAT I BUILD - FlutterFlow MVPs for iOS and Android: Figma to store approval in 30-60 days - SaaS platforms, marketplaces, booking systems, admin dashboards - AI features: OpenAI, Claude, Gemini, streaming, RAG, Whisper and ElevenLabs voice, support agents - Payments: Stripe Checkout, subscriptions, Stripe Connect, RevenueCat in-app purchases - Firebase and Supabase architecture, security rules, cost optimisation - Real-time chat, live updates and push notifications - Custom Flutter and Dart code where FlutterFlow's blocks run out QUESTIONS I GET ASKED Can you rescue a FlutterFlow app another developer abandoned? Yes, it is my most requested job. Most rescues take 1-3 weeks. I audit what exists, tell you honestly what is salvageable, then finish and ship it. How long does a FlutterFlow MVP take? 30-60 days from Figma to a live App Store and Google Play listing, for a typical 15-25 screen app. Can FlutterFlow build a complete production app? Yes: UI, backend, integrations, payments and store deployment. Where its blocks run out, I write custom Dart. Why is my Firebase bill so high? Almost always Firestore structure: nested subcollections, unbatched reads and listeners left open. Restructuring typically cuts the bill 50-80%. Do you design in Figma first? Yes: wireframes, user flows and dev-ready UI. Or I build straight from the Figma file you already have. Who owns the work? You do. Full FlutterFlow project and code export from day one, no lock-in. Will you stay on after launch? Yes. Most clients move to a monthly retainer for features, fixes and store updates. HOW I WORK Loom walkthrough at every milestone. Written docs and a handoff playbook. Honest pushback on architecture instead of quiet shortcuts. Fixed-price milestones so you always know the number before I start. START HERE (free, no pitch) Send your broken FlutterFlow project, your Figma file, or just the idea. Within 24 hours I send back a short Loom: what is actually wrong or how I would architect it, where the cost traps are, and what I would fix or build first. If we are not a fit, I will say so and point you somewhere better. Hit "Message" or "Invite to Job" and paste your project link. I will reply today.

Full Stack Developer specializing in Lovable, Replit, Base44, and Supabase, turning AI-generated prototypes into production-ready SaaS. Your app looked amazing in the demo. Then real users showed up, and now you're staring at broken auth, RLS policies blocking data no one meant to block, a Stripe integration that half works, and AI features that only behave when you're the one testing them. That's not a you problem. That's the gap every Lovable, Base44, Bolt, or Replit build hits at roughly the same point, AI tools get you 80% of the way to a real product, and the last 20% is the part that decides whether you can actually launch, charge real customers, and sleep at night. That's the part I handle. What you get when you bring me in: A real audit of what's actually broken, not guesswork, before a single line changes Auth that holds up under edge cases, not just the happy path Supabase RLS policies that are actually secure, not accidentally blocking your own users Payments that reliably fire, webhooks included, no silent failures AI features that behave the same for your users as they did in your demo Stack I work in: Next.js · React · TypeScript · Supabase (auth, Postgres, RLS, edge functions) · Tailwind CSS · Claude API · OpenAI · Stripe · Vercel · Cursor How I work: clear scope before anything starts, milestone-based delivery so you always know where things stand, and updates you don't have to chase down. You get software that actually works and clean code you fully own, no lock-in, no mystery architecture you can't touch later.
