Most healthcare app developers can build a form. Very few can build a HIPAA-compliant, AI-powered mental health platform that handles patient intake via voice, runs therapy session tracking, monitors mood in real time, and escalates crisis alerts — all from a single codebase deployed on Azure. I've done exactly that. Working with a US-based surgeon, I architected and delivered a full-stack mental health platform from the ground up — voice AI intake via Twilio IVR, AI chatbot with mood tracking, therapy session management, medical scribe (voice-to-text), patient alerts and suggestions, and a full mobile and web experience. The platform launched in the US and now serves 1,000+ patients with 4,000+ registrations. That's what I build — not prototypes, not MVPs held together with shortcuts. Production systems that handle real patients, real clinical data, and real compliance requirements. WHAT I BUILD FOR HEALTHCARE → Mental Health Platforms — End-to-end therapy apps: patient intake, mood tracking, session management, crisis alerts, and AI-driven suggestions → Voice AI & IVR — Twilio IVR, voice-to-text, AI voice intake, and real-time transcription using Azure Speech and medical scribe workflows → AI Chatbots for Clinical Use — HIPAA-compliant chatbots for patient intake, symptom collection, mood check-ins, and escalation triggers → Telehealth & Therapy Session Tools — Video consultations, session notes, treatment tracking, and provider dashboards → HIPAA-Compliant Azure SaaS — Secure, auditable healthcare platforms built on Azure App Services, SQL Database, Key Vault, and RBAC → EHR Integration — Epic and AthenaHealth API integrations, HL7/FHIR data pipelines, and patient record sync → Mobile & Web — React Native mobile apps + Next.js/Blazor web platforms — one codebase, consistent clinical experience PROVEN RESULTS (not estimates) → Mental Health Platform (US) — 1,000+ patients served, 4,000+ registrations, voice AI intake, mood tracking, AI chatbot, crisis alerts, medical scribe — live in production → Clinic Management SaaS — 3,000+ patient check-ins/month across 20+ clinic locations — real-time digital queue, SMS alerts, multi-site ops — 3-year engagement, $76K+ → Medical Document Intelligence — Azure AI Search for clinical records; document retrieval from hours to minutes → RAG Clinical Data Pipeline — Automated clinical reporting replacing multi-day manual process with same-day automated output WHY HEALTHCARE CLIENTS STAY FOR YEARS Healthcare apps fail for one of three reasons: they're not built to clinical workflow, they're not HIPAA-compliant by architecture, or they fall apart when the patient volume scales. I design for all three from day one. HIPAA compliance isn't a checkbox I add at the end — it's in the data model, the API design, the Azure configuration, and the audit logging. Clinical workflows aren't assumed — they're mapped before a single line of code is written. I hold 5 Microsoft Azure certifications (AZ-900, AZ-204, AZ-104, AZ-305, AZ-400). I've integrated with Epic and AthenaHealth. I've built voice AI intake with Twilio. I've shipped mobile and web healthcare apps to real US patients. My clients don't come back because I'm available. They come back because what I built is still running — and still growing. MY HEALTHCARE STACK Backend: ASP.NET Core · C# · .NET 8 · Blazor · Node.js · Entity Framework Azure: App Services · Functions · Azure Speech · Cognitive Services · OpenAI · AI Search · Blob · Key Vault · SQL Database Voice AI: Twilio IVR · Voice-to-Text · Medical Scribe · Real-Time Transcription AI / Chatbot: Azure OpenAI · LangChain · RAG Pipelines · NLP · Mood Analytics Mobile & Web: React Native · Next.js · Blazor · Tailwind CSS EHR / Interoperability: Epic API · AthenaHealth API · HL7 · FHIR Compliance: HIPAA-compliant architecture · Azure RBAC · Audit logging · Secure API gateways DevOps: Azure DevOps · GitHub Actions · Docker · CI/CD Pipelines MY PROCESS → Step 1: Map the clinical workflow — patient journey, provider needs, compliance requirements → Step 2: Design HIPAA-compliant Azure architecture — security, audit, and data model built in from the start → Step 3: Build mobile and web in parallel — consistent experience across all patient touchpoints → Step 4: Integrate AI features — voice intake, chatbot, mood tracking, medical scribe — incrementally and testably → Step 5: Connect to EHR systems (Epic, AthenaHealth, FHIR) where required → Step 6: Deploy with CI/CD, monitoring, and full documentation — then stay available as the platform grows IS THIS YOU? → You're building a mental health or clinical app and need a developer who understands both the tech and the clinical workflow → You need HIPAA compliance built in — not bolted on after launch → You want voice AI, chatbot, or medical scribe features and need someone who has shipped these in production → You need mobile and web — and don't want two separate teams

I help founders and product teams turn ideas into production-ready apps - web, mobile, and AI-powered - without burning months or budgets on the wrong approach. 430+ projects. 52,000+ hours on Upwork. $2M in delivered work. 100% Job Success Score. Top Rated Plus. Top 3% globally. Those numbers did not come from small tasks or quick fixes. They came from building real products for real businesses, most of which are still running in production today. Several helped clients raise good amounts in funding. I work with founders and product teams across the US, UK, and Australia. My core focus is full stack web development, mobile app development with Flutter and React Native, and AI integration systems built with n8n, Make, OpenAI API, LangChain, and RAG pipelines. More than 13 years of this work has taught me one thing: the most expensive decisions get made before a single line of code is written, and that is exactly when I get involved. MOBILE APP DEVELOPMENT Flutter and React Native for iOS and Android. Social platforms, booking systems, healthcare apps, AI-powered mobile products, and fintech tools. Clean architecture, complete App Store and Play Store deployment, and backends built to grow with your users, not break under them. FULL STACK WEB AND SaaS DEVELOPMENT React, Next.js, Node.js, Python, Drupal, Laravel. MVPs live in two weeks. Multi-tenant SaaS platforms in four to five weeks. Scalable architecture, third-party API integrations, admin dashboards, CRM systems, payment gateways, and documentation that holds up when the next developer opens the repo. AI INTEGRATION AND INTELLIGENT SYSTEMS n8n, Make, OpenAI API, Claude API, LangChain, RAG pipelines, AI agents, LLM-powered SaaS features, AI chatbot development. If your team is still handling manually what a system should be handling automatically, that is the exact problem I solve. Not a prototype. A production workflow that runs every single day and saves real hours. TECH STACK Mobile: Flutter, React Native, Swift, Kotlin Frontend: React, Next.js, TypeScript, Vue.js, Tailwind CSS Backend: Node.js, Python, Drupal, Laravel, PHP AI and Automation: OpenAI API, Claude API, LangChain, n8n, Make, RAG, AI Agents Cloud: AWS, GCP, Docker, CI/CD Pipelines Database: PostgreSQL, MySQL, MongoDB, Firebase, Supabase Payments: Stripe, PayPal, In-App Purchases Integrations: REST APIs, GraphQL, Webhooks, Zapier, CRM Systems HOW I WORK Before any code gets written, I want to understand exactly what you are building and why. That conversation typically prevents weeks of rework and thousands in avoidable costs. I validate ideas, catch architecture mistakes early, and give you a realistic plan instead of an optimistic one. Fast responses. Clear milestones. No inflated timelines. No surprise invoices. Most of my clients have been working with me for years. That says more than any badge or metric. If you have an app, a platform to scale, or a workflow to automate, send me a message. I will come back with a specific, honest plan.
