I am a results-driven Python Developer specializing in FastAPI, Django, Flask, REST API development, AI integrations, and scalable backend systems. I build cloud-native, microservices-based applications using AWS, GCP, Docker, and Kubernetes, with strong expertise in PostgreSQL, MongoDB, and high-performance data pipelines. My work focuses on SaaS platforms, fintech systems, automation, and API integrations, delivering secure, production-ready solutions optimized for performance, scalability, and reliability. Then continue with your existing body (unchanged or slightly refined): I’ve worked on SaaS platforms, fintech systems, analytics dashboards, and API-heavy applications—handling everything from backend development to cloud deployment. My approach focuses on performance, security, and maintainability, ensuring your product is not just functional but built to scale. On the backend, I build robust RESTful APIs, optimize database performance, and implement secure authentication systems. I’m comfortable working with microservices, event-driven architectures, and third-party integrations (Stripe, Shopify, SnapTrade, etc.). I also bring experience in AI/ML integrations, data processing pipelines, and automation workflows—helping businesses leverage data effectively.

One of my clients grew revenue 500% after I rebuilt their core algorithm. Another called a $500K research platform I led the "gold standard" in their industry. That's the bar I work to on every project. I build AI-powered web and mobile apps from idea to production. For startups and scale-ups in healthcare, fintech, SaaS, and eCommerce. What makes me different from most full stack developers: I own the entire AI layer too. Not just connecting an API and calling it done, but designing RAG pipelines, LLM chatbots, OpenAI-backed features, and AI automation workflows that solve real business problems all inside production-grade React Native, React, and FastAPI apps. What I build for clients: → AI chatbots and assistants (OpenAI, LangChain, RAG, Pinecone) → AI-powered mobile apps (React Native, Flutter, iOS, Android) → SaaS platforms, MVPs, and full stack web apps → RAG systems: chat with documents, internal knowledge bases → REST APIs, microservices, and scalable backend architecture → Payment integrations (Stripe, Twilio) and cloud deployment (AWS, Docker) Industries I know deeply: healthcare, fintech, eCommerce, SaaS, edtech, logistics. 𝟏𝟎+ 𝐲𝐞𝐚𝐫𝐬 𝐨𝐟 𝐞𝐱𝐩𝐞𝐫𝐢𝐞𝐧𝐜𝐞. 𝟗,𝟕𝟎𝟎+ 𝐡𝐨𝐮𝐫𝐬 𝐨𝐧 𝐔𝐩𝐰𝐨𝐫𝐤. 𝟏𝟎𝟎% 𝐉𝐨𝐛 𝐒𝐮𝐜𝐜𝐞𝐬𝐬 𝐒𝐜𝐨𝐫𝐞.

12+ apps live on the App Store and Play Store — healthcare, fintech, education, food delivery, telehealth, and field services. Every one built end to end: architecture, UI, backend, third-party integrations, real device testing, and store submission. What I build: Flutter cross-platform apps (iOS + Android), Laravel backends, REST APIs, and FastAPI services. I work across the full stack — frontend through deployment. Where I've done this: DictateX — FastAPI backend with Whisper transcription, FHIR/TalkEHR integration, and automated SOAP note generation (live at qa.dictatex.ai) Azz Medical Associates — Flutter + Laravel + React.js appointment booking with real-time doctor availability (both stores + web) Capital Psychiatry Group — HIPAA-compliant telehealth app with video, scheduling, and insurance flows TeamMates, Hazir Hoon, Foodie Moodie — real-time features, live location, push notifications, VideoSDK Flutter (Bloc, Provider, GetX, MVVM) Laravel (REST APIs, Sanctum, Passport, Queues, Scheduler) FastAPI (Async APIs, Pydantic, SQLAlchemy) Node.js (Express, WebSockets) MySQL · PostgreSQL · MongoDB Firebase (Auth, Firestore, FCM) REST APIs · JWT/OAuth CI/CD Why Clients Work With Me ✅ End-to-end ownership — I've taken apps from wireframe to App Store approval, solo ✅ Real-time systems — chat, live location, video calls, and push notifications in production ✅ I test on real devices, not just simulators — before every client delivery ✅ Long-term mindset — most clients come back for Phase 2 ✅ HIPAA-compliant architecture — I've built two live telehealth apps with video, scheduling, and insurance flows I use AI tools (Claude, Cursor) daily — as a senior pair programmer, not a replacement for understanding. I test on real devices. I don't ship code I can't explain line by line.
