Umesh S.

Full Stack AI SaaS Engineer | React Native | Next.js | Node | Supabase

I help founders turn ideas, AI-generated prototypes, and MVPs into secure, scalable products that are ready for real users. Over the years, I've built production-ready SaaS platforms, AI applications, mobile apps, CRMs, ERP systems, healthcare platforms, property management software, and consumer applications used by thousands of users. My focus is not just writing code. I help founders make the right technical decisions, improve architecture, ship faster, and build products that can grow without constant rewrites. What I work on: ➜ AI SaaS platforms ➜ React Native & Expo apps (iOS + Android) ➜ Next.js & React web applications ➜ Node.js APIs & backend architecture ➜ Supabase, PostgreSQL & MongoDB ➜ OpenAI, Claude, Gemini & AI integrations ➜ Stripe subscriptions & payment systems ➜ Authentication, RBAC & multi-tenant SaaS ➜ Lovable, Bolt.new, Replit, Base44 & AI-generated MVPs ➜ Production deployments, CI/CD & scaling AI Experience I build AI products using: ➜ OpenAI GPT ➜ Claude ➜ Gemini ➜ RAG & Vector Databases ➜ AI Memory ➜ Streaming Responses ➜ Prompt Engineering ➜ Tool Calling ➜ OCR & Document Processing ➜ AI Cost Optimization Selected Products ➜ FurCare AI AI-powered pet care platform with chat, image analysis, health tracking, subscriptions, and mobile apps. ➜ Pawpular Walk-to-earn social fitness platform with live step tracking, rewards, competitions, and React Native mobile apps. ➜ Field Operations Pro Enterprise ERP platform for field operations, task management, scheduling, reporting, and mobile workforce management. ➜ Vaistat Healthcare SaaS platform with patient management, appointments, telemedicine, medicine delivery, and admin dashboards. ➜ Gated Property management platform with resident portal, visitor management, payments, notifications, and role-based dashboards. How I work I move fast without compromising quality. AI tools like Claude Code, Cursor, Copilot, Lovable, Bolt, and Replit help accelerate development, but every feature is reviewed, tested, optimized, and production-ready before release. I believe in: ➜ Clean architecture ➜ Maintainable code ➜ Honest communication ➜ Weekly demos ➜ Long-term partnerships If you're building an AI SaaS, mobile app, internal platform, CRM, ERP, marketplace, or want to take an MVP to production, I'd be happy to discuss your project and recommend the most practical approach before writing a single line of code.
