Hi there, I am Owais Ahmed, a Full-stack Next.js and MERN developer who builds software that ships, scales, and stays alive after launch. If you've dealt with developers who disappear after handoff, miss deadlines, or send you a half-working MVP , that's the problem I solve.
What I specifically deliver:
→ SaaS Platforms
Multi-tenancy, subscription billing (Stripe), role-based access control, analytics dashboards. I've built property management SaaS used by 1,200+ agents. I know what production SaaS actually requires — not just the happy path.
→ Investor-Ready MVPs
Not a prototype. Not a demo. A deployable, documented product your team can demo to investors and hand off to engineers. Built in weeks, not quarters.
→ AI-Powered Features
OpenAI API, LangChain, RAG pipelines integrated into real products, not bolted on as demos. Chatbots, document analysis, intelligent search, recommendation engines.
→ Mobile + Web, One Developer
React Native paired with Next.js. One codebase strategy, both platforms shipped and maintained by the same person. No coordination overhead.
→ APIs & Integrations
REST APIs, GraphQL, Stripe, Firebase, AWS, third-party webhooks. Clean, versioned, documented so your team isn't guessing how anything works six months later.
My code comes with:
Documentation your team can actually read. Tests that catch regressions. Architecturally, your next developer won't curse you for inheriting.
Working on a SaaS product, an MVP, or need AI built into something real? Invite me to your post — I'll come back with a specific 3-point plan for your project, not a generic pitch.
Tech Stack:
Frontend → Next.js, React.js, TypeScript, Tailwind CSS
Backend → Node.js, Express.js, NestJS, Django, FastAPI
Database → PostgreSQL, MongoDB, MySQL, Supabase, Firebase
Infra → AWS, Docker, Vercel, CI/CD
AI → OpenAI API, LangChain, RAG
Expertise: Full-Stack Developer | Next.js Developer | MERN Stack Developer | React.js Developer | Node.js Developer | SaaS Developer | MVP Developer | AI Integration Developer | REST API Developer | GraphQL Developer | FastAPI Developer | Django Developer | React Native Developer | Stripe Integration | PostgreSQL Developer | MongoDB Developer | TypeScript Developer | AWS Developer | NestJS Developer | Admin Dashboard Developer | Multi-Tenant SaaS | OpenAI API Developer | AI-Powered Web Apps | Backend Developer | Full-Stack React Developer
