As a Senior Full Stack Developer, I’m usually brought in for MVP builds, product rebuilds, and “this is breaking in production” moments. That’s the difference between hiring a Senior Full Stack Developer and hiring someone who only ships features. 👨‍💻 Senior Full Stack Developer (10+ years) focused on SaaS and MVP builds 🚀 I build from idea to production, with clean architecture, your team can maintain ✔ Often brought in by founders for MVP launches, rebuilds 🤝 I work like a product partner, clear trade-offs, no BS 𝗛𝗲𝗿𝗲’𝘀 𝘄𝗵𝗮𝘁 𝗜 𝗱𝗼: 1. Full-Stack Development 🔹 I take your idea and turn it into a production-ready MVP or SaaS product, end to end 🔹 You get clean code, fast delivery, and documentation your team can actually use 2. Front-end (React, Next.js, TailwindCSS) 🔹 Dashboards and product UIs that feel fast and don’t fall apart as you grow 🔹 SSR and performance work to keep load times down and UX smooth 3. Back-End (Node.js, Next.js, Express.js, Python) 🔹 APIs, auth, permissions, and business logic built for real-world usage 🔹 Background jobs, queues, and webhooks that stay stable when requirements change 4. Database (PostgreSQL, Prisma, Drizzle, Redis) 🔹 Database design, migrations, and query tuning for production performance 🔹 A clean data layer with Prisma or Drizzle, and Redis caching when it’s worth it 5. Cloud (AWS, Azure, Vercel) 🔹 Reliable deployments with clean environments and predictable releases 🔹 AWS when you need real control, Vercel/Railway/Render when you need speed and iteration 6. Software Architecture 🔹 I turn founder specs into a clear technical plan your team can execute 🔹 I make the trade-offs early so you don’t pay for them later with rewrites 𝗖𝗼𝗺𝗺𝗼𝗻 𝗽𝗿𝗼𝗷𝗲𝗰𝘁𝘀 𝗜 𝗵𝗮𝗻𝗱𝗹𝗲 1. SaaS product development (A → Z ownership) 2. MVP builds with Next.js and TypeScript under real production constraints 3. Backend systems with Node.js, Express.js,Nest.js, Python, (auth, APIs, business logic) 4. PostgreSQL and Redis performance fixes and data modeling 5. Background jobs, queues, and async workflows 6. AWS deployments and production stabilization 7. Debugging slow, breaking, or unreliable systems 8. Codebase cleanup: refactors, structure, release safety 9. Technical consultation before you build the wrong thing in your SaaS Tech Stack I use ✅ JavaScript, React, Next.js, TypeScript, Tailwind CSS ✅ Node.js, Express.js, NestJS, Python ✅ PostgreSQL, Redis ✅ Prisma ORM, Drizzle ORM ✅ AWS (Certified), Azure (Certified), Vercel, Supabase, Neon ✅ Git, production-grade workflows ✅ AI based workflows (Cursor, Claude, Co-pilot) When we work together, I will make sure your MVP is built the right way: clean code, strong architecture, and a solid foundation your team can maintain.
