Job Success
New Delhi, India - 11:07 am local time
With 50+ projects delivered across web, mobile, SaaS, and AI-powered products, I focus on one thing: shipping fast without errors. Not demos. Not half-built apps. Real products that users can actually use. My clients return because I deliver fast, communicate clearly, and handle the technical stress so they can focus on their business.
Whether you’re launching an MVP, scaling an existing product, or integrating AI into your workflow, I take full ownership of the technical side so you can focus on growth.
What Working With Me Looks Like
⦁ Clear scope, clear pricing, no surprises
⦁ Fast MVP delivery with production-quality code
⦁ Minimal meetings, smooth communication
⦁ Scalable architecture from day one
⦁ Reliable post-launch support and bug fixes
What sets me apart:
⦁ Speed without shortcuts: Live MVPs in 1-2 weeks, not months
⦁ 6 months free technical support after delivery (not common on Upwork)
⦁ Full-stack capability: I handle frontend, backend, databases, APIs, and AI—no need to hire multiple developers
⦁ Built for scale: Your app won't break when you grow
Recent wins:
⦁ Built and launched a B2B live e-commerce platform (Next.js 15) with real-time video streaming, live chat, seller leaderboards, and admin analytics — architected to handle 10,000+ concurrent users on AWS.
⦁ Delivered a high-performance financial & scientific calculation platform with dynamic charts, markdown editor, and modular calculators — shipped as a fast, SEO-optimized SPA with zero backend dependency.
⦁ Developed a premium global business marketing website using Next.js + Three.js, featuring real-time 3D globe visualization, GSAP animations, and glassmorphism UI to establish instant trust with enterprise clients.
I build systems that grow with your business, not projects that need rewriting after launch.
Core Services
⦁ MVP Development (Web & Mobile)
⦁ Full Stack Development (React, Next.js, Node)
⦁ Mobile Apps (React Native)
⦁ Custom Software & APIs
⦁ AI Integrations (OpenAI, RAG, Automation)
Tech I work with:
⦁ Frontend: React, Next.js, React Native, Flutter, TailwindCSS
⦁ Backend: Node.js, Express, MongoDB, PostgreSQL, Firebase, AWS
⦁ AI: OpenAI API, RAG, custom chatbots, image/video generation
If it needs to be built, shipped, and scaled — I handle it end to end.
Why Clients Choose Me
⦁ 50+ real-world projects delivered
⦁ 3+ years building production systems
⦁ Strong product thinking — not just coding
⦁ Quick response time (within hours)
⦁ Long-term partnership mindset
I don’t disappear after delivery. I support, optimize, and improve.
