About

I build high-performance web applications that traders use in real time and that startups scale into products. Two internships at JPMorgan Chase and Citi. One SaaS product launched. One national hackathon final. Still shipping. I'm a full-stack engineer specializing in React, Next.js, and TypeScript — with a bias toward frontend systems that have to be fast, reliable, and visually precise. I've built everything from real-time market data dashboards at JPMorgan to a multi-tenant SaaS platform (Dion) with Stripe Connect payments, Prisma ORM, and PostgreSQL. Key achievements:- → JPMorgan Chase: Engineered full-stack apps on live stock price data feeds; improved code quality 25% and reduced delivery time 15% through standardized practices. → Citi India: Built a real-time stock market risk visualization tool in Java; designed a UML-modeled loan management system and evaluated ML approaches for credit risk. → Dion: Sole founder — designed and shipped a Next.js 14 SaaS website builder with Stripe Connect monetization, Prisma + PostgreSQL backend, and multi-tenant architecture. → Smart India Hackathon: Grand Finalist 2023 — top national selection out of thousands of teams. → PurpleTutor: Reduced admin panel overhead 50% through workflow optimization and feature development. I've shipped production code at two of the world's largest financial institutions before graduating. I've also operated as a founder — which means I care about both the engineering quality and the product outcome. I integrate AI APIs (OpenAI, LLMs) into user-facing products, not just experiment with them. What I'm looking for: Open to frontend, full-stack, or software engineering roles at product-led or AI-first companies — startups to FAANG. Especially interested in teams building developer tools, fintech infrastructure, or AI-integrated consumer products. 📍 Hyderabad, India · Open to remote · [email protected]
