About

I build web products that people actually want to use. As a full-stack developer with 3+ years of experience in fintech and SaaS, I specialize in React.js, Next.js, Node.js, TypeScript, Java, and GenAI — crafting performant, scalable applications from the ground up. Some highlights from my work: → Raised new user retention from 35% to 51% at Preplaced through a full technical redesign and strategic leadership. → Led admin and report management system development at Finnspire for banking clients, delivering on complex compliance and UX requirements. → Built a following of 25,000+ sharing actionable content on frontend best practices, scalable architecture, and AI tooling. Beyond shipping code, I care deeply about the people in this industry. I've mentored developers who've gone on to join Google, Oracle, Digit Insurance, CME Group, EY, Virtusa, Groww, and more — and that's something I'm genuinely proud of. Whether it's architecting a greenfield product, untangling a legacy codebase, or helping a junior dev land their first role — I'm energized by the full spectrum of what this work involves. If you're building in fintech, AI, or high-growth SaaS and want a collaborator who brings both technical depth and product thinking — let's talk.
