What I'm looking for

I’m looking to build frontend systems for SaaS products where performance and clean architecture matter. I want to ship features end-to-end, collaborate closely with founders, and help create reliable experiences that don’t break.

I build frontend systems for SaaS products, not demos, not prototypes. I’ve shipped a resume builder with paying customers, a fintech dashboard with real trading data, an AI legal drafting tool, and a booking SaaS with Razorpay integration.

I have 3.5 years of React and Next.js across the full stack, and I understand finance well enough to write independent semiconductor analysis that ranks on Google. I care about performance, clean architecture, and shipping things that don’t break.

At Advor.ai, I’m the Lead Frontend Engineer building expert discovery, booking UI, and profile pages in Next.js + TypeScript, including secure escrow-style transaction handling. Previously, I built ResumeDone.ai end-to-end (Next.js frontend, Node.js + PostgreSQL backend, Stripe/PayPal checkout) and improved checkout conversion by A/B testing pricing layouts, while reducing LCP through code splitting, lazy loading, and asset optimization.
