I've built simulated Dropbox and DocuSign environments for Microsoft Research to train and evaluate computer-use AI agents. Using Next.js, React, TypeScript, Zustand, IndexedDB, and localStorage, I created deterministic, data-first environments with machine-verifiable state assertions.

At Pentagon Studio, I architected a multi-tenant SaaS platform for 100+ organisations, including pricing configuration, secure Row-Level Security isolation, real-time Supabase collaboration, Stripe billing, and a Node.js browser-automation service supporting 40+ concurrent sessions. I also built an LLM-powered data-extraction pipeline that reduced manual research effort by 80% and improved p95 latency from 2.3 seconds to 380ms.

At HireQuotient, I led frontend architecture and a team of five engineers through a large-scale SaaS modernisation. Migrating to Vite and Redux Toolkit cut build time from six minutes to 35 seconds, reduced bundle size by 60%, and brought load time from 10 seconds to under 1.5 seconds.

Earlier at BigBinary, I built and scaled production applications from scratch, replacing no-code systems with custom engineering solutions. I enjoy solving complex performance, state-management, and product-engineering problems across frontend and backend systems.
