Software engineer at The Squa.re who migrated legacy pages to Next.js, cutting LCP from 4s to 1.5s.

At The Squa.re, I led the migration of legacy Python/Jinja pages to Next.js and React, cutting LCP from 4s to 1.5s. I also built the supplier portal with typed REST API integrations, JWT cookie-based authentication, and supplier onboarding flows.

Previously, at MiM-Essay (MentR-Me & Kraya AI), I led frontend architecture and major framework migrations that improved Core Web Vitals by 40%. I built AI-powered essay evaluation and chat interfaces using the OpenAI API, and developed Node.js workflows for WhatsApp automation and lead capture.
