What I'm looking for

I seek frontend roles focused on high-scale user experiences, performance optimization, modern React/TypeScript stacks, and strong CI/CD practices, with opportunities to lead migrations and improve developer workflows.

I am a frontend engineer focused on building performant, scalable React and TypeScript applications for high-traffic platforms. I have driven migrations from ReScript and JavaScript to TypeScript, established development standards, and owned releases for products serving hundreds of thousands of users.

My work emphasizes real-time features, location accuracy, and robust CI/CD: I implemented high-accuracy geolocation for 10,000+ daily users, enabled GitOps CI/CD with ArgoCD for canary deployments, and built WebSocket-powered real-time communication systems. I also integrated A/B testing, dynamic CMS-backed content, and speech-to-text features to improve engagement and product iteration.

I deliver measurable performance improvements—raising Lighthouse scores from 56% to 94% and SEO from 68% to 98%—and prioritize developer experience through tech-stack upgrades, code ownership, and reliable deployment practices to reduce bugs and accelerate delivery.
