Hey, I'm Pawel

A Senior Front-End Engineer with over 8 years of proven impact across React, TypeScript, and GraphQL — from early-stage products to platforms serving millions.

I've led frontend modernization efforts that cut page load times by up to 40%, migrated legacy monoliths to composable architectures, and shipped revenue-critical features across high-traffic e-commerce and enterprise platforms.

Today, I architect production-grade design systems, optimize rendering pipelines for sub-second interactions, and mentor engineering teams on frontend best practices — ensuring every interface I touch is fast, accessible, and built to scale.

I also leverage AI tools, prompt engineering, and context engineering to build AI-driven solutions that ship faster without sacrificing code quality — turning LLMs into a force multiplier for architecture, code generation, and automated testing workflows.

Looking for a senior engineer who ships with precision and owns outcomes? Let's talk.
