SPECIALIZED IN

Performance Optimization, Accessibility & SEO, Frontend Security, and Scalable Architecture

ABOUT.

I build production web products for the moments that matter—when a page loads fast, a flow stays secure, and the UI feels effortless. My journey started with curiosity for how websites come to life, and it evolved into a craft: turning requirements into clean, maintainable software.

I’m strongest where systems meet performance. I build scalable frontend architecture, optimize for speed and SEO, and treat security as a first-class feature—especially in data-heavy and payment-related journeys.

I like working with teams that ship. From monorepos and micro-frontends to reliability improvements and Core Web Vitals tuning, I focus on outcomes that can be measured. A recent product relaunch helped drive SEO, performance, and conversion improvements—contributing to a 200% revenue increase. I collaborate closely with product, QA, and design to keep releases stable and systems improving over time.
