Profile
“Clarity over cleverness. Systems that scale. Accessibility as a requirement, not an afterthought.”
Senior frontend engineer with 10+ years of experience building scalable web applications. Specialized in React ecosystems, TypeScript, platform thinking, and long-term system sustainability.
Strong advocate for codebases that stay understandable over time, with accessible interfaces, thoughtful review culture, and architecture decisions that support product evolution instead of fighting it.
AI & Automation
Applies AI tooling daily as a force multiplier — not just for code generation, but for architectural exploration, automated code review, and building internal DX tools that remove friction from development. Iterates across multiple LLMs (Claude, GPT, Gemini) to pressure-test decisions and surface blind spots. Treats AI output with the same scrutiny as any PR — validating against established standards before shipping.
