At Garage IT, I work on fintech and trading applications, owning frontend product surfaces from technical design through deployment and iteration. I focus on performance, reliability, and user experience.

I implemented Feature Sliced Design for a high-load international brokerage platform, reducing technical debt by 40%. I also developed reusable internal libraries and core UI solutions that increased feature delivery speed by 5x.

I engineered real-time trading dashboards with Pixi.js and Jotai that render complex financial visualizations at 120fps. I introduced screenshot testing and refined Docker and Playwright CI/CD pipelines, reducing visual regressions and deployment errors by 35%.

Earlier, at WebTechDevelopment, I helped transition a complex CRM from jQuery and Vanilla JS to Next.js, reducing technical debt by 25%. I enjoy mentoring developers and working with product, design, and backend teams to build maintainable, accessible software.
