What I'm looking for

I'm looking to lead frontend architecture and build scalable, accessible UI systems, while mentoring engineers and improving delivery speed, performance, and product quality.

At Synechron Technologies, I own frontend architecture for enterprise React and TypeScript products, turning Figma designs into accessible production interfaces. I built a Storybook-based component library and micro-frontend architecture used across 3+ product lines, reducing cross-team delivery time by about 25% and page load times by up to 25%.

Across Webonise Lab, Straviso, VT Fintech, and 9.9 Group, I've delivered scalable web interfaces, financial applications, and product features while improving performance, building reusable UI components, and mentoring engineers. I enjoy translating product and design requirements into reliable, high-quality frontend systems using React, Next.js, TypeScript, testing, and AI-assisted development workflows.
