Lead Frontend Software Engineer with 8+ years of experience building and scaling user-facing web applications across startups and enterprise environments.

Strong expertise in React, Next.js, and TypeScript, with a focus on clean UI architecture, reusable components, performance, and developer experience. I’ve led frontend design and development for multiple products from concept to launch, partnering closely with product, design, data science, and backend teams in Agile environments.

My work includes launching AI-driven products, building real-time conversational interfaces, creating data-heavy dashboards, and improving user experience through experimentation and A/B testing. I enjoy owning frontend systems end-to-end — from architecture decisions and testing setup to production delivery.

I’m particularly interested in solving complex problems at scale, and building frontend platforms that are reliable, maintainable, and delightful to use.
