Building Reliable Product Systems From 0 to 1
Front-End Engineer with 3+ years of experience building production web and mobile applications using React, TypeScript, and Next.js.
I focus on component architecture, reusable design systems, performance optimization, and test coverage across unit, integration, and E2E testing. Most recently the sole Front-End Engineer at Didit, where I owned frontend architecture end to end — from a real-time analytics dashboard to a client-facing identity verification product used across 220+ countries, integrating REST APIs and collaborating closely with Product, Design, and Backend teams. Comfortable with AI-assisted development tools like GitHub Copilot and Claude Code as part of a modern workflow, and experienced with CI/CD, Docker, and AWS. I'm persistent, a quick learner, and I like solving problems with simple, scalable solutions.
