What I'm looking for

I’m looking for remote opportunities where I can build scalable React/React Native frontends, contribute to full-stack delivery, and provide technical leadership—partnering with product and engineering to ship enterprise-grade experiences.

I’m a Senior Front-End Engineer with 7+ years building scalable web and mobile applications using React, React Native, TypeScript, and JavaScript. I design modern user interfaces, integrate REST APIs, and apply frontend best practices to deliver enterprise solutions.

At Tata Consultancy Services, I led and mentored a team of 5 developers through technical guidance, code reviews, and architectural direction. I developed complex UIs, built reusable component libraries, and collaborated with product owners and Scrum Masters to shape technical roadmaps and estimates.

My work also spans secure, enterprise systems from NXP Semiconductors as a React Subject Matter Expert (SME). Through freelance projects, I built end-to-end features across mobile and backend workflows— including offline-first capabilities with WatermelonDB and REST APIs using Python/FastAPI.

I enjoy modernizing platforms, from upgrades and vulnerability remediation to React migrations and AEM Headless integrations. I bring technical leadership, quality focus, and hands-on delivery to roles where I can help teams ship reliable, scalable products.
