What I'm looking for

I am seeking frontend or full-stack roles where I can build scalable, user-centric products, collaborate with cross-functional teams, and grow technically in a product-driven environment.

I am a frontend developer with 4+ years building customer-focused products across E-commerce, FinTech, HealthTech, AgricTech, EdTech and SaaS using React, Next.js, React Native and modern JavaScript frameworks.

I have designed and developed scalable, high-performance user interfaces, integrated frontend components with backend services, and built backend APIs with Node.js and MongoDB while improving development processes and workflows.

I collaborate effectively with cross-functional teams, contribute to product design and QA (unit and integration tests), and deliver reliable, responsive applications optimized for performance and real-world usage.
