Full Stack Developer

I’m a Full Stack Developer with over 7 years of experience building end-to-end web applications—from crafting seamless user interfaces with React and Next.js to designing efficient, scalable backends with Node.js.

My work spans diverse domains, including secure online transactions and blockchain integrations. I thrive on problem-solving—turning complex challenges into clean, practical solutions.

Outside of code, I recharge by traveling, exploring nature, and spending time with my kid—my best source of inspiration.
