About

Driven by a passion for solving problems, I build clean, scalable, and reliable backend systems. My experience spans high-impact fintech products across India, UAE, Saudi Arabia, and the US, designing payment flows, integrating banking systems, and optimizing performance under real-world constraints. I care about writing thoughtful code, continuous learning, and delivering products that create meaningful impact. ⚙️ I thrive in teams that value clarity, ownership, and collaboration. Working with people who challenge ideas and push for excellence has played a key role in my growth. 🤝 Outside work, I enjoy powerlifting, go-karting, and mindful walks. 🚗🌿
