About me

I'm a Lead Software Architect from India, specializing in mobile applications and full-stack software development. I enjoy turning complex engineering challenges into efficient, scalable, and maintainable solutions.

My role involves guiding architecture and development while ensuring we clearly understand the problem, validate decisions with data, choose the right tools, and maintain strong code governance. This approach helps keep development and maintenance costs low. In fast-moving startup environments, I also contribute to strategic decision-making by helping prioritize the most impactful problems when time and resources are limited.
