Engineer. Product Thinker. Builder.

Vaibhav Selkar

I transitioned from hardware and consumer product development to building scalable SaaS platforms. My journey combines mechanical engineering fundamentals with software architecture—understanding how to take ideas from concept to production at scale.

At Sanghamitra, I own the full software development lifecycle. From gathering product requirements and architecting backend systems to shipping features and driving adoption, I've learned to make data-informed decisions that move the needle on metrics that matter.

My technical toolkit spans Node.js and Express for backend architecture, React for frontend experiences, and Python with Flask for AI integration. I'm obsessed with performance optimization, reliable infrastructure, and building products that users actually love.
