Sumeet Haldar

Software Engineer

Driven by purpose, grounded in precision and built for production.

About

I'm a developer passionate about building scalable backend systems and real-time data pipelines. I enjoy solving complex problems where data structures and algorithms are key. Beyond scalable systems, I bring ideas to life with pixel-perfect, production-ready user interfaces.

Currently, I'm a Software Engineer at Equinix, where I focus on building robust infrastructure and real-time services. I design and maintain critical components that deliver reliable, scalable cloud solutions powering our global platform.

I enjoy playing BGMI and cricket in my free time, as they help me relax, stay sharp, and maintain a healthy balance between focus and fun.
