About & Experience

Who I Am

Backend-focused Software Engineer with a builder's mindset — driven to take products from 0 → 1 and scale them into reliable, production-grade systems. I thrive in early-stage environments where speed, ownership, and clear thinking matter more than process.

I specialize in system design, data-intensive architectures, and event-driven systems. My core stack includes Node.js, Python, Java, SQL, BigQuery, Redshift, Kafka, and cloud infrastructure (GCP, AWS).

As Sr. Software Engineer at Osmos.ai, Pune, I focus on owning critical backend modules, translating business requirements into scalable technical specs, and delivering end-to-end solutions with minimal rework. I lead client-facing projects, handle end-to-end feature delivery including design, development, deployment, and monitoring.
