About
I'm a Full Stack Software Engineer based in New Delhi, India, with 2.5+ years of experience building scalable web applications, distributed systems, and cloud-native infrastructure — from backend architecture to intuitive user interfaces.
I've worked across broadband, pharma, and ed-tech domains, building high-performance search platforms, serverless ETL pipelines, analytics dashboards, AI-powered developer tools, and enterprise admin systems. My work includes scaling services from 20 to 3,000 requests per second, reducing infrastructure costs by 70%, and delivering products used by thousands of daily active users.
Outside of work, I build side projects to explore new technologies, sharpen my engineering skills, and turn ideas into production-ready products. I've launched 15+ projects and enjoy solving real-world problems through software.
