About Me

Software Engineer with 5+ years of hands-on experience building production-grade backend systems, REST APIs, and cloud-deployed applications. Founder of Galaxyswift, an MSME-registered software firm in Coimbatore.

I have a ME in Computer Science (Big Data Analytics) from College of Engineering, Guindy - Anna University, with deep coursework in distributed systems, NLP, transformer architectures, and machine learning. Currently completing an MBA in Business Analytics from SRM and upskilling in DSA and system design at Scaler Academy.

I enjoy building things that work reliably at scale - whether that's a backend API handling thousands of requests or a locally-running AI system that needs zero cloud dependency.
