FIG. 1 — THE ENGINEER, BHUBANESWAR
I build the parts of software nobody notices until they break.
Three years of production backend work in Rust and Python across distributed systems, blockchain infrastructure and authentication architecture. I ran an auth service 10,000 people depended on daily, and this page loads from a platform I designed, built and operate alone. Web3 Foundation grant recipient, Polkadot Blockchain Academy graduate, and the kind of engineer who writes the documentation, runs the tech talk, and answers the pager. I teach a 110-hour Rust course, run a community of 100+ Rust developers, and believe boring, measurable reliability is the most underrated feature in software.
