Distributed Auth Service in Rust
Authentication microservice 10,000 people depended on daily. Biscuit capability tokens, session management, distributed rate limiting, DDoS protection. Ran in production for three years.
AI & Backend Engineer · Python / Rust / MLAI AUTOMATION @ TCS
I build the parts of software nobody notices until they break — now pointed at AI systems.

Three years of production backend work in Rust and Python across distributed systems, blockchain infrastructure and authentication architecture — and now an AI Automation Engineer at TCS, applying machine learning and LLMs to real workflows.
I ran an auth service 10,000 people depended on daily, and I design, build and operate two learning platforms solo, including ai.coredump.digital. Web3 Foundation grant recipient and Polkadot Blockchain Academy graduate. I believe boring, measurable reliability is the most underrated feature in software — and it matters more once a model is in the loop.
01 / Selected Work
Authentication microservice 10,000 people depended on daily. Biscuit capability tokens, session management, distributed rate limiting, DDoS protection. Ran in production for three years.
Free Rust learning platform: auto-graded exercises on the real compiler, 32 topic tracks, daily interview questions, a debug arena, and a curated board of Rust jobs. Designed, built and operated solo. Featured in Rust Bytes #122.
Sister platform for learning Python, ML and AI. Python runs in the browser via Pyodide with auto-graded exercises and a spaced-repetition review that brings missed questions back until they stick — plus quizzes, timed drills, and an AI/ML job board.
On-chain match predictions and team loyalty for football fans. Pick a national team to mint a non-transferable Fan Card, lock score predictions before kickoff, and post permanent chants to a team wall; a custom ESPN oracle settles results permissionlessly and a leaderboard ranks fanbases. No backend — every record is a Solana account. Anchor program (7 instructions) + Next.js. Built for DEV's Weekend Challenge, Best Use of Solana.
The x402 HTTP payment protocol across Solana and Polkadot: pay-per-request API monetization with automatic transaction signing and on-chain settlement. Axum API server, a Subxt-powered facilitator verifying transactions on chain, and a frontend client.
A decentralized dead man's switch on Solana: assets transfer automatically to designated beneficiaries after a period of wallet inactivity. Anchor program with on-chain state management, a frontend, and a full test suite.
A blockchain economic model enabling gasless transactions through stake-based credits, designed at the Polkadot Blockchain Academy. Runtime logic for credit accumulation, transaction validation and state transitions in Substrate.
