I build AI agents, smart-contract systems and developer tools. Most of what's below is deployed, so you can try it. You can reach me at omkarrane0934@gmail.com, on LinkedIn or on X.
An investigation agent on FalkorDB. Given a fraud alert, it works out the few accounts to freeze so no route for stolen money is left, then checks the plan on a copy of the graph before a person approves it. A minimum cut needs a median of 1 account where a most-recent-recipients rule needs 3, and a verified plan takes a median of 0.27 s. It also caught FalkorDB returning a wrong max-flow answer (300 against the true 453) and gained a verified repair path. Live demo.
A two-player card duel on Monad testnet. Both fighters seal a move in secret and a contract resolves the turn, so no one can see or change a move afterwards. Fighters are NFTs whose records only the arena contract can write. Five contracts are deployed and source-verified. Live demo.
Milestone escrow for agreements that can't be gamed. Terms are signed by both sides as a hash, and the vault is tested against attacker contracts for reentrancy, forced ETH and rejecting recipients. Deployed on MST testnet. Live demo.
A tamper-evident container that locks at origin, watches itself in transit and settles payment on-chain by rules fixed before dispatch. A clean delivery pays the seller. A tamper refunds the buyer and slashes the courier's bond. ESP32-S3 sensors feed an escrow contract on MST testnet. Live demo.
A lightweight Windows storage visualizer and cache cleaner in native PowerShell and WPF. It has 36 cleanup targets, no external dependencies and a fail-closed safety engine.
Evidence-driven hiring. ADA, a multi-agent assistant, builds a model of each candidate from their actual work (GitHub, projects, interviews) and gives recommendations where every score is explainable. Live demo.
I've also built Signify_, a sign language tutor, CT-Flow, a cybersecurity copilot, Veyra, an intelligent companion, and Kevin, a desktop companion in C++.
