- Senior Full Stack Developer at CIBC (Toronto) since March 2026.
- Learning focus: Kubernetes (CKAD track) and agentic-AI systems — public lab repos will appear here as they ship.
- orbitdb/go-orbitdb: authored 194 of 201 commits through 15 merged PRs (#2-#16, 6 Nov - 5 Dec 2024): identities and keystore, log/entry with CID generation, modular storage and IPFS block storage, core database with tests, orbit-sync, and the Go CI workflow.
- CNSim (York University, cmg-york): extended the open-source Java consensus-network simulator with Bitcoin protocol behaviour (malicious-node attacks, hashpower changes) and a Transaction Finality metric; 33 commits across cnsim, cnsim-bitcoin and cnsim-engine (12 shared pre-split history, 21 new in Dec 2025 - Jan 2026, continued after graduation). MSc thesis: Simulation-based Evaluation of Transaction Finality in Bitcoin using CNSim.
- dtg2sim / RLGen / mx2dtx (cmg-york): research tooling for goal-model-driven simulation and RL environment generation; 17 commits in dtg2sim (which absorbed the 4 RLGen commits) and 2 in mx2dtx, top contributor on dtg2sim and RLGen (May 2025).
