I build agentic systems that catch fraud before it ships — LLMs orchestrated through deterministic graphs, grounded in policy, and observable enough to put on call.
11 years in. Java & distributed systems → Python & ML platforms → now full-time on agent infrastructure.

A workbench for prompt iteration. Edit a prompt, sweep it across a real dataset, let a judge model score the result, accept the suggested edits, promote the winner. The same engine runs in CI to gate regressions. TypeScript · v2.2.1 · single-file binary, local-first |
Autonomous open-source contribution plugin for Claude Code. Orchestrates six specialist agents — issue selection, repo profiling, planning, building, merge-probability scoring, comment resolution — without hand-holding. Claude Code plugin · v0.4.1 · seven merged releases |

- Benchmarks over vibes. Datastores picked with IOPS and
$/hr; LLM routes picked with eval numbers. - Security is the first tenet, not the last. Name the threats, name the controls.
- Entity thinking. If you're debugging individual events, you're already behind the fraud ring.
