Backend & Platform Engineer
I build Go services, real-time data systems and the infrastructure that keeps them running. Explore what I've built, the decisions behind it, and what the tests actually prove.

Computed from the published evidence snapshot at build time. Verifiable and self-reported claims are kept apart.
A coding-agent change is classified TASK_VERIFIED only when a test added or changed by that change fails on the base commit and passes with it; code-only changes, tests that already pass on the base, and tests that do not build on the base are not credited.
After the runner process is killed with SIGKILL mid-task, a second runner is refused while the lease is fresh, takes over once it is stale, marks the orphaned attempt rejected, keeps the killed attempt's edits, and completes the task from a resume pack rebuilt from the SQLite ledger.
An agent that follows injected instructions cannot weaken verification — a rewritten verification config is ignored because configuration is read from the base commit and the path is protected — and a host secret behind a planted symlink never reaches a context pack.
The container runner always builds engine arguments with no network, all capabilities dropped, no-new-privileges, a non-root user, read-only mounts where requested and tmpfs masks over secret paths, and refuses sensitive host mounts such as the home directory, ~/.ssh and the Docker socket.
A live production platform I architect and operate, and an open project where every claim can be checked against its tests.
Real-time data · backend platform
A live trading platform for real customers: market data streamed to several web applications, alongside purchase, wallet, payout and KYC workflows that must never double-charge or lose a change.

Coding agents overflow context on large repositories and report success because tests are green, even when no test exercises their change.
