- Own the self-serve Report Builder end to end — the Angular 20 UI and the Cube.js semantic layer behind it — shipping new data sources, calculated fields, filtering and export paths for multi-tenant customers
- Model and extend a 73-cube Cube.js semantic layer over a dbt-built multi-tenant PostgreSQL warehouse; its member metadata drives both the AI copilot's SQL generation and the report-builder field pickers
- Profiled the report builder's client-side aggregation: grid-state reads cut from 800,000 to 1 per pass and formula evaluations by ~45 %, taking 100,000-row reports from a tab crash to 2.8 s (an optimisation study, verified with a golden-master harness)
- Shipped the React 19 + WebSocket AI copilot's report-building surface — multi-table artifacts, cancellation, shared-credit display and recovery when a streamed turn never replies
- Hardened multi-tenant analytics correctness (guarded SQL casts, qualified join columns, org-hierarchy counts) and extended a TypeScript/Express + MongoDB Tally ERP sync broker
- Built EU/US multi-region bundles and CI deploys; authored 188 Jasmine/Karma spec files (~1,970 cases)
Upstream work on OpenFeature — the CNCF feature-flagging standard — on go-git, the pure-Go implementation of Git, and in the Argo ecosystem.
| Project | What I work on | Contributions |
|---|---|---|
| open-feature/go-sdk | Spec conformance in flag evaluation, hooks and error handling | PRs → |
| open-feature/spec | Pinning down behaviour the SDKs currently read two ways | PRs → |
| go-git/go-git | Remote and shallow-clone correctness, proven against upstream Git | PRs → |
| argoproj/argo-ui | Component behaviour traced from Argo CD bug reports, fixed once for Argo CD, Workflows and Rollouts | PRs → |
Every fix starts as a reproduction against the public API at a known commit, with the test proven to fail without it — for example go-sdk#566, where ObjectValueDetails returned Go's zero value on an abnormal evaluation instead of the default the caller passed in.
