Fieldwork
This is a selected record of systems I have entered, shaped, built, repaired, or carried into use. The domains change. The through-line is ownership across the boundary between a need and a working deployment.
Primary evidence
2026 / sanitized work sample
Private cloud and AI operations with dense configuration, permissions, async state, and costly mistakes.
Joined product and engineering concerns in one operational model, with review, evidence, recovery, and ownership visible.
2026 / public product
Creators need fast subtitles without learning a full editor or committing to another subscription.
Scoped and shipped the product loop across media processing, editing, payment, export, SEO, and support.
2026 / public product and open-source companion repos
People have recordings but need reusable slides, frames, documents, and subtitles without uploading private files.
Built a local-first browser pipeline, product surfaces, open core, export formats, and search-led acquisition.
2026 / public fork
A Feishu/Lark deployment failed inside a real proxy environment while surface-level status looked healthy.
Traced runtime behavior, isolated the routing bug, produced a narrow fix, and sent the evidence upstream.
Wider range
AI and agent systems
Designed a workbench around living documents, agents, jobs, run traces, and human editorial gates.
