I build AI features end to end: the model, the service that serves it, and the interface on top — prototype to production, without a handoff. Much of my work is local-first by default, so retrieval and inference run on your own infrastructure and customer data never leaves it. My fixes are merged into n8n and openclaw, mostly the unglamorous kind — a silent data-loss bug, a cross-platform breakage, a missing CI pipeline — each one pinned with a regression test. I'd rather ship what survives production than what demos well.
- Developing: maestro — an open-core orchestrator for multi-agent LLM workflows, self-hosted and bring-your-own-key
- Focus: Production RAG, MLOps, and applied ML
- Open to: Collaboration on scalable RAG / LLM systems

- P0 release blocker: OpenClaw installed but the managed Gateway never started for Windows users whose profile path holds non-ASCII characters outside the CJK range — the generated
.cmdlauncher was written in UTF-8, butcmd.exeparses batch files with the boot-time OEM code page. Fixed across 15 OEM code pages; verified on a Turkish host (ev-yiğit-öğün, ACP 1254 / OEMCP 857) going fromMODULE_NOT_FOUNDto a clean start, with byte-identical output on CJK hosts (PR #108967) - A compacted session's summary grew a copy of itself every cycle, burning tokens on each following turn: whenever a later split degraded, staged compaction re-added a summary chunk 0 already carried (occurrences 2 → 1 after the fix). Fixed in 14 source lines by keying the fallback on whether the oldest split degraded — the one signal the consumer actually asks for — with regression coverage at both layers (PR #109828)
- Every file an agent created on Windows came back lowercased — any name not already lowercase — so the import it had just written broke for all teammates on Linux and in CI; Turkish names like
İstanbul.mdcame back corrupted, not merely lowercased. The sandbox helper was returning a comparison key as a real path — fixed with a case-preserving normalizer, every boundary verdict proven unchanged (PR #109823) - Every truncated turn was billed by the provider but recorded as free — zero tokens, zero cost, and a
stopreason marking it successful, so nothing downstream could retry or warn and per-session accounting drifted low. Any answer hitting the output cap endsincomplete, and that event matched no terminal branch in the agent transport. Fixed by finalizing both terminal events through one canonical usage mapper shared with the package side (PR #109904) - A reply whose code fence opened with a long info string was dropped outright: the chunker reopened the block on every continuation with that full opening line while budgeting only the closing marker, so chunks ran past Discord's 2000-character limit and were rejected with HTTP 400. On a worst-case fence, 1534 chunks with 41 over the limit became 4 that all send, with the body intact instead of 41 of 1290 characters surviving (PR #110148)
- Invalid credentials took 7093ms and 4 requests to report; now 3ms and 1. The retry loop threw its non-retryable errors inside the
trywhosecatchtreats everything as a retryable network failure, swallowing its own classification. Rethrown as a distinct type, same message to the user (PR #110655) - Reef died permanently to relay rate limiting and had to be restarted by hand — a throttled startup failed the whole account, the supervisor's ten restarts each hit the same relay, and the retry traffic fed the throttling that caused it. Startup now shares the periodic reconcile's failure policy: the account comes up on the peer keys it already has and refreshes on the next interval (PR #110918)
- A rate-limited turn failed instead of simply waiting out the server's cooldown: when a 429 carried an unparseable
retry-after-ms, the validRetry-Aftersitting next to it was never read, so the client fell back to blind exponential backoff and burned its attempts inside the window. The two headers are ordered preferences, not alternatives — returning only on a successful parse restored that. Measured against a real socket, the retry gap went from 1016ms of blind backoff to the 3018ms the server asked for (PR #111353)

- Designed and prototyped the client-side RAG pipeline that gave AI intelligence briefs historical context — embeddings and cosine similarity running in a Web Worker over an IndexedDB vector store, so retrieval needs no server-side index. My prototype (PR #647) was reworked by the maintainer and shipped as PR #675

- Gave the project its first automated test run: CI until then only reviewed skill prose, never behavior — now pytest across Ubuntu and Windows plus vitest for the Pi extension, on every PR and push to master (PR #199)
- Running that suite on hosted runners exposed two latent cross-platform test failures — a Git Bash path-alias mismatch on Windows and Windows-shaped sanitizer vectors executing on POSIX. Fixed test-side, no production changes, and landed first so the CI PR could go green (PR #198)
- Made those runs reproducible: committed a lockfile for the Pi extension and switched the vitest job to
npm ci(PR #200)

- A shutdown during boot could wipe every recorded day of token usage, silently — cancel the consumer while it is still reading the file (Ctrl-C,
uvicorn --reload, a quick restart) andstop()force-flushes a cache that was never seeded, committing{}overtoken_usage.jsonthrough an atomicos.replace()with no backup and nothing logged. The window only opens for users who have history to lose. Pinned by a regression test and a positive control (PR #6220) - Cut one of three
nvidia-smispawns at startup and half of those per/modelsrequest — 40% off the measured probe time: a CUDA guard re-ran a query that already returns cleanly without a driver (PR #6204)
