I build tools that make AI/ML systems more reliable. Most AI demos are slick; most AI in production is messy — I like working in that gap, close enough to the real problem to build something that doesn't fall apart outside a notebook. Author of codehound, 29 PRs merged into AI, Python infrastructure, networking and IoT projects with a combined 400k+ stars.

Currently

An AST-based Python static analyzer — 104 checks, zero dependencies, CI on Python 3.9–3.12. Each check is distilled from a real bug found and fixed in a popular open-source project: fire-and-forget tasks that get garbage-collected mid-run, event-loop-blocking calls inside async functions, mutable default arguments, unclosed resources, and more. Several of the merged fixes below were surfaced by it. Try it on any GitHub repo or local folder at the playground — no install needed.

🔧 Open-source contributions

Real bug fixes across widely-used AI/ML and Python infrastructure repositories. One change shipped in a HuggingFace production release; one came from a founder's invitation to contribute (Future AGI).

Apache Maven
build tooling, Java
Four merges, all reviewed by @elharo. A test in the source plugin that asserted on the wrong path so it could never fail. A deprecated Maven 2 constant in the help plugin — the issue proposed replacing it with null, which would have emptied the metaversion and broken two-part coordinates, so the value stayed and the first tests for that method came with it. And a hash analyzer that computed and cached a jar's SHA-1 correctly but returned the stale null local instead of the new value, so every first-time lookup behaved as if the file couldn't be hashed. And the source plugin's aggregate goal, which silently did nothing on a non-POM project, now fails with a message naming the project and its packaging.

Celery · kombu
messaging for Celery
The SQS transport cached queue URLs, boto3 clients and its no-ack set at class level, so every Connection in a process shared them. Two connections to different AWS accounts that both used a queue called orders ended up sending to and polling whichever URL was cached first. Verified against a local SQS emulator with an integration test.
kombu #2676 · merged

pydantic · black
29k⭐ · 42k⭐
A bare isinstance(...) statement in pydantic's decorator collection that checked the wrong variable and discarded its result, turned into a real invariant. And two grammar-file handles in black's blib2to3 converter that were opened and never closed — found by codehound.
pydantic #13858 · black #5432 · merged

scapy · pymodbus
12.6k⭐ · 2.8k⭐
In pymodbus, every device identity shared one class-level dict, so creating any identity changed what a running Modbus server reported. The maintainer merged it within the hour: "one that have been on my list for a long time". In scapy, a missing tcpreplay surfaced as an UnboundLocalError instead of scapy's own "is it installed?" message.
pymodbus #3036 · scapy #5204 · merged

redis-py
14k⭐
utils.pipeline() ran execute() after a bare yield, so an exception inside the with block skipped it. After a watch() that leaked a real pooled connection on every failure.
redis-py #4345 · merged

Mercari
data pipeline, Java
Two Avro timestamp bugs on the JDBC path — timestamp-micros truncated to milliseconds, and a millis-to-micros conversion that scaled the wrong way — both silently corrupting sub-second data.
pipeline #119 · #122 · merged

Snipe-IT
PHP · asset mgmt
--force did not suppress a PHP-version prompt in ldap:troubleshoot, so the command hung in Docker where no one could answer it — the guard present on two neighbouring confirmations was missing on the third.
snipe-it #19514 · merged

palinode
memory store
Two memories whose opening lines matched derived the same filename, and the second silently overwrote the first — no error, and a receipt indistinguishable from a fresh save. Fixing the collision exposed a second bug the maintainer caught in review: a memory pushed onto a suffixed path climbed to a new suffix on every re-save, because the scan skipped occupied files without checking what was in them.
palinode #132 · merged
