Turso savepoint rollback fix
Found and fixed a savepoint rollback/cache invalidation correctness bug, added deterministic simulator coverage, and received the project reward.
View PR #6626Open source reliability and bug fixing
I turn hard-to-reproduce bugs into small, reviewed fixes.
I help database, devtool, and AI infrastructure teams reproduce correctness issues, write regression tests, fix failing CI, and submit focused pull requests that maintainers can review quickly.
Proof of work
Real merged work matters more than a list of tools. These examples show correctness debugging, test coverage, production guards, and product implementation across active open-source projects.
Turso DETACH transaction guard
Prevented DETACH on databases with active transactions and added SQL regression tests for read and write transaction behavior.
View PR #6521XMem API key hardening
Added API key scopes, expiry, org/project bindings, validation checks, and production storage guards with test coverage.
View PR #176Rustchain explorer and faucet
Built a unified Keeper Explorer and Faucet interface with a Flask backend and deployment-ready UI work. Received a 1,000 RST project reward.

I am best suited for small, high-leverage engineering tasks where a team needs evidence, a reproducible case, and a fix that does not create extra review burden.
Bug reproduction and fixes
I reduce vague reports into minimal reproducers, compare expected behavior, and ship small fixes with regression tests.
Database correctness QA
Targeted checks for rollback, savepoints, schema changes, indexes, constraints, crash/reopen behavior, and integrity checks.
CI and test rescue
I debug failing checks, isolate flaky tests, clean test assumptions, and make the change easy for maintainers to verify.
Working style
The goal is not to send a big patch. The goal is to make the bug obvious, make the fix reviewable, and leave maintainers with less work than before.
Reproduce
Start with the smallest failing case I can prove locally.
Compare
Use reference behavior, logs, CI output, or documentation to pin down expected behavior.
Explain
Write the root cause in plain language before changing too much code.
Fix
Keep the patch small, direct, and aligned with the existing codebase.
Verify
Add a test that fails before the fix and passes after it.
Fixed-scope packages
Simple scopes make the work easy to evaluate. Pricing depends on repository size, setup difficulty, and whether the target is public or private.
