Claim
Reviewed and fixed the money and scale-out paths of Fluxa's TypeScript (Fastify) backend in 17 commits: every balance change writes a ledger entry in the same transaction, deposit and payment confirmation use a compare-and-set so concurrent confirms cannot double-credit, N+1 queries, missing timeouts, unbounded reads and missing indexes are fixed, and games fail closed when Redis is unavailable.

Source
A product I own. Its repositories are private and cannot be published. So this claim is self-reported: it stops at Implemented and links to no artifacts.
Limitations
- LIMITThe fixes were not load-tested by me; the repository's k6 scripts are the other engineer's and their results are not recorded.
- LIMITBuilt with one other engineer; about a third of the commits are mine.
- Source code: private repository.

Built Fluxa's historical candle pipeline: a BullMQ job queue that downloads Dukascopy data in monthly chunks, inserts idempotently, resumes from its last checkpoint after a retry, can be cancelled, and runs in a separate worker process so it never blocks the live price stream.
