I fix the backend bugs that threaten revenue and sleep for B2B SaaS companies between $3M and $50M ARR.
What I resolve:
- Payment race conditions — failed Stripe webhooks, double-charges, idempotency failures
- Data corruption — broken migrations, constraint violations, silent data loss
- Auth deadlocks — login failures, session edge cases, permission bugs under load
- N+1 query disasters — dashboards that timeout, APIs that crawl at scale
How it works:
- Send me a Loom of the bug and a brief on your stack
- I return a clear diagnostic + fixed-price quote within 24 hours
- You get a working system — plus a post-mortem doc your team can keep
