Batho Makgau — SaaS Backend Surgeon

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:

1. Send me a Loom of the bug and a brief on your stack
2. I return a clear diagnostic + fixed-price quote within 24 hours
3. You get a working system — plus a post-mortem doc your team can keep

Stack: Node.js · PostgreSQL · Supabase · Stripe · Next.js · Redis
