Senior engineering for fintech & AI products
Make Cursor- and Claude-shipped code production-ready — security, evals, cost, and observability — for B2B SaaS teams that moved fast and now need to ship safely.
What we focus on
Security & secrets hygiene
Credential leaks, vibe-coded auth, tenancy gaps, and the blast radius of agent tool permissions — before production finds them.
Evals & failure modes
RAG and agents that shipped without evals. We surface what breaks under real inputs and how the system fails gracefully — or doesn’t.
Cost & observability
Token spend, caching, runaway usage paths, and the telemetry you need to see problems before customers do.
Hands-on remediation
Optional 30-day retainer after discovery: senior, hands-on fixes with your team — not junior vibe-coding tickets.
Who it’s for
B2B SaaS founders
You shipped with Cursor or Claude and need a clear path to production-ready.
Engineering leads
Your team moved fast; you need senior eyes on security, evals, and cost before scale.
Teams that vibe-coded to prod
CI is green. Production still isn’t. You want an honest audit, not a pitch deck.
Startups launching products
A quality and reliability ally when elevating systems from demo to durable.
How it works
Discovery
A paid 5-day review of your Cursor/Claude-shipped repo — what will break in production, ranked by risk.
Report
A clear findings report across security, evals, cost, and observability — actionable, not theatrical.
Optional retainer
A 30-day remediation retainer to fix the highest-risk issues with you, hands-on.
