Why "38bits"?
In 1952, IBM shipped the IBM 701 — the first large-scale electronic scientific computer in history. Its accumulator had 36 bits.
But the engineers added 2 more.
Not because the spec demanded it. Not because customers asked. They added them because critical operations cannot tolerate overflow on the last digit. Those 2 bits never needed to exist — but they're what separated sufficient from exceptional.
That's the name. That's the principle.
What we do
We build software for systems that can't fail:
- Smart contracts on Solana with Anchor + Rust
- Zero-trust security from the first commit
- APIs built for real load — observability, rate limiting, CI/CD with production-grade tests
- Independent code review with seniority — not a trainee reviewing the senior
Brazilian fintechs. DeFi protocols. Backends where downtime has a real dollar cost.
Principles we don't negotiate
- Senior in every critical decision. Not a junior executing while a senior reviews once. Real seniority shapes architecture, not just approves PRs.
- Zero-trust from commit #1. Auth, rate limiting, observability, vulnerability scanning — not bolted on after the first incident.
- Tests in production-real conditions. Concurrency, load, edge cases. Local with happy paths is not enough.
- Living documentation. Decisions get written. Tradeoffs get documented. If it's not written, it didn't happen.
- Defined SLA + SLO. Not "we'll do our best" — measurable commitments with consequences.
The customer we want
CTOs, engineering heads, technical founders running:
- Fintech (PIX, payment processors, exchanges)
- DeFi protocols pre-audit
- Critical infrastructure where downtime ≠ negotiable
- Pre-launch systems that can't afford a bad first impression
If you're hunting for the cheapest provider, we're not it.
If you've been burned by a code review that didn't catch what it should have — we want to talk.
What's next here
We're going to share:
- War stories from production (anonymized)
- Stack decisions and tradeoffs
- Solana/Rust patterns we actually use
- Security findings worth sharing
- How we think about senioridade in code review
38bits — software where the 2 extra bits matter.
