About
I keep the systems that can't go down running.
I'm Bruno Fitas, a full-spectrum engineer. For years I've kept banks and other regulated systems up — where a failed audit, a security gap or an hour of downtime isn't an inconvenience, it's a serious problem — working across every layer, from the code to the architecture to the pager at 3am.
I started as a programmer and kept widening the lens: from application code to the infrastructure beneath it, the architecture around it, and the SRE practice that keeps it alive in production. I've been on every front — shipping features, designing platforms, writing the Terraform, and carrying the pager — so I see how a decision in one layer ripples through all the others.
I call it full-spectrum engineering. Covering that range used to take a whole team; AI changes the maths. By taking the grunt work — boilerplate, glue code, first drafts — AI frees a senior engineer to operate credibly across the entire stack, where the scarce part was never the typing, but the judgement. Anyone can build now; making it reliable, secure and survivable is the hard part — and that's the part I do.
In practice that means production-grade backends and APIs, cloud platforms designed and run properly, the Terraform that makes infrastructure repeatable, and the observability and alerting that tell you the truth before your users do. I've written companies' first SRE practices from scratch and kept banking systems up under real load, real incidents and real audits.
I'm calm under pressure and allergic to hype. I work alongside your engineers rather than around them — measuring first, designing for failure, and leaving things documented and owned by your team, not dependent on me. Bruno Fitas is the name behind the work; it's how I take on engagements and invoice.
How I work
A simple, transparent way to put a senior reliability engineer to work — on your terms.
- A free first call. You explain the problem, the system and the constraints — no charge, no commitment.
- I define the plan — the scope, the timeline, and what it will actually take to get there.
- I set up a Scrum board where you are the Product Owner. The backlog is yours.
- You decide the shape: from a few hours a month to full-time, scaled to what the work needs.
- You ask for what you need; I estimate it. A burn-down chart and regular check-ins — daily or weekly — keep the status honest and visible.
- You keep full control as PO — change direction, re-prioritise, scale up or down as the work demands.
In short: a dedicated senior reliability engineer, on tap — without the cost and burden of hiring one.
Principles
- Measure first. Opinions are cheap; I bring numbers and root causes before recommendations.
- Design for failure. Things break — the question is whether the system was built to survive it.
- Automate the toil. If a human is doing it repeatedly by hand, it's a bug waiting to happen.
- Leave it better than I found it — documented, owned by your team, and not dependent on me.
