Senior cloud infrastructure & data consulting
Infrastructure that became a bottleneck, not an advantage.
If your AWS bill grows faster than revenue, month-end reports crash production, or on-call is just firefighting — that's not "just ops". It's accumulated technical debt. Cerradum steps in, diagnoses it, and fixes it, with senior engineering end to end.
AWS DevOps Professional · Terraform Associate · KCNA — you talk directly to the person who implements, no account manager in between.
Does this sound like you?
If two of these ring a bell, it's worth 30 minutes.
Your AWS bill keeps climbing
And no one on the team can explain exactly why, service by service.
Reports crash production
A heavy month-end query and a customer-facing slowdown at the same time.
Terraform became technical debt
The infrastructure only lives in one person's head — who might leave tomorrow.
On-call fights fires, not engineering
No SLOs, no real observability, no time to prevent the next incident.
Three fronts. One engineering discipline.
Infrastructure, data and operations treated as one platform — so the bill, the analytics and on-call stop being a problem.
Cloud Infrastructure
AWS · Kubernetes · Terraform
Fully code-defined environments — no more clicking through the console. You know what's running, why it costs what it costs, and any engineer can understand it in an afternoon.
Data Platform
Kafka · Iceberg · StarRocks
Lakehouse and streaming to get analytics off production for good. Your month-end query stops competing with the customer checkout.
Reliability & Operations
SRE · FinOps · Observability
Real SLOs, observability and FinOps. Fewer 3am pages, more predictability — and a cloud bill that makes sense.
No fixed packages. Every engagement starts from your diagnostic, not a generic template.
How it works
Straight to the point, no slide decks. A clear deliverable at every step.
Free diagnostic
30 minutes: you show the architecture and Cost Explorer, I point out the biggest risks and the fastest savings to capture.
Proposal
A fixed scope with clear priorities — what puts out the fire first, what's a mid-term investment. Fixed price or per sprint.
Implementation
I work directly in your repo, with PRs your team can review. No untracked root access.
Evolution
Ongoing follow-up and new optimization cycles as the business grows.
Case studies
Published, anonymized work — real methodology and numbers, not a slide-deck case study.
$300k/year cut from an AWS bill without changing the architecture
Lambda rightsizing (2GB → 768MB, −61%) and RDS io2 → gp3 migration, driven by metric analysis in CloudWatch Logs Insights. ~$25k/month saved.

Analytics moved off production: Hub-and-Spoke topology, Apache Iceberg v2, Glue/PySpark, Athena and Lake Formation governance. A 300s query dropped to 28s.

What changes when it's real senior engineering.
Senior end to end
Whoever designs the architecture is the one who ships the PR. No account manager, no hand-off to a junior.
Built for mid-market pain
Not an automation package for early-stage startups. It's for companies that already have traffic, already have data, and already feel the cost of old technical decisions.
Proof, not promises
Every number here is documented, with open methodology, in a published article. Check it yourself.
Frequently asked questions
What size company is Cerradum for?
Mid-market companies already running production in the cloud that feel scale, cost or reliability pain — not startups validating an MVP.
How much does it cost?
It depends on scope. After the free diagnostic you get a fixed price — flat or per sprint, never a generic "package".
Does this replace my engineering team?
No. I work with your team, not instead of it — the goal is to fix the problem and leave knowledge behind, not create dependency.
Do you only work with AWS?
Most of the depth is in AWS, but the principles (IaC with Terraform, Kubernetes, data platforms) apply to hybrid and multi-cloud environments.
How does a project start?
With the free 30-minute diagnostic. From there you get a clear, no-commitment proposal.
Let's find the biggest risk (and the biggest savings)?
30 minutes, no commitment. You'll leave with an honest diagnostic: where the biggest risk is, and how much you could save without rewriting anything.
