Bonifácio
Specialist cloud and data platform engineer
I design the platform, automate it with Terraform and make it observable. Eleven years on GCP, AWS and Azure, across global retail, fintech, multi-cloud consulting and SaaS. Today I lead AI agents for IT support.
This is the kind of system I run today:
Measured results
- US$140k

- Second Nature
- 4M+
- events a month at 99.9% SLA
- Second Nature
- 40%
- faster incident resolution
- Burger King

What I solve
Data platforms on GCP
CDC ingestion from another cloud, bronze, silver and gold layers in BigQuery, orchestration in Composer, and governance that passes SOC2 and PCI DSS audits.
4M+ events a month from 1,500+ clients, at 99.9% SLA.
Cloud with Kubernetes and Terraform
Infrastructure as code as the only change path, hardened clusters, and CI/CD that deploys without downtime on AWS, GCP and Azure.
30% fewer PCI audit gaps, and deploys cut from days to hours.
AI agents for IT support
TypeScript SDKs that serve users over Teams and WhatsApp, classify with an LLM over the full catalog, and operate the ticketing system.
Today, as tech lead, in a lab and as proofs of concept.
Cases
Each case covers the problem, what I did, the result and the system diagram.

AI agent SDKs for IT support
IT consultancy, tech lead, present
As tech lead at an IT consultancy, I build TypeScript SDKs that handle L1 to L3 support over Teams and WhatsApp, integrated with the ticketing system, in a lab and as proofs of concept.

An AI agent that audits the data platform
Second Nature, proof of concept
Proof of concept of a read-only agent that reviews platform telemetry and, unprompted, found a leaked key and a pipeline failing about 40% of the time with no alert.

Moving a multi-tenant SaaS platform to another cloud
Consulting client
I migrated all three environments of a schema-per-tenant SaaS off hand-built VMs, and found the driver incompatibility that broke every new environment.

From low-code flows to an AI-orchestrated lead pipeline
Consulting projects
Lead qualification pipelines (WhatsApp capture, AI qualification, CRM sync) built in n8n, Jitterbit and SkyOne, and now the same problem with an agent that decides each step.

Lead qualification and follow-up for a solar energy company
Consulting client
Audit and stabilization of a B2C solar energy client's lead automation: the follow-up queue dropped from about 1,300 records to fewer than 40.
