Software architect and engineering lead with 23 years building and running systems where failure is expensive. I work across the full technical range — Java and Spring Boot, Angular and Node.js, microservices, cloud on AWS and GCP, identity and access management, event streaming, and the container and CI/CD tooling that keeps delivery predictable.
I adapt quickly to new stacks, new teams and new business domains, and have delivered in financial services and crypto-asset trading, sports, energy, public security, tax and the justice sector. I have built development teams from hiring through to structured handover, and worked equally as hands-on engineer, architect and technical leader.
What carries across all of it is the same thing: turning business constraints into architecture a team can actually execute.

Consultant — AI, cloud and product
Technology consultant
Consulting across sectors
Advising companies on bringing AI into how they build software — agent-assisted engineering with the specifications, review gates and delivery cadence that make it dependable rather than experimental.
Cloud infrastructure on AWS and GCP: environments designed for the load they will actually carry, automated end to end, with the trade-offs written down.
IT product development from the first specification to a shipped product — architecture, team and operating cadence. My own products, DOP and Spartacus, come from this period.

An AI-first cockpit where a developer and Claude run a demand end to end
The problem
Running a software demand — environment, branch, development, pull request, delivery — is a chain of hand-offs between the developer and an AI agent that lose state at every step.
The approach
A Go core owns the domain, the state and a transactional event log; a Python BFF exposes REST and SSE to a React cockpit and gRPC to the CLI; the developer follows and steers from above while the agent operates the tooling underneath. Multi-tenant from the first migration, a second factor built in before any organisation existed, and every action recorded as an event with its context and a dead-letter queue for the ones no consumer could handle.
Where it stands
A QA environment on GCP: the core and the BFF on Cloud Run behind api.qa.dop-t.com, sign-in through Firebase, e-mail through SendGrid, a data VM on the free tier — all in Terraform, designed to carry no fixed monthly cost, with a smoke test that proves the chain from a real sign-in to a row in the database. The cockpit signs people up, enrols a second factor and handles invites. Twenty-three architecture decision records, a proto-first contract, a local k3d environment that brings the whole platform up in one command, and a public site at dop-t.com. Under construction, with a QA environment live on GCP; the operational CLI is in daily use (v0.7.1).
Web back office and mobile app for a martial-arts social project in Brasnorte, Mato Grosso
The problem
A social project teaching jiu-jitsu, capoeira and Muay Thai to children needed attendance, monthly food-donation tracking and a channel to families — without a secretary becoming a queue operator and without a hosting bill.
The approach
One QR code per class instead of one per student, so the teacher never queues anyone. Guardians act on behalf of their children with dual authorship on every record. A FastAPI back end on Cloud Run, Firestore, and Firebase Auth with Google sign-in for adults.
Where it stands
Six repositories — app, back end, back office, shared UI components, infrastructure and a prototype — shipped to the families of Brasnorte at zero operating cost. In production, running on GCP's free tier.
