Systems that hold.

I build software that behaves at 3 a.m. exactly the way it did in the demo — now with AI in the loop and engineers on the hook.

About

I work where engineering, architecture and leadership overlap.

I lead the development of scalable and reliable systems — helping engineering teams break down complex problems while keeping a hard focus on business impact, operational efficiency and long-term maintainability.

Five years across e-government, e-commerce, payments and insurance. Most of what I ship is the unglamorous kind: reconciliation that has to balance, SLAs that can't slip, pipelines nobody should have to think about.

AI workflow

Agents write the code. Engineering decides what ships.

I use AI the way I use any production system: grounded in real context, checked by tests and evals, signed off by a human.

  1. 01

    Grounded before it writes a line

    The agent starts from the ticket, the decision records, the schema and the logs — not a blank prompt. Context is assembled, not improvised.

  2. 02

    A plan you can review in a minute

    Work is split into small changes by layer, so the diff is predictable before anything is generated.

  3. 03

    Tests and evals decide, not vibes

    Every iteration runs types, unit tests and an eval suite built from real cases. The pass rate has to climb before it earns a human's time.

  4. 04

    Human sign-off, then a careful rollout

    A reviewer approves, CI deploys a canary and the same dashboards watch it. If a number moves, it rolls back on its own.

Responsiveness

One product, every screen.

You are in the session too: click the screen or change the theme, and the code follows.

01

Architecture that fits the problem

Not a monolith out of habit, not microservices out of fashion. The shape follows the domain and the team.

02

Reliability is a feature

SLAs, idempotency, replayable events and dashboards that answer the question before someone asks it.

03

Leave it documented

Decision records, runbooks and tests, so the team keeps moving after I step out of the room.

Automation

Manual work, rebuilt as workflows.

Most teams lose hours copying data between WhatsApp, spreadsheets, email and the CRM. I map the process, then rebuild it in n8n: an LLM where judgement is needed, plain rules where it isn't. Every run is logged, retried and easy to change.

Reliability

Built to keep serving when a region goes dark.

Health checks, weighted routing and slow start are design decisions, not afterthoughts. This is the failover drill every critical system I lead is built to pass.

Stack

What I reach for, and why.

The orbit rests while you aim. Filter by category or pick a logo to see where it fits.
