Habitable software for the agentic era

I'm a software crafter who helps teams of humans and agents build high-quality, simple software that lasts

About me

I've been working in software development for over 25 years. I've written code, led teams, trained developers and built more than a hundred products from scratch. I'm the co-founder and CTO of 404 Crafters.

What I care about most is habitable software: software people can understand and change with confidence. Over the years I've learned that this is what lets teams move fast and keep that pace.

I work with Extreme Programming practices, adapted to each business, with agents as part of the team.

My services

CTO on Demand

Strategic technical leadership for startups or teams without a CTO.

  • •Support founders and technical teams at key moments: product definition, roadmap, architecture design, technology choices, team formation and ways of working.
  • •Help validate ideas, prioritize features, launch MVPs with solid foundations and scale without over-engineering.
  • •Bring AI into the product and the way you work, so it amplifies the good and not the bad.
  • •Always hands-on, focused on speed, simplicity, and long-term sustainability.

Product development & automation

Robust, clear software designed to grow without friction.

  • •Design and build end-to-end products: web, mobile, desktop, backend, APIs and architecture.
  • •Bring AI into your products where it adds value: agents integrated with your system, RAG over your own data and MCP, with guardrails, evals and observability.
  • •Automate your business processes with agents and integrations: understand how your team works, find what's worth automating and take it to production.
  • •Work with people and agents in parallel, without degrading quality or piling up cognitive debt.
  • •Deliver in vertical slices, continuously from the start, prioritizing business value, simplicity and sustainable technical decisions.

Technical consulting

Diagnostics and guidance to strengthen your technical foundation.

  • •Assess systems and processes with a holistic view that connects business, team, architecture and code.
  • •I review, simplify and modernize solutions that are creating friction or accumulating technical debt.
  • •Help you take advantage of AI's speed and run agents in parallel without degrading code, architecture or quality, and without piling up cognitive debt (code the team no longer understands). With harnesses, skills and orchestrators.
  • •Guide the team in adopting technical excellence practices like TDD, refactoring, evolutionary design, clean code, CI/CD, and pair/mob programming.
  • •Improve quality and lower costs and risks, so your team delivers business value early, predictably and sustainably over time.

Mentoring and training

Hands-on training to build skills and transform how teams work.

  • •I design and facilitate courses, workshops and training programs tailored to each team's level and context.
  • •Teach the fundamentals: TDD, object-oriented design, simplicity, software design principles, clean architecture, clean code, extreme programming and agile philosophy. They're the foundation to lead agents without losing control of the product or its quality.
  • •Through practical sessions, pair/mob programming and structured guidance, I help teams not only improve their skills but radically rethink how they understand and build software.
  • •Ideal for accelerating developers, leveling up teams, and strengthening technical culture across the organization.
