Hi, I'm Angel

Turning ideas into solid, adaptable software

Senior full-stack engineer and consultant with 15+ years of experience.

From MVPs to long-term systems. Infrastructure to frontend.

Specialised in Ruby on Rails backends.

What I Do

Design & Build

  • Build and evolve MVPs and production systems
  • Focus on clarity, maintainability, and adaptability over time

Backend Expertise

  • Ruby on Rails architecture and implementation
  • APIs, background jobs, integrations, data modelling

Full-Stack & Infrastructure

  • From deployment and operations to frontend integration
  • Comfortable working across the entire stack when needed

How I Work

Execution & Ownership

Autonomous, accountable execution with clear priorities and consistent follow-through from decision to delivery.

Adaptation & Problem Solving

Comfortable with uncertainty and rapid change, making pragmatic choices that balance speed with long-term soundness.

Communication

Clear, direct communication with technical and non-technical stakeholders in English, Spanish, and Italian.

Trust & Professionalism

Client work is treated with discretion by default, building trust through reliability, consistency, and a calm professional approach.

Work & References

Public Work

I actively contribute to the open-source community, sharing projects and improvements that support developers and libraries used worldwide.

Private Work

Most of my work is private, developed under NDA or trusted collaboration.

  • Projects range from short consulting engagements to long-term product builds
  • I often start with MVPs for startups, then adapt systems as the product grows
  • Performance optimization and technical consulting
  • Confidentiality and discretion are always maintained

Who I Work With

Engagements range from short, focused consulting to longer-term collaborations that often start small and evolve over time.

Startups & Early-Stage Teams

  • Exploring ideas, validating concepts, and building MVPs
  • Rapid iteration and frequent course correction

Technical Teams

  • Senior execution, architectural guidance, or focused problem-solving
  • Short-term or ongoing collaboration

Founders & Decision-Makers

  • Technical direction, evaluation, and consulting
  • Support in defining the right path, not just executing a fixed plan

About

Over 15 years building software across a wide range of systems and contexts. Much of my work involves early-stage products that need to move quickly, adapt, and still remain maintainable.

I value calm execution, clear communication, and systems designed to evolve as requirements change.
