About me

Daniel Pecos Martínez

Senior Software Engineer, Architect, and Consultant currently based in the Amsterdam area, Netherlands. I am a passionate developer, blogger, and open-source enthusiast with over 20 years of experience in the industry.

Professional Profile

Currently, I serve as a Staff Software Engineer at Decathlon Digital and also act as a Software Architect & Consultant at dplabs.tech. My expertise spans across several technology stacks, with a strong focus on building robust, scalable, and maintainable systems.

I am a strong advocate for TDD (Test-Driven Development) and Agile practices. I enjoy sharing my knowledge and frequently speak at technical conferences like FOSDEM, as well as participating in local user groups (JavaScript, Golang, Frontenders, Makers).

Technologies & Expertise

I consider myself a polyglot developer with a broad range of expertise:

  • Languages: Go (Golang), Java/JVM (SCJP5 Certified), Node.js/JavaScript, Rust, and Python.
  • Backend & Systems: Designing distributed systems, microservices, and modern API architectures.
  • Infrastructure: Homelab enthusiast, self-hosting services using Docker and Kubernetes, and monitoring with Grafana and Prometheus.
  • Security: Expert in OpenPGP/GnuPG and web security.
  • Open Source: Author of several projects like mastodon-comments (a web component for embedding Mastodon conversations), ays (a CLI tool in Rust), and sshkeys (an SSH key manager).

Hobbies & Personal Interests

Beyond coding, I have a wide variety of technical and creative interests that keep me busy:

  • HAM Radio: I am a licensed amateur radio operator with callsigns PA1DPM (Netherlands) and EA5JBR (Spain). You can often find me experimenting with mesh networks or participating in radio events.
  • Tabletop RPGs: I am a fan of Dungeons & Dragons and other TTRPGs. I recently started exploring the Daggerheart system and enjoy introducing new players to the hobby.
  • Homelab & Electronics: I maintain a personal homelab for experimentation and learning, and I enjoy tinkering with electronics and Raspberry Pi projects.
  • Blogging: I write about technology, Linux, radio, and my various projects here on my blog, GeekWare.
