About

I'm Pepe Márquez Romero, a software engineer with 3+ years of experience building reliable systems at the intersection of embedded systems, distributed architecture, and fintech. Currently based in Estonia, I'm passionate about creating robust, scalable solutions that solve real-world problems.

What I Do

I specialize in building systems where reliability matters. At Yolo Group, I worked on payment systems that required zero-tolerance for failure, focusing on reliability engineering in a fintech environment. My technical interests span embedded systems, distributed systems, and backend architecture — I love working across the full stack and diving deep into complex problems.

As a polyglot developer, I work fluently in Elixir, Rust, Zig or any other language choosing the right tool for each challenge. I'm particularly excited about embedded systems and IoT, where hardware meets software.

Open Source & Community

I believe in learning and building in public. I actively contribute to open-source projects, including:

• Nerves Hub - Platform for firmware updates in embedded Elixir systems
• Name Badge - Embedded system in Elixir
• sqlx, frankenstein, cryptopunk - Various contributions including bug fixes, features, and documentation

I've also created tools like lazy_doc and weather_bot, and maintain fang as a core contributor.

Beyond code, I share knowledge through talks and teaching. I gave A Rust Introduction to help others get started with systems programming (talk repository).

Background

Education: Universidad Politécnica de Madrid, School of Computer Science

Experience Timeline:

• Elixir (2021 - present): Production systems, embedded programming with Nerves
• Rust (2020 - present): Systems programming, open-source contributions
• Python (2020 - present): Scripting, automation, and backend services

I bridge the gap between academic computer science and industry practice, bringing both theoretical foundations and pragmatic problem-solving to every project.

Looking Forward

I'm actively seeking opportunities where I can work on embedded systems, distributed systems, or challenging backend problems. I thrive in environments that value code quality, open-source contribution, and continuous learning.

Let's build something reliable together.
