the beginning

Linux at nine. Web ever since.

I installed Fedora Core 3 all by myself at the age of nine. That was the gateway, and I've used Linux every single day since. It wasn't a tool I picked up along the way; it's the foundation everything else was built on. Today I run Arch Linux and feel at home deep in the system, from kernel configuration to network hardening.

Not long after that first install, I started learning HTML. Then CSS, then PHP, and the story kept going. By late primary school I was already curious about web security, learning common attack vectors and bug types in web applications. I even built my own webpage in 2005, at the age of twelve: it still exists in the archive.

what drives me

Work that matters, craft for its own sake.

I believe in open source and in doing things driven by love for the craft, not just a paycheck. I have a deep need to use my skills for meaningful impact: to build things that genuinely help people and make a positive difference in the world. Code for code's sake isn't enough; I want the work I do to matter.

I'm very ambitious. These things are my passion and I pursue them regardless of job, payroll, or mood. I want to get involved in something real: code with people I can learn from, and together create something significantly great.

craft

Elixir first, Rails a close second.

Elixir is my favourite language. I love how it mixes the simplicity of Ruby with the beauty of the functional paradigm, and how it makes building concurrent, fault-tolerant systems feel natural. Ruby is a close second; it shaped my professional career and I still feel at home in the Rails ecosystem.

now

AI specialization, from the road.

In June 2025, after a successful 3.5+ year tenure, I voluntarily left my role to fully commit to exploring, implementing, and researching AI: LLM integration, generative media pipelines, vector search strategies, RAG, and neural network foundations. Hands-on, mostly in Python.

Since November 2025 I've been travelling. Six months through Asia (Thailand, Malaysia, Indonesia, Bali, Vietnam, the Philippines, Japan) reshaped my perspective on life, people, and what matters. Right now I'm in Greece, but that changes fast. I'm still travelling, and open to remote work or relocation.

about me

Social, confident, and always learning.

I'm a very social and confident person. I love to sing, and I played some guitar a while back. And if there's a technology I don't know yet, I'll learn it before I start working with you. This is IT after all. It's all about learning and the power of the mind.
