About me

About me

Software developer who likes turning hard problems into efficient, precise solutions.

Jose Manuel Martínez

I'm Jose Manuel Martínez, a software developer from Spain. I've been into computers since I was a kid — I wrote my first HTML at 13 — and that early spark grew into a craft I take seriously. Most of what I build runs in production every day: industrial terminals, ERPs, real-time dashboards and mobile apps.

What I enjoy most is taking a problem, turning it over from every angle, and finding the best possible solution for that specific case — then pushing it to be as optimal and precise as I can. I work across the stack, most at home on the backend, and I care more about whether something actually works and holds up than about buzzwords.

Outside of code I'm a biker and a motorsport enthusiast, and I've done sport since I was eight — swimming, taekwondo, boxing, CrossFit — and lately I'm at the gym training high-intensity strength. I also build my own personal projects and ventures, and I'm open to freelance work.

How I work

Philosophy

I like breaking down tangled problems and shipping solutions that are efficient and easy to maintain. I work across the full stack — most at home on the backend — pick up new tools quickly, and I'm comfortable both leading a project and working as part of a team.

I've also worked with the Lean methodology to improve processes and productivity, applying its principles to cut waste and keep workflows improving.
