// dev from the real world

I build beautiful interfaces and stable systems.
Yes, you can have both.

Clean code, delivery without corporate theater and zero excuse of "the environment broke". If the problem is real, I solve it.

If your project needs someone who…

…understands business, writes decent code and doesn't turn a simple task into a corporate saga, then we have real chances of getting along.

Fix systems nobody wants to touch
Legacy code recognizes me from a distance. Usually by the noise I make.
Build systems without artistic overcomplification
Fast, functional and built to operate. No useless modules just to inflate the budget.
Make websites that look expensive
Strong visuals, clean experience and that detail the Canva nephew doesn't deliver.
Integrate temperamental APIs
No documentation, weird responses and creative authentication? Familiar territory.
Think results, not just pretty screens
Pretty layout impresses. Conversion and consistent use pays the bills.
Apps that work in the real world
Fast, intuitive and stable. Even on the client's tired Android they swear is brand new.
// real cases, real results

left the theory.

Journey
without the fluff.

The kind where each phase left real learning, technical calluses and actual deliveries.

2021
Started building WordPress sites
First clients, first urgent demands and the beginning of the relationship between tight deadlines and coffee.
2022
Went all-in on programming
Self-taught, intensive courses, certifications and the discovery that Google and YouTube also teach a lot (GPT was still getting famous).
2023
Tried college. Preferred my own pace.
Quickly figured out that learning on my own produced more than waiting for the next slide.
2024
First official opportunity as a dev
Joined Fretador. React Native, Node.js and Next.js. Real production, real problems and zero tutorial mode.
2025 - 2026
Next level at ProSales
German software house. Development on systems tied to the crypto market, KYC, integrations and operations where mistakes are costly.
// technologies

Technologies I use
without crying.

Back-end & Databases
PHP Node.js MySQL MongoDB REST API Legacy APIs nobody wanted to touch
Front-end & Mobile

Tools & Others

// work philosophy
✓ Documentation is not bureaucracy. It's respect for whoever maintains it later (but if there isn't any, we'll figure it out).
✓ If you can't explain it to a non-dev, it's too complicated.
✓ Good code is what works in production, not in CodePen.
✗ I'll never refuse a hard problem just because it's "out of scope".
// next steps

If you need a dev
that delivers without
corporate theater, reach out.

No endless meetings, no inflated promises and no overcomplicating what could already be working. Tell me the scenario and I'll tell you the path forward.

Chat on WhatsApp Prefer email? Strangely respectable.

Average response time: enough to look like I actually work.
