01 — About

A hybrid engineer, on purpose.

Full-stack web developer with over a decade of experience and 200+ delivered projects, now deliberately expanding into AI and embedded systems. My core is the web stack — PHP, Laravel, WordPress, React and JavaScript — backed by solid experience leading teams as Scrum Master and Technical Lead under agile methodologies. I am building on that foundation with the integration of AI agents and LLMs into real products, plus hands-on ESP32 firmware (C/C++) and IoT devices.

The result is a rare hybrid profile: equally comfortable shipping a Laravel application, building a professional website, wiring an LLM into the loop, and flashing firmware to a microcontroller.

Beyond the keyboard

The habits and side quests that keep the engineering sharp.

Tinkering with hardware

Weekends go into breadboards, motor drivers and the occasional magic smoke.

3D design & printing

Designing and printing my own PETG parts — chassis, mounts, brackets.

Continuous learning

CS50x, C/C++ and robotics — currently heading toward ROS 2 and STM32.

Building in public

Documenting personal builds and sharing what breaks along the way.
02 — Tech stack

Tools I reach for.

From production web apps to LLMs in the loop to firmware on bare metal — organized by where they live in the stack.
