hi, i'm Alexandru.

Deeper than the framework. React, Laravel, C++ runtimes, embedded hardware, reverse-engineered protocols - six years building systems that hold.

C++ · Laravel · React · Bucharest · remote

Self-taught since 10.
     Full-stack by practice, low-level by instinct.

Started at 10, self-taught all the way. C++, Java, then full-stack web, hardware, and protocols - 6+ years of real production work.

I connect the full stack: React frontends, Laravel APIs, C++ runtimes, embedded devices, and reverse-engineered protocols.

Fast and independent. I don't just use frameworks - I understand what runs underneath them.

Integration, implementation, systems that hold.

Systems I've built.

A mix of production work, C++ systems, embedded hardware, and reverse-engineering projects.
