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

Started coding at 10, self-taught. 6+ years shipping production software.

Built React frontends, Laravel APIs, embedded systems and C++ infrastructure.

Integration, implementation, systems that hold.

Systems I've built.

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

OmniRift

Cross-platform C++ game engine.

Teams building cross-platform games and simulations need an engine that isn't locked to one vendor's toolchain or a single target platform.

A single C++ engine - OpenGL renderer, 2D/3D pipeline, editor tooling - that targets Windows, Linux and game consoles from one codebase.

Already running a second project on top of it (Flipvert) - my BSc thesis, validated outside its own thesis context.

Smart Health Monitoring System

Patient vitals + environmental hazard alerts.

Patients and caregivers often can't detect combined health and environmental risks - vitals and hazards like smoke, gas or heat - in real time.

A wearable that reads vitals and detects smoke, gas and heat in real time, later rewritten in C++ for reliability.

Won 1st prize at MobilPro 2018, Polytechnic University of Bucharest - built at age 14.

NekoSSO

Centralized SSO with OAuth2 + JWT.

Growing product suites end up rebuilding login and permissions for every new application, duplicating logic and risk.

A Laravel service handling OAuth2 and JWT login, role-based access, and sessions - exposed as one API every app can plug into.

Used as the shared identity layer, so new applications plug into existing auth instead of rebuilding it.

Yahoo! Messenger, revived.

A discontinued messaging protocol left its client and user base with no working server and no public documentation.

Reverse-engineered YMSG and rebuilt the full server - messaging, friend lists, notices and SIP voice - in Node.js, then C++.

Fully working reimplementation of a proprietary protocol with zero official reference material.
