Filip Niculae

Software Developer

Computer Science student focused on backend engineering and building practical software solutions. Hands-on experience with Java, C++, JavaScript, Docker, and REST APIs through professional internship work and independent technical projects.

Business-First Logic

I build solutions tailored to actual workflows—whether it's streamlining data for accounting cabinets or handling automated webhooks to prevent negative inventory.

Reliable Architecture

Focused on system stability through atomic database transactions, secure client-server validation, and robust hardware fail-safes.

Full-Stack Vision

From low-level C++ hardware integration to deploying decoupled Next.js/NestJS micro-repositories, I understand how the pieces connect.
