About Me

A brief overview of who I am and what I bring to projects.

I’m Ariel J. Tshibangu, a Full-Stack Developer and Security Expert with a focus on building reliable, secure and maintainable applications. I combine strong engineering practices (TDD, CI/CD) with security-first design (OWASP principles) to deliver scalable products that users trust.

My work covers the full lifecycle: product thinking, architecture design, implementation, testing, deployment and monitoring. I enjoy solving complex problems — from optimizing database queries to hardening authentication flows and automating deployment pipelines.

Tools & habits I use daily: Laravel, React, Flutter, PostgreSQL, Docker, GitHub Actions, and regular security audits. I also value mentorship, clean code, and readable documentation.
