What I'm looking for

I am looking for development-focused roles where I can write quality, scalable code, grow technically, and contribute to stable production systems.

I am a software developer with hands-on experience building and maintaining C# and JavaScript solutions for MES (Apriso) in industrial production environments, focused on bug fixes, continuous improvements, and system stability. I have supported feature integration, created and maintained SQL queries for operational data analysis, and provided technical support for critical systems.

With a background in Java and corporate support roles, I bring strong programming logic, systems analysis, debugging skills, and experience in incident resolution and functional testing. I am currently pursuing a Bachelor of Computer Science (expected 2026) and seek development-focused opportunities to contribute quality, scalable code and grow technically.
