I enjoy finding what breaks, understanding why, and making the next investigation easier.

My work lives where software quality, monitoring, Linux operations, and network/ISP infrastructure overlap. I test web and Android applications, monitor servers and network devices, investigate incidents, and look for clearer ways to see what is really happening.

Software development is not my primary role. I build apps because it is one of my favorite ways to practice QA, explore ideas, learn new systems, and turn personal R&D questions into something testable.

These are learning, practice, personal-idea, and R&D projects—not a claim that software development is my primary professional role. I build to explore, and I test what I build.
