Message

I'm a technical support professional with over five years of experience helping customers resolve complex software issues across SaaS platforms and enterprise applications.

My expertise includes L1/L2 technical support, SQL-based investigations, REST API troubleshooting, log analysis, and browser developer tools. I've worked closely with engineering and product teams to investigate escalations, identify root causes, and implement lasting solutions. I also enjoy improving support processes, creating technical documentation, and making complicated technical concepts easier to understand.

With a Master's degree in Software Engineering, I bring both a customer-focused mindset and a strong technical foundation to problem-solving. Beyond technical support, I have experience in 3D art and game development workflows, which has strengthened my attention to detail, creativity, and ability to learn complex software.

I'm particularly interested in remote opportunities with SaaS and technology companies where I can tackle challenging technical problems, collaborate with talented teams, and continue growing professionally.
