About

My family introduced me to the world of technology at a young age, and that early interest eventually grew into a passion for building software and solving real-world problems.

I started my career working in technical support and systems operations, where I gained hands-on experience troubleshooting hardware, software, and network systems in fast-paced environments. Over time, I became more interested in creating the tools behind the systems I worked with every day, which led me deeper into software development and full-stack engineering.

Today, I enjoy building realtime applications, backend systems, and modern web experiences that turn complex information into simple, useful products. I'm always looking to keep learning, improve my skills, and continue the legacy that first inspired me to get into tech.
