About
I am a developer focused on building reliable and efficient system foundations. I enjoy designing the logic behind applications—how systems operate reliably, scale effectively, and remain maintainable over time.
My interest in systems began during my university years, when I had the opportunity to work on a project aimed at supporting people with disabilities by enabling them to showcase and sell their creative work. This experience shaped my understanding of the importance of building systems that not only function well, but also create meaningful impact for their users.
Currently, I am deepening my expertise in backend development and infrastructure. I focus on exploring scalable services, optimizing databases, and applying infrastructure automation to ensure systems are prepared to support sustainable product growth.
In my free time, I enjoy exploring new technologies, working on side projects, and continuously refining my understanding of how systems can be built to be more robust and efficient.
