Vision
The path I’m building ahead
I believe the future of software lies in transparency, automation, and resilience.
As a developer at the intersection of system-level programming and full-stack development, I combine low-level performance with high-level usability. I primarily work with Rust and Node.js, selecting the best tool for each scenario.
I'm committed to open source as a core philosophy. Whenever possible, I release my work publicly — because great software grows through collaboration, visibility, and shared ownership.
I see cloud-native development as the backbone of modern infrastructure. From CaaS, Docker, and Kubernetes to CI/CD pipelines, I design systems that are scalable, automated, and built for continuous delivery.
