What I'm looking for

I'm looking to modernize production platforms through backend architecture, containerization, Kubernetes, and highly available infrastructure, while improving delivery speed, reliability, and operational efficiency.

At Bitcat Services, I design and operate production server, storage, Kubernetes, and Proxmox infrastructure while building internal business platforms. I reduced deployment-related errors and response times by around 80% through GitHub Actions and Docker.

Previously, as Backend Lead Developer at AIA Partners, I designed a Node.js and Express fintech backend that cut API response times by about 30% and application errors by about 40%. I also implemented MongoDB replica sets, secure file storage, automated jobs, and mentored the development team.

I'm focused on modernizing legacy environments with Docker, Kubernetes, Talos Linux, and highly available Proxmox infrastructure backed by LINSTOR/DRBD replication.
