What I'm looking for

I seek a backend role focused on API and cloud infrastructure (Docker, AWS/DigitalOcean), with opportunities in DevOps and system hardening. I prefer collaborative SME teams that prioritize reliability, scalability, and security while offering growth and hands-on responsibility.

I am a backend-focused software developer with hands-on experience designing and implementing REST APIs using ASP.NET Core, Java, and Spring Boot, backed by SQL Server and MySQL. I have performed server administration on DigitalOcean and AWS EC2, managed Docker and Docker Compose environments, and supported frontend work with React while collaborating on GitLab CI/CD pipelines.

I have worked across SMEs to maintain, optimize, and secure systems, with roles spanning system analysis, desktop and web application development, virtualization (Proxmox, VMware), and scripting in Python and Bash. I bring a pragmatic, security-minded approach to backend development and cloud infrastructure and am passionate about building reliable systems for growing teams.
