About
Professional summary aligned with engineering and operations work
I am a software engineer with hands-on experience across product development and day-to-day operations. My work spans frontend and backend delivery, API design, database integration, Linux-based deployments, reverse proxy setup, virtualization, and practical server and network administration. I am targeting roles where software development, platform ownership, and infrastructure thinking need to work together.
My experience sits between product delivery and infrastructure ownership. I have worked on frontend interfaces, backend APIs, database-backed systems, Linux servers, containerized deployments, reverse proxies, virtualization setups, and remote access networking. That combination makes me most effective in roles where shipping features also requires operational awareness, troubleshooting discipline, and a solid understanding of the environment those applications run in.
