Description

Senior software engineer focused on backend systems, automation, and production troubleshooting. I help teams fix, stabilize, and improve existing systems without unnecessary rewrites.

My experience covers backend services, APIs, data pipelines, scripting and automation, cloud workflows, and integrations with third-party systems. I prioritize pragmatic solutions that are safe to ship and easy for teams to maintain.

If you need a senior engineer to unblock work, reduce operational pain, or clean up technical debt efficiently, I can step in and help.
