Trading Fish The website of Hector Castro


I am an engineering lead active in software development, web architecture, and infrastructure automation. I enjoy helping teams realize the value of their work by improving the reliability and speed of software delivery. I have a strong background in DevOps practices and have been actively developing my software leadership skills over the last six years.

My focus is on remote opportunities to create positive social impact through technology. My ideal next role is as a tech lead or engineering manager supporting small to medium-sized teams. If you are interested in chatting, please hit me up on Twitter, Mastodon, or LinkedIn.
