👋 Hey there! I'm David. I am a Senior Software Engineer at Chainguard 🐙. I have a strong passion for distributed systems, microservices, secure data processing systems, Go, Python, and speciality single-origin coffees.
🖥️ I’m currently a Senior Software Engineer at Chainguard. Previously, I was a senior software engineer at Bestow, and before that, I was a software engineer at Atlassian on the Jira Align and Bitbucket Cloud teams.
📰 Note: I previously went by DataDavd/datadavd online (a relic from my old data engineering days), but now use codeaucafe as my GitHub username. Also, if you see github/CSddansby come up in your searches of me that is my old Credit Sesame organization GitHub account that Credit Sesame never closed after I left. So, please ignore CSddansby as codeaucafe is now my primary GitHub username.
💻 Beyond my day job, I'm committed to continuous growth: contributing to open source (mainly Dolt lately, which is a MySQL-compatible SQL database with Git-like version control, written in Go), reading about and exploring software architecture, distributed systems, programming languages, and software design patterns, and advancing my Go proficiency.
📚 Outside of software engineering and tech, I enjoy learning French, snowboarding and hiking with my brother and friends, and traveling with my wife.
