👋 Hey there friend!!! I'm David. I am a Senior Software Engineer at Bestow. I have a strong passion for distributed systems, microservices, secure data processing systems, Go, Python, and rare single-origin coffees. When time allows you can find me tinkering with one of my split mechanical keyboards.
💪 I’m currently a Senior Software Engineer at Bestow (check us out). Previously, 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 data engineering days), but now use codeaucafe as my GitHub username.
💻 Outside of work I'm constantly learning and improving my skills. I like doing LeetCode, improving my knowledge of various software system designs, reading software-related books, and improving my Go knowledge.
📚 Outside of software engineering and tech, I'm learning French, snowboard with my brother and friends, and love traveling with my wife.
