Software Engineering, development, architecture, consulting, management

I can help build a team and deliver production following best practices with multiple deployments to production per day. I lead by example, demonstrating the way of fast-paced iteration with a focus on defensive programming and chaos engineering. My approach is simple: ‘don’t try to make it work, just make sure it doesn’t failed.’ This results in high availability (in a serverless environment) and reduces outages.
