Wandered. Did some travel but mostly tried out business ideas that ended up not working:https://jacek.migdal.pl/2024/01/07/the-year-of-exploration.htmlHowever, I enjoyed the process, learned a lot, and discovered that database gateway should be my next thing.

From early employee pre-revenue to $2Bln+ Initial Public Offering (NYSE:SUMO).Major accomplishments:1. Created the Sumo Logic Warsaw office (~86 FTE). Personally sourced and hired ~30 employees, mostly engineers (ex-Facebook, Microsoft, Teradata, Hedge Fund employees). Made them productive quickly through training. Later professionalize structure, which included hiring site lead.2. Improved gross margin by ~50% reduction of AWS costs in a year. Lead the engineering execution of multiple projects: some reduced waste and chaos, other increased efficiency by better algorithms (e.g. stream processing) or more efficient data structure (40% smaller full-text indices). The improvements continued over the years, which allowed Sumo to compete on economics while maintaining high gross margins.3. Creatively recruited the team and led the Tracing team's execution. It launched a new product with the first commercial win in less than a year. In two years recognised Sumo Logic as a Challenger in the 2022 Gartner® Magic Quadrant™ for APM and Observability.4. Implemented and maintained encryption infrastructure for security and compliance (including PCI)5. Removed more lines of Scala code than added. Simplified and reused many components.Positions:- Sep 2021 - Dec 2022: Senior Director of Engineering- Jun 2019 - Aug 2021: Director of Engineering- Mar 2018 - May 2019: Senior Engineering manager, executive of Sumo Logic Poland- Sep 2017 - Feb 2018: Engineering manager, executive of Sumo Logic Poland- Nov 2016 - Aug 2017: Engineering manager- Apr 2015 - Oct 2016: Senior software engineer; Warsaw, Poland- Oct 2014 - Mar 2015: Senior software engineer- Oct 2013 - Sep 2014: Backend software engineer; Redwood City, California- Sep 2012 - Sep 2013: Backend software engineer; Warsaw, Poland (remote)- June 2012 - Sep 2012: Software Intern; Mountain View, California- April 2012 - June 2012: Part-time contractor; Warsaw, Poland (remote)
