About

Happily executes at many levels from an engineer through the coding manager to the site lead. As a site lead: inspires, provides a focus, debugs, and executes. Attracts talent and build the organization machinery. Keeps learning to stay technical relevant. As a director: incubates the new teams mixing internal and external talent. Launches and iterates quickly on a new product. Accelerate velocity, keep morale high, and balance conflicting priorities. As a coding manager: loves to teach and mentor engineers. Make them productive while giving room to innovate. Read other's code before designing/writing the new thing. Simplifies religiously. As an engineer: enjoys solving hard engineering problems and even more creating value. Unafraid of deep dives into the technology stack. Writes code simple enough that can be debugged later. Specialties: transforming chaos into order, optimizing costs on AWS, microservices, hiring, big data, security, data mining, algorithms, debugging, full-stack prototyping, 0 to 1, 1 to 1024, bringing new products to the market, starting new engineering teams and offices All views are my own.

Sumo Logic

Director of Engineering

From early employee pre-revenue to $2Bln+ Initial Public Offering (NYSE:SUMO). Major accomplishments: 1. Created the Sumo Logic Warsaw office (~70 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. 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.
