Job experience

Apr 2016 - Jun 2023 Uber. Senior engineer in the Observability organization. Mostly worked on developing On-Call Experience tooling, but also touched host-level monitoring and logging platform.

Our team was developing and maintaining several web applications integrated with various observability tooling that exposed the available diagnostic material to the on-call engineers (used by thousands of engineers across the entire company), as well as allowing them to systematically improve their process.

As a senior engineer I had wide range of responsibilities in the team. Working on the software components that I owned, I did the entire lifecycle: wrote the architecture documents, led the work on implementation, provided the documentation and finally, maintained the system after launch.

On the people side, my responsibilities ranged from interviewing people, to helping them onboard smoothly, to growing more junior engineers along their careers.

Also worked on improving host-level monitoring scalability. The monitoring tools we were using at the time weren't meant to monitor hundreds of thousands of servers, so extra layers of tooling was necessary while other solutions were evaluated.

Worked on several features improving the logging platform on the scale of ingestion of millions of lines per second and storing several petabytes (

Dec 2012 - March 2016 Bentley Systems. Worked in mobile department. Developed engineering and construction software for handheld devices for use in the field.
