About Lev Alexandrovich N.

Lev Alexandrovich N. is a Software Engineer at Galileo πŸ”­. Colleagues describe them as "I worked with Lev at Doordash. Lev led the design, scoping, execution and adoption of a standardized multier cache at Doordash. My team benefitted from Lev's cache. My team's mission critical microservice cut down latencies 10x from 100ms to 10ms. In his design, Lev thought out the common problems with caches chiefly, staleness, inconsistencies, over dependence on redis and lack of observability. He built a simple interface leveraging the cache to solve scalability issues for multiple services across Doordash. His solution included runtime controls enabling incident free rollouts. The standout characteristic about Lev was his conviction with which he led the adoption of the Cache across Doordash, making a massive impact across the ecosystem.", "Lev is one of the passionate and outstanding engineer that I have worked with. His drive to finish the work that he takes over is something that is really impressive. It doesn't matter the time and place, I always find Lev always on it until it gets done. He contributes a lot to complex problems in the organization which include cache management, data consistency across systems. There are incidents when Lev foresaw major blockers and have the fixes ready. I remember once when his prediction came true and he already has a fix that he worked on by himself even though he was pushed backed continuously on that solution. He saved the day during that incident, which would have had dire consequences if not for the fix that was ready to go. I worked a lot with Lev and its always fun and exciting to work with him. He helped me out during incidents when I needed help and he surprised me with the effort he put, helping me out. He is very passionate with the ideas he has and he is not scared or hesitant to take criticism .This is something I like the most in him. Together we had great conversations related to tech and its always interesting to have conversations with him. He is definitely a rock star in our team and organization.", and "Lev is an outstanding engineer and individual contributor. He's had major contributions to our message processing and content assignment infrastructure, tackling incredibly difficult problems like distributed cache coherency, data consistency, and various performance optimizations on services with traffic well over 30k requests per second. Lev's dedication to solving the problem in front of him is second to none as he'll spend weekends and nights driving whatever he picks up to completion. He's also been a great teammate, often helping other engineers get unblocked and mentoring a summer intern."
