Top SchoolDeivydas Ziziliauskas is a backend engineer with 10 years’ experience specializing in Ruby on Rails, performance tuning, and large-scale data processing. He has built customer-facing features that surface aggregated statistics from massive datasets and optimized APIs, queries, and Sidekiq workflows to keep systems responsive under load. At SmartrMail he engineered heavy-data integrations with major e-commerce platforms and managed cloud migrations between GCP and Azure, and at Hypofriend he helps power a mortgage recommendation engine that scans thousands of products.
