At DataArt, I built content versioning and scheduled publishing so administrators could prepare and publish news and promotions in bulk. I also implemented locale-aware caching and improved CI pipelines.
At Symmetre, I optimized spreadsheet import queries, reducing processing time from 1 second to 250 milliseconds. I also automated general ledger integrations with ERP systems and contributed to financial calculation performance improvements.
At Umbrellio, I developed a payment widget and transaction analysis dashboards, and helped migrate payment processing and fraud prevention functionality to microservices. I use Ruby on Rails, PostgreSQL, Sidekiq, and RSpec to build transaction-heavy systems, APIs, and integrations, with a focus on correctness and production safety.
