Hi there 👋 I'm a developer passionate about building great products, writing efficient code, and understanding complex systems. I mostly code in Ruby and Elixir, and occasionally use Go, JavaScript, and Rust.

• 🐶 Datadog: I work as a Ruby library developer at Datadog. Currently I am leading efforts to create a CI visibility Ruby library (datadog-ci gem) and acting as a maintainer and contributor for Datadog tracing library ddtrace.
• 🛍️ Shopify: I led a team of 3 backend developers to build order management functionality for the Shopify Bundles app. We released the app in public beta and it is expected to be used by thousands of merchants. I also performed a deep dive on performance issues and discovered a garbage collection problem in the main Ruby on Rails monolith that powers Shopify.
• 🚗 SHARE NOW: During the COVID-19 lockdown, I helped our engineering organization to mature and invest in building a competitive advantage for the future post-pandemic. I implemented a dynamic pricing system that increased fleet utilization by 20%, resulting in a 10% increase in profits over the holiday season. I also ensured the internal systems powering SHARE NOW were robust by rewriting the Vehicle Location Tracker, improving its maintainability and resilience.
• 🏗️ kloeckner-i: I built Part Manager e-commerce app, which allowed clients to manage their steel contracts online. By utilizing the tools for concurrent data import provided by the Elixir language, I achieved a 6x increase in data import speed.

• 🌍 Traveling is my favorite hobby, so I am creating Hamster Travel - the only travel planner I need - to make it even better.
• 🎮 Video games is another hobby of mine, and I developed Igroteka to keep track of my gaming backlog.
