Hi 👋
I'm Lukas - a senior software engineer passionate about building useful stuff.
My day_job
is designing & implementing edge computing platform for a CDN. I make Wasm go brrrr
under 50 Tbps of traffic on 1.5k+ servers. I'm essentially modifying Nginx code to be able to execute Wasm fast.
Using Rust, C and Lua.
For the past six years of my professional experience, I have worked mainly with Kotlin, C#, Java, Python, Rust, C, Lua and Typescript, with some small projects in Go. In the past, I primarily worked with Kotlin and lately with Rust and C. I enjoy working on the backend services, but I can do quite a lot in React and Vue.js, although I'm pretty bad at CSS.
During the time I worked with Kotlin, I created some small libraries such as Katlib, Exposed Upsert and Ktor Plugins. Now I'm trying to find time to simplify working with multiple calendars at once with Camerge.
In the past years, I worked in Wire, where I lead a team working on Wire for Teams and another working on modular MLS backend. I also helped to bring to life many Wire's libraries such as Cryptobox4j, Xenon, Helium, Lithium, Roman, multiplatform Kalium and a lot of Wire integrations created in Kotlin, Java, Python, and even Deno. Last but not least, I was also working on our billing system and managing two K8s clusters and do a lot of DevOps, automating everything with GitHub Actions, Docker, and Helm.
I co-founded Mild Blue, where we're building cool things based on the latest research for hospitals. I helped to create covid-vaxx, TXMatching, and a lot of other things that, sadly need to stay closed source. I've worked on Python, Java, Kotlin, C#, and PHP backends and mobile apps in Ionic, React Native, and Flutter. I also created some native plugins in Swift and Kotlin and managed our infrastructure on AWS with Terraform. I sold most of the shares in 2022 and nowadays I'm consulting challenging technical problems and business solutions.
Before all of that I worked in Blindspot on AI solutions - mostly using Kotlin, Python and C#.
I firmly believe that we should make the internet more secure & private, and that's why I help people from StratosphereIPS with their Slips. I'm also Teaching Assistant at FEE CTU helping with master's coures Introduction to Cybersecurity.
