Summary

I’m a software engineer specializing in functional programming using strong static type systems, in Haskell in particular. I have worked many years as a full-time consultant helping our clients design and build correct, robust, and maintainable software. Being a consultant allowed me to participate in more projects that a typical software engineer gets to work on. I’ve developed the ability for critical thinking, making wise trade-offs, analyzing and exploiting advantages of various technologies to satisfy needs of business. I also learned how to handle different personalities and collaborate with diverse teams. My personal projects include high-profile Haskell libraries, tutorials, and a technical blog.

Professional experience

January 14, 2019–present. Senior software engineer at Tweag, Paris, France. Working as a consultant most part of the time, but also building OSS, writing blog posts, doing interviews for new hires, etc.
January 25, 2018–January 11, 2019. Software engineer at Tweag (remote). Worked as a consultant with a number of clients, helped developing Bazel rules for Haskell.
