Bio
Javier Sagredo Tamayo
Working with Lukasz was a delightful experience. His pragmatism and will to write clean and high performant code were some of his most valuable characteristics. Always up to date with what was happening in the Rust world and confident to embrace changes when done for good reasons. Also a fruitful contributor to open source code as the Rust compiler. Would recommend working with him 10/10 times.
