Report

Software architect, product engineering team architect, distributed systems enthusiast, clean code lover, very average table tennis player. I can act as Engineering Manager, Staff Engineer or Senior Software Engineer.I am currently most interested in digital products software delivery. I thrive in Product-oriented organizations and I love to build teams with strong customer empathy. I'm currently interested in explorating outcome-oriented engineering.I usually work (but not only) with Golang, Kotlin, Java, TypeScript, or PHP. I'd also love to work more with Rust.Authors References:- Charity Majors and her blog- Team Topologies by Matthew Skelton- The Manager's Path by Camille Fournier- Staff Engineer by Will Larson- An Elegant Puzzle by Will Larson- The Pragmatic Engineer from Gergely Orosz
