Rockstar🎓
Top SchoolAlexander Leitner is a senior software engineer with 12 years of experience building systems in C and Go, currently contributing to Apache Guacamole at Keeper Security and maintaining core pieces of the Storj decentralized storage stack. He has deep hands-on experience across embedded, cloud-native microservices, and distributed storage—implementing low-level C features, Go piecestore logic, and RPC/bandwidth tooling while also improving front-end UX in desktop and web projects. Comfortable across languages and environments (C, Go, Node, PHP, Scala, Solidity), he pairs systems-level debugging with pragmatic product thinking to ship reliable infrastructure. He’s contributed notable fixes to high-profile open-source projects like apache/guacamole-server and storj, including RDP/SSH session hardening and newline/clipboard normalization that improve real-world interoperability. Based in Atlanta, he brings a linguistics background and multilingual context (Japanese experience) that supports cross-cultural engineering and clear technical communication. Outside work he’s interested in linguistics, Magic: The Gathering, and cats—hints of a curious, detail-oriented problem solver.
