Top SchoolSpiros Vathis is a Principal Software Engineer based in Greece with over two decades of hands-on experience designing and implementing high-performance, data-intensive real-time systems across Solaris, FreeBSD, Windows and cloud platforms. He has led teams of up to 10 engineers to deliver network and security features at Citrix—consolidating SD-WAN routing and on-appliance security—and driven major performance refactors that increased analytics ingestion by an order of magnitude.

His mathematical background underpins an analytical approach to debugging, performance tuning and dissecting large legacy codebases to quickly deliver outcomes. Notably, he taught himself Python mid-career to ship production-quality Azure integrations and championed moving teams from entrenched legacy tech to scalable platforms like Node.js and NoSQL. He pairs technical mentorship and hiring experience with a track record of translating complex requirements into efficient, deployable solutions for operators and enterprise customers.
