Konstantinos
Voulgaropoulos Software Engineering Manager

Engineering manager who builds. I came up through tax audit, taught myself to code because I wanted to turn ideas into real software, and have spent the last five years at Deloitte leading a team of engineers and owning a portfolio of production-grade internal applications. What sets me apart is the combination of finance and tax domain depth, full-stack engineering fluency, and the ability to take a fuzzy business problem all the way through to a live product — covering requirements, architecture, and delivery without handing off at any stage.
