Portrait of Štefan Hudáč

Štefan Hudáč

DataX Computing, spol. s r. o.

Computer Software Consultant and Contractor

Technology entrepreneur and full-stack developer with over 30 years of experience building software, leading development teams, and delivering business-critical IT solutions. My expertise spans cloud infrastructure, software architecture, automation, DevOps, and modern web technologies, with a strong focus on AWS, self-hosted systems, and open-source tools. I’m particularly interested in AI, practical applications of AI-assisted development, and emerging technologies that challenge conventional approaches. Naturally curious and hands-on, I enjoy exploring how things work, connecting ideas across disciplines, and turning complex problems into elegant, reliable solutions. I believe in continuous learning, pragmatic engineering, and using technology to create real value.

Profiles

The story

  1. 1996

    Independent developer

    I have built software professionally since 1996, first as a self-employed developer.

  2. 2000 – 2004

    New York

    I spent four years in New York on e-commerce and early mobile web projects built on WAP — at a time when both fields were still taking shape.

  3. 2009

    DataX Computing and the VÚB group

    I incorporated DataX Computing in 2009 for a contract with Consumer Finance Holding (CFH), VÚB bank’s subsidiary for consumer loans and instalment sales. VÚB is today the second-largest bank in Slovakia by total assets.

    I led the team that took the systems from the Slovak crown to the euro. Slovakia adopted the euro on 1 January 2009.

  4. 2018

    Working for VÚB directly

    When CFH merged into the bank on 1 January 2018, I moved to working for VÚB directly. I led the team that moved the entire internal software estate onto virtualisation and containers.

  5. 2022

    Reactoo, London

    After 2022 I worked with Reactoo, a London start-up, on its cloud platform for live video.

The company

Smaller projects I take on myself. When a project needs more people, I put a team together and stay accountable for it — as I did in the VÚB group.

Docker Swarm

The same compose file on a laptop and on a swarm
