Pavlos Karageorgiadis.

Software Engineer · Stockholm

Hi, I’m Pavlos.
I build web products people enjoy using.

Software engineer at LeoVegas since 2020, working across React, TypeScript, Node.js and GraphQL — from gamification features in the casino to building a new sports vertical. I care about scalable code and the small details that make a product feel right.

Experience

  1. Software Engineer

    LeoVegas · Stockholm, Sweden

    2020 — Present
    • Building web products with React, Next.js, TypeScript and Node.js microservices — GraphQL and REST APIs, MongoDB — deployed on Google Cloud with Docker, GitHub Actions and Jenkins.
    • Casino domain: designing and shipping gamification features for players.
    • Sportsbook: building features and helping launch a new sports vertical.
    • Testing with Jest, React Testing Library and Playwright; monitoring with Grafana and Datadog.
    • Run the team’s agile process — plannings, retros and day-to-day organisation — alongside the engineering work.

  2. Earlier: IT & networking

    Before moving into development I worked on the infrastructure side — IT Administrator at LeoVegas (2017 – 2020, office infrastructure, cloud tooling, on-boarding) and IT Technician at Cyta Hellas in Athens (2016 – 2017, broadband and VoIP support). It’s where I picked up the networking background and the habit of caring how things run in production.
