Karol Bąk is a pragmatic CTO and software engineer with over a decade of experience turning early-stage ideas into production-grade web products, currently leading Measure Studio’s tech and AI efforts. He combines deep Ruby on Rails expertise with front-end (Vue.js), cloud (AWS, Heroku, DigitalOcean), and data work (Postgres, Redis, ClickHouse) to ship performant, secure applications and analytics pipelines. Comfortable in fast-changing startup environments, he’s led recruitment, built teams from scratch, and navigated large legacy codebases while keeping a "build fast, fail fast" mindset. An advocate of test-driven development and CI/CD, he also contributes open source libraries and mentors engineers, with his blog featured in Ruby Weeklies. Less obvious: he pairs hands-on backend performance tuning with practical AI pipeline integrations, bridging classic web engineering and emerging ML needs. Based in Krakow, he brings both product-focused leadership and continual hands-on coding to scale analytics products.
