👤
SeniorMirek Sedláček is a Lead Developer with over 18 years in software delivery and nine years focused on leading teams, currently heading the GOL Internet Booking Engine used by travel agencies across Central and Eastern Europe. He combines end-to-end product ownership—from business negotiations and estimations to design, testing, deployment and maintenance—with hands-on coding in PHP, JavaScript, Python and SQL. Mirek has scaled his team from 5 to 30+, instituted smaller cross-functional groups, and drives hiring, retrospectives and 1:1 coaching to improve performance and morale. Deep domain expertise in booking engines and payment gateways is complemented by practical API integrations (Travelport, TravelFusion, GTA, ERV) and infrastructure work with AWS, Docker and CI/CD. He is an early advocate of AI-assisted development, running weekly AI check-ins and experimenting with tools like OpenAI, Gemini and Claude to speed delivery and knowledge sharing.
