Summary
👤
Senior🎓
Top SchoolKrisztian Lachata is a Principal Software Engineer with two decades of hands-on experience designing and delivering scalable, resilient backend systems across Scala, Java and increasingly TypeScript/Node.js. He has led teams and technical designs for Kafka-driven, event-first platforms and applied domain-driven and hexagonal architectures to reduce operational costs and customer dropouts in high-stakes production environments. At OVO he steered onboarding and billing transformations that balanced developer ergonomics with measurable business impact, and earlier roles at eBay, Sky and Gamesys show deep expertise in data-heavy microservices and high-concurrency systems. Comfortable both as a team lead and a pragmatic coder, he pairs cloud-native toolchains (AWS/GCP) and typed languages with a continuous-learning mindset—currently preparing for AWS Solutions Architect Professional. Based in London (British citizen) he prefers remote or hybrid roles but regularly collaborates on-site when it accelerates delivery.
