About

I’m Pavlo Lazunko, a system architect, team lead, and CTO with a passion for building scalable software and leading high-performance engineering teams. I design architectures across imperative, declarative, and mixed paradigms, and I apply DRY, SOLID, and SLAP in practice. I have led initiatives in payments, ERP/CRM, corporate messaging, and real-time streaming with WebRTC and WebSockets.\n\nBeyond coding, I mentor engineers, conduct technical interviews, and align technical direction with business goals. I’m skilled in cloud infrastructure, microservices, and DevOps, and I enjoy turning complex problems into maintainable solutions that scale.
