Senior🎓
Top SchoolPeter Guerzenich-small is a Principal Software Engineer with over three decades of experience designing pragmatic, user-centered software and data systems, and 14 years in senior engineering roles delivering production-ready products. He blends hands-on coding (often two-thirds of his time) with technical leadership—leading teams, architecture steering committees, and cross-team integrations—to ship revenue-driving features like a Product Led Growth microservice that cut API latency from 1.5s to 12ms. Fluent in Scala, Java, JavaScript, C#, and experienced with Go, TypeScript, microservices, pub-sub IoT architectures and AWS, he has moved legacy monoliths to modern microfrontends and built mission-critical systems for shipping container scanners and SaaS backup. A physicist by training (MS, Colorado School of Mines), he brings a systems-thinking, measurement-driven approach to UI design and data visualization and has deployed solutions in remote, regulated environments worldwide. Notably, he pairs deep protocol and performance work (AMQP/RabbitMQ, Protobuf) with front-end craftsmanship, multilingual UIs, and practical tooling for operations and migrations.
