Top SchoolRobert Lebel is a Senior Software Engineer based in Boston with 10 years of hands-on experience building backend systems and developer tooling. He holds a BS in Computer Engineering from Northeastern and has progressed from support and engineering roles to leading internal platform efforts at Klaviyo. His recent work focuses on FastAPI services that power a company-wide internal app platform used by 600+ weekly active users and Python CLI tools that integrate AI into dev workflows, improving token efficiency and response times. Robert combines deep troubleshooting experience across databases, networking, and multiple languages (C/C++, Java, JavaScript, SQL, Caché ObjectScript) with practical product-driven engineering. He’s equally comfortable optimizing developer experience as shipping customer-facing features, and often bridges gaps between ops, QA, and engineering to get complex systems into production.
