Senior🎓
Top SchoolMarcelo Tokarnia is a Principal Software Engineer with 12 years building scalable web platforms across payments, e-commerce and HR tech, currently driving backend and architecture at Comp in Stockholm. He is a pragmatic polyglot (Node/TypeScript, Python/Django) who prefers backend systems, testable designs and maintainable microservices while still shipping front-end integrations when needed. Marcelo has led payment-platform abstractions and monorepo architectures at Klarna, migrated large multitenant systems to single-tenant microservices, and implemented streaming downloads of multi-gig datasets in AWS—demonstrating both operational and architectural chops. He is passionate about code quality, refactoring and team protocols, and enjoys mentoring engineers and turning collective learning into better product design. An engineer who documents and tinkers publicly via his personal playground and blog, he brings a thoughtful balance of hands-on implementation and systems thinking to complex problems.
