Leonardo Menezes is an engineering leader with 10 years of experience building and scaling payment and customer-service platforms across fintech and consumer tech. He has led teams at Apple, Spotify and Klarna, shipping new payment products and mission-critical tooling used by support organizations and millions of customers. Comfortable both as a hands-on engineer (Java, Python, C#, Postgres, Kafka) and as a people manager, he has repeatedly taken features from prototype to multi-country production. At Spotify he owned tooling tied to one of the company’s largest operating expenses, and at Klarna he launched and scaled Fixed Terms and Slice-it payment methods. Based in Stockholm and trained at the Federal University of Rio de Janeiro, he blends technical depth with operational focus to simplify complex integrations and platform experiences. His public portfolio (ltmenezes.dev) highlights a practical emphasis on reliability, observability and developer ergonomics.
