Top SchoolLeonardo Otero is a Sr. Fullstack Developer with 13 years of experience building cloud-native, event-driven systems and consumer-facing web applications from Buenos Aires. He blends hands-on front-end expertise (React, Next.js, Gatsby, Ant Design) with robust back-end and infrastructure skills (TypeScript, Serverless, AWS Lambda, SQS/SNS, EC2, Snowflake), often owning integrations between serverless functions and data warehouses. Leonardo has led and mentored squads, designed microservice architectures, and driven performance improvements—such as implementing MongoDB Atlas Search and Redis caching to speed real-time features. His background spans fintech and payments to scholarship and e‑learning platforms, and he’s delivered complex bank integrations and multi-tenant feature work across several high-impact sites. Notably, he moved from maintenance and tuning roles early in his career to architecting CI/CD, observability, and data pipelines that scaled across dozens of bank integrations. He combines pragmatic technical leadership with deep operational knowledge, enabling teams to ship secure, observable, and performant systems.
