Backend Engineer at Digital Geosciences building NestJS APIs and PostgreSQL schemas for backend services.

At Digital Geosciences, I designed and implemented RESTful APIs using NestJS, TypeScript, and Node.js. I also built and optimized PostgreSQL schemas and queries, and containerized services with Docker.

For FundChain, my graduation project, I developed backend REST APIs and an SQL Server database for a blockchain crowdfunding platform, integrating Node.js services with Ethereum smart contracts. I’m currently focused on backend engineering, API design, database architecture, testing, and maintainable systems.
