Esteban De Salas is a pragmatic full-stack engineer with 12 years’ experience building rich front-ends, RESTful APIs and backend automations, currently based in Madrid. A lifelong coder (started on a ZX Spectrum), he combines hands-on delivery—microservices, event-driven architectures, Node.js, and cloud/DevOps—with strong communication and community leadership (Top 2% on StackOverflow, 1000+ GitHub stars, runs workshops and writes technical articles). He has delivered across mobility, IoT, payment and financial reconciliation systems, and is comfortable spanning databases from MongoDB and DynamoDB to Postgres and MSSQL. Equally at home prototyping hardware interfaces as he is designing OAuth-secured APIs, he enjoys hackathons and turning complex workflows into simple, reliable automations. Currently exploring blockchain, Rust, Web3 and container orchestration, he blends practical product focus with a curiosity for emerging stack-level technologies.
