Summary
👤
Senior🎓
Top SchoolOscar Sánchez is a Senior Software Developer based in Madrid with eight years’ experience building full-stack web applications, APIs, and scalable backend systems. He blends strong C# and TypeScript skills with practical DevOps and AWS experience, having led projects that processed invoices for millions of users and delivered production-ready services using serverless architectures. Comfortable across the stack and product lifecycle, he has worked in hexagonal-like architectures, authored user stories as part of product teams, and taken ownership of end-to-end solutions for startups and agencies. Early work in security and ethical hacking informs a pragmatic approach to robustness and threat-aware design, and his background includes hands-on experience with pentesting tools, biometrics, and CI/CD automation. Colleagues know him as an engineer who loves experiments and PoCs—equally at home refactoring legacy systems or hacking together quick proofs to validate ideas.
