Angelo Niño Aguilar

I’m a Full Stack Engineer who builds and maintains complex applications with a strong focus on security, scalability, and maintainability. I partner with stakeholders and teams to translate requirements into reliable systems that perform under real-world constraints.

Across recent contracts and freelance work, I’ve designed and developed microservices, built production-ready APIs, and strengthened system performance through careful troubleshooting and code review. I also integrate third-party services—such as Stripe payment acceptance—and apply automated testing practices to keep delivery dependable.

In larger product environments, I’ve pioneered core backend capabilities for large-scale platforms, including building domain APIs (balances, debits, reversals, refunds). I’ve managed API gateway setups, implemented OAuth-based access patterns, led PR reviews, and documented processes to improve team consistency and release quality.

I’m hands-on with modern stacks spanning Node.js, React/Next.js, Python, .NET, and multiple database systems, and I’m comfortable working across Dockerized and Kubernetes-based deployments. My professional ethos is simple: write clean, testable code; automate where it helps; and ship solutions that are measurable, secure, and easy to evolve.
