MexicoWhat I'm looking for
I am a Fullstack Developer with 10+ years building and maintaining web applications end-to-end, with deep expertise in .NET C# and modern JavaScript frameworks such as React, Vue and Angular.
Over the past five years I have focused on Node.js and React, delivering production-ready REST APIs, SPAs, and component-driven architectures for high-volume e-commerce and transactional systems.
I have 4+ years working with AWS services (EC2, S3, RDS, CloudWatch, IAM, Load Balancers) and 5+ years supporting production environments, deployments, monitoring and incident response.
I thrive in startup and lean-team environments where I own design, development, deployment and support. I leverage CI/CD, Docker, monitoring tools and AI coding assistants to improve quality and accelerate delivery.
