Miguel Santyos

I’m a Software Engineer who thrives in building startups from the ground up, no matter the industry. I’ve led the development of sleek, high-performing web apps that scale—working remotely with global teams to deliver exceptional user experiences.

Most recently at Popstand, I led a high-performance Next.js application, achieving a 97% PageSpeed score through optimization, SEO improvements, and AWS infrastructure setup. I architected and deployed microservices with NestJS, Golang, and MongoDB, and implemented API documentation with Swagger plus CI/CD using GitHub Actions.

I’m also focused on reliability and measurable outcomes: I improved scalability and observability with Kubernetes and Istio, reduced API response times by 60% through query optimization and caching strategies, and built secure authentication with JWT and OAuth2 to ensure GDPR compliance. I use Jest and Cypress to keep quality high, and I mentored junior developers—reducing bug reports by 40%.

Earlier, as a Senior Full Stack Engineer at Craft&Crew, I improved team productivity by 30% with an AI-powered task prioritization system using Angular and RxJS, handled 50K concurrent users with WebSocket live updates, and reduced development time by 40% with a reusable UI component library backed by NgRx. I’ve also built and maintained multiple production web applications using React, Angular, Vue, Laravel, and MongoDB, with automated deployment and monitoring using Docker and cloud services.
