Juan Carlos Valencia López

I'm a Senior Full-Stack Developer with over 8 years of experience designing and shipping complete web products, from frontend interfaces to backend infrastructure. I work primarily with TypeScript, React and Next.js on the frontend, and Node.js, NestJS, and Go on the backend, building REST and gRPC APIs on PostgreSQL and MongoDB with event-driven architectures deployed on AWS, Azure, and GCP. Most recently, I designed and built a multi-tenant SaaS web-monitoring platform with AI-generated insights, architecting hexagonal modules, a Turborepo monorepo frontend in Next.js, and background job processing with BullMQ, along with real-time notifications and OAuth-based authentication. I've also built hierarchical content management systems with Google Drive integration, enterprise microservices platforms on Azure AKS with Kafka and Service Bus, and client-facing products with React, Vue, and Laravel. I care about clean architecture, maintainable code, and production stability, and I enjoy mentoring teammates through code reviews. I'm looking for a senior or lead remote role where I can own features end-to-end, collaborate with async-first teams, and keep growing into system design and DevOps practices.
