Lester
Arteaga.
I'm a professional freelance
Senior full-stack developer with 9+ years delivering scalable, high-performance applications in Node.js, TypeScript, React.js, and Next.js. I design and operate cloud architecture on AWS (ECS, Fargate, EC2, Route 53, CodePipeline, Pinpoint) and lead engineering teams as Tech Lead, Project Manager, and Scrum Master—combining technical depth with agile delivery and a focus on product quality.
About me
I'm driven by building products that scale and last—from e-commerce and insurance platforms to internal tools and AI-assisted apps. I like to go deep on both code and architecture, and I get as much satisfaction from shipping clean features as from helping teams level up. Whether it's leading a squad or pairing on a tricky bug, I focus on clarity, quality, and delivery.
