Aljen Magat

I am a senior full-stack and DevOps developer with around 7 years of experience building web apps, mobile apps, internal systems, APIs, automations, and cloud-based products. My main stack includes React, Next.js, Node.js, TypeScript, Python/FastAPI, Golang, Laravel, PostgreSQL, MongoDB, Redis, Docker, AWS, and CI/CD pipelines. I can handle projects end-to-end, from planning and architecture to frontend, backend, database, deployment, monitoring, and production support.

I usually work closely with product, managers, and operations teams to understand the real business workflow, then turn those problems into practical software solutions. My strongest areas are modern full-stack development, backend systems, DevOps, AI integrations, internal tools, CRM automation, and performance optimization.
