I build production web applications end to end: database, API, and interface. Java/Spring Boot or Node/NestJS on the backend, React and TypeScript on the front, deployed on AWS with proper CI/CD

.This suits you if you need a working product rather than a prototype: real authentication, an audit trail, tests, and documentation you can hand to the next engineer. I have built this shape of system for health insurers, banks, government, and a satellite operator, so I am comfortable where correctness and uptime actually matter.

Typical engagements run two to six weeks for a defined scope, or two to four months for a full platform. Fixed fee, milestone-based, so you know the cost before we start.
