    I need an experienced web developer to recreate an existing site I will share once we connect.

    I run an ongoing web application project built on Java 17, Spring Boot, and the latest Angular stack. The codebase is healthy, the backlog is full, and I need an extra set of expert hands during standard USA working hours. If you already have a daytime role but can reliably commit to a second engagement, this collaboration should fit you perfectly. You will pair with me to extend existing micro-services, refine Angular components, create REST endpoints, and tighten unit and integration test coverage. Clean, well-documented code and frequent Git commits are a must; I review in real time while we overlap online, so clear communication matters as much as technical skill.

    I’m forming a small founding team and want a business partner whose strengths lie in intermediate-level backend development.
