...Sales, order bookings, and logistics processes still rely on too much manual touch. • Data travels through a CRM system, an inventory platform, WhatsApp conversations, and legacy tools such as Navision and Busy. Right now each hand-off is a bottleneck. What I expect from you You’ll design and code the entire backbone: secure REST endpoints, clean front-end hooks (React or similar), and microservices or serverless functions that talk fluently with every API in play. Python or Node.js is fine, provided the approach supports quick iteration and future hand-off. Where rule-based logic isn’t enough, I want small, focused AI agents—think LangChain, OpenAI, or similar libraries—making routing and decision calls. Key deliverables 1. Unified automation...

I’m building a production-grade web application and need a seasoned full-stack Java developer to drive the effort from architecture through deployment. The back-end will be written in modern Java with Spring Boot at its core, using Hibernate for ORM and a microservices design to keep the codebase modular and scalable. You’ll own everything server-side: designing RESTful endpoints, modelling the database, securing the APIs, writing unit and integration tests, and containerising the services for smooth deployment. If you prefer bringing your own front-end stack, that’s fine—Angular experience is certainly welcome but not essential, as long as the UI integrates cleanly with the services you expose. When you respond, focus on the depth of your experience de...
