I will build your java spring boot backend API
Yu Bing
About this gig
I will deploy your Java Spring Boot backend and API infrastructure on Docker production-ready and fully configured.
Built on NovelTrans (my MIT-licensed open-source SaaS), you get enterprise-grade architecture with zero vendor lock-in and no recurring license fees. I specialize in backend engineering: Docker Compose orchestration, MySQL/Redis setup, REST API tuning, Stripe billing integration, and Chrome Extension MV3 communication layers.
Packages:
Basic Core system deploy: Java backend, database, Redis, Nginx, default web UI.
Standard Everything in Basic + Stripe Checkout & Billing Portal, extension functional layer, API validation.
Premium Custom backend APIs, three-tier cache tuning, concurrency/Resilience4j config, full deploy + 2h handover.
Important: I deliver functional frontend that communicates correctly with the backend. I do not provide UI/UX design, CSS customization, or branded page layouts.
You need: Ubuntu 22.04+ VPS (8GB+ RAM), domain name, OpenAI API key (or local LLM). Standard/Premium require a Stripe account.
You own 100% of the source code. I provide the deployment expertise.
Message me before ordering to confirm your server environment is ready.
