You will get AI translation SaaS with RAG, multi-agent & Stripe
Project details
I deploy production-grade Java backend infrastructure for AI-powered SaaS platforms. Built on NovelTrans — my MIT-licensed open-source translation system — you get enterprise architecture without vendor lock-in or recurring license fees.
I specialize in Spring Boot, Docker orchestration, database design, REST API development, and third-party integrations (Stripe, LLM engines). The web dashboard and Chrome Extension are delivered as functional layers that communicate correctly with the backend, but I do not provide UI/UX design or CSS customization.
Three packages available:
• Starter ($300): Core backend deploy on your VPS
• Standard ($600): + Stripe billing & extension functional layer
• Advanced ($1,200): Custom backend engineering & full deploy
You own the full source code. I provide the expertise to make it production-ready.

About Bing
Full-Stack Developer | Spring Boot, AI Integration, Stripe, React
Chengdu, China - 4:23 pm local time
It replaces the "copy-paste into Google Translate" workflow with an intelligent 4-tier translation pipeline: (L1) Caffeine→Redis→MySQL distributed cache with cross-instance consistency; (L2) RAG semantic search via Redis HNSW vector index (cosine ≥ 0.85) that skips LLM calls and cuts API costs by 60–80%; (L3) entity-consistency pipeline using SHA-256 placeholders to lock character names across chapters; (L4) multi-engine AI orchestration with probability-based load balancing across Python FastAPI and local MTranServer, plus bidirectional failover.
Other production features: multi-agent collaboration (3 agents per chapter with genre-matched prompts), Stripe subscription billing with 3-level idempotency (webhook signature → Redis SETNX → MySQL optimistic locking), per-user semaphore concurrency control + sliding-window TPM rate limiting + monthly character quota enforced by Lua atomic script.
Quality & Performance: strict hexagonal architecture (domain layer zero framework deps), 80.6% test coverage (JaCoCo, 115 test files), k6 load tested at 200 VU — 1,140 req/s (Mock) / 792 req/s (Real), P95 292ms, 100% pass rate, 0 HTTP errors.
Steps for completing your project
After purchasing the project, send requirements so Bing can start the project.
Delivery time starts when Bing receives requirements from you.
Bing works on your project following the steps below.
Revisions may occur after the delivery date.
Environment audit
Verify your VPS, domain DNS, and API credentials (OpenAI/LLM endpoint, Stripe keys for Standard/Advanced). I confirm server access before deployment begins.
Docker deployment
Build and launch all containers via Docker Compose: Java Spring Boot backend, MySQL 8.0, Redis Stack, Nginx reverse proxy, and Python translation microservice.
