Aunmoy Dey
Over deze dienst
Bring AI into your productwithout building the infrastructure from scratch.
I help startups and SaaS teams integrate AI using OpenAI, RAG, vector databases, and production-ready backends. Whether you need a chatbot, smart search, document assistant, or AI workflow, I build reliable, scalable solutions that work in production.
What I can help with:
- AI chatbots & assistants (OpenAI, Claude, Gemini)
- RAG with pgvector, Pinecone, ChromaDB
- Semantic search, document chat, embeddings
- AI agent backends (LangChain, LangGraph, MCP)
- LLM gateways, model routing, prompt mgmt
- AI evaluation, token tracking, cost optimization
- Backend APIs (REST, GraphQL, gRPC)
How we work:
1. Understand your AI use case and data
2. Design AI architecture (gateway, vector store, caching)
3. Build, test, iterate with regular updates
4. Deliver production-ready system with deployment guidance
Why me?
- Backend engineer treating AI as infrastructure, not just prompts
- Clean, scalable designno glued-together demos
- Real experience with LLM gateways, RAG, and evaluation
- Clear communication, reliable delivery
Message me your AI idea. I'll outline the simplest architecture before you order.

I help startups and SaaS companies build backend systems that scale and integrate AI—without the rewrites.
You get production‑ready Golang & Node.js microservices, event‑driven architectures (Kafka, Redis), Kubernetes deployments, and AI integrations (OpenAI, RAG, agents). I've built logistics platforms, payment systems, and real‑time AI pipelines.
How I work:
→ Backend‑first, clean architecture
→ Regular updates, no surprises
→ Code that's easy to maintain and extend
Message me your project idea. I'll outline the simplest, most effective approach before you order.
