You will get I will build a REST API with Python or Java Spring Boot
Project details
You will get a clean, documented REST API built with Java Spring Boot or Python — ready to integrate with any frontend, mobile app, or third-party service. With 2+ years of backend engineering experience and published AI research, I build APIs that are scalable, secure, and production-ready. Every delivery includes working endpoints, basic authentication, and a Postman collection so you can test immediately. I respond fast, deliver on time, and explain everything clearly — no technical jargon unless you want it.

Claude Certified ✅ LangChain Certified ✅
PhD AI Researcher & Software Engineer | Agentic AI · LangGraph · MCP · RAG · Spring Boot | Zapier | n8n | Skill creation | AI-ML-DL
From autonomous AI agents to LLM-powered backends and scalable microservices, I combine research-level AI understanding with real-world engineering to deliver complete, production-ready solutions.
I'm a PhD researcher in Artificial Intelligence, certified in LangChain, LangGraph, and LangSmith, with hands-on experience building agentic systems, RAG pipelines, and intelligent backend architectures. My research is published in peer-reviewed journals (impact factor up to 4.9), so I don’t just use AI — I understand how it works under the hood.
At Devticks, I design and maintain production-grade microservices using Spring Boot, Kafka, and Docker — ensuring systems are scalable, reliable, and built for real-world usage.
