Nahom K.

Hi, I’m Nahom Keneni, Senior back end and AI engineer. I build reliable, scalable backend systems and intelligent AI solutions. My work combines strong backend engineering expertise in Go, Python, Django, FastAPI, and NestJS, with clean, high performance, API-first architectures using Redis, Kafka, and Memcached, and proven system design patterns (REST, GraphQL, gRPC, microservices, event-driven systems). I work with databases such as PostgreSQL, MySQL, MongoDB, Supabase, Qdrant, Pinecone,neo4j, and ChromaDB, and develop intelligent AI solutions using LLMs, LangChain, LangGraph, advanced RAG techniques (CRAG, ARAG, Self-Ask RAG, Graph RAG with neo4j), and multi-agent systems with different designs, including networking, hierarchical, supervisor, custom, and supervisor-as-a-tool architectures. I also have strong experience building MCP servers, maximizing their capabilities, and working with no-code automation and AI agent development tools such as n8n, Make.com, and Vapi. I deploy cloud-native systems on AWS, GCP, Azure, Hostinger, and Railway, with solid DevOps practices using Docker, Kubernetes, CI/CD pipelines, and GitHub Actions. If you are building scalable and reliable AI system, I am available.
