Über Ranjeet

Senior Backend Engineer & AI Automation Consultant with 14+ years of experience building scalable distributed systems and integrating AI into production workflows. Based in Munich, Germany.


I help companies automate manual processes using AI — from LLM-powered customer support agents to intelligent data pipelines that replace hours of manual work. I combine deep backend engineering expertise (Golang, Kubernetes, AWS) with hands-on AI/ML integration to deliver automation solutions that actually work at scale.


What I offer:

— AI Automation Consulting: LLM integration, RAG pipelines, AI agents, workflow automation

— Backend Engineering: Golang microservices, event-driven architecture, high-throughput APIs

— Infrastructure & DevOps: Kubernetes, Terraform, AWS/GCP, CI/CD pipelines


Key highlights:

— Built Golang voucher management service handling 10M+ EUR at Flix/Gelato on AWS EKS

— Developed AI-powered customer query resolution agent using LLM integration and RAG pipelines

— Built an AI job application tool that automates 90% of form-filling — saving hundreds of hours

— Migrated legacy monolith to Kafka-based event-driven microservices at Sixt

— Implemented 3D Secure payment flows and high-volume APIs across mobility platforms


Tech stack: Golang, Python, Kubernetes, Docker, AWS (EKS, EC2, RDS, DynamoDB), Terraform, Kafka, PostgreSQL, LangChain, OpenAI API, React, TypeScript


Available for long-term freelance contracts, project-based work, and AI automation consulting engagements. Remote or hybrid from Munich.
