Hi, I'm Narek Mosisian

Computer Science student at HTWK Leipzig with practical software development experience from IQVIA.

My current focus is backend engineering and GenAI/RAG systems: Python/FastAPI backends, document-based AI assistants, reliable retrieval workflows, evaluation, observability, and deployment.

At IQVIA, I worked on the maintenance and further development of an existing software system in the German healthcare environment. This gave me practical experience with requirements analysis, development testing, technical documentation in Jira, third-level support, and established engineering workflows with GitLab and Jenkins.

My main technical project is llm-reliability-platform, a production-oriented LLMOps/RAG project for document-based AI assistants with source-grounded answers. The project is currently in development and focuses on document upload, chunking, embeddings, vector search, RAG pipelines, an LLM gateway, evaluation workflows, observability, cost/token tracking, and deployment topics.

Another relevant AI project is CCC – Cost Calculation Chatbot, an award-winning university team project based on Knowledge Graphs, RDF/SPARQL, LangChain, and Qanary. The project received the Best Semantic Web Poster Award 2026 at the Leipziger Semantic Web Tag.

I also built Hainstreet, a full-stack web platform project with private domain spaces, authentication, structured membership flows, subscription-oriented product logic, and Docker-oriented deployment infrastructure.

Current focus

  • Backend engineering with Python/FastAPI and TypeScript/Node.js
  • RAG-based AI assistants with source-grounded answers
  • Document processing, chunking, embeddings, and vector search
  • LLM gateways, provider routing, fallback handling, and rate limits
  • Evaluation workflows, citation checks, cost/token tracking, and reliability
  • Docker-based deployment, monitoring, observability, and operational documentation

I am currently interested in working student roles, internships, junior-oriented software engineering roles, and selected project inquiries in backend engineering, GenAI/RAG, and AI-related software systems. You can reach me through the contact page.

Education

B.Sc. Computer Science

HTWK Leipzig - Leipzig University of Applied Sciences

Leipzig, Germany

October 2022 - Present

My Computer Science studies provide the academic foundation for software engineering, programming, databases, web engineering, data-related systems, and applied AI topics. I connect these foundations with practical backend and GenAI/RAG projects.
