Hi 👋, I am Ajit

Senior AI Engineer | Generative AI | RAG | Document AI | Backend Engineering | MLOps

  • 👨‍💻 Senior AI Engineer with 6+ years of experience across Machine Learning, Generative AI, Computer Vision, and Backend Engineering.
  • 🤖 Building production AI systems using LLMs, RAG, embeddings, vector search, prompt engineering, OCR, document classification, and information extraction.
  • ⚙️ Experienced in developing production services with Python, FastAPI, PostgreSQL, pgvector, MongoDB, Redis, Docker, Kubernetes, and Helm.
  • 🚀 Hands-on across the full AI lifecycle: experimentation, evaluation, APIs, CI/CD, deployment, observability, and performance optimization.
  • 🧠 Currently exploring Agentic AI, advanced RAG architectures, AI evaluation, guardrails, and tool-based LLM workflows.
  • 🎓 MSc in Artificial Intelligence / Informatics from RPTU Kaiserslautern, with a thesis at DFKI on 3D perception and time-to-collision estimation.
  • 🏢 Professional experience across Elevait, Must Analytics, TeamViewer R&D, PwC, and other engineering environments.
  • 🛠️ Regularly using Claude Code and Cursor for AI-assisted software development while maintaining engineering review, testing, and production-quality standards.
