About Me

About Me

Hi, I’m Ankit Kumar, an AI/ML Engineer and Backend Developer passionate about bridging the gap between complex data science research and production-grade software engineering.

Over my career and freelance consulting, I have designed and deployed multiple conversational AI systems and LLM/RAG architectures, including building and fine-tuning transformer models from scratch. During my time at the Indian Space Research Organisation (ISRO), I designed Reinforcement Learning simulators for Lunar landing trajectories and engineered high-throughput telemetry pipelines.

Whether it’s optimizing physical solvers, training 10+ distinct machine learning architectures, or scaling backend services for thousands of active users, I love building performant, scalable, and intelligent systems.

Here are a few technologies I've been working with recently:
  • Python & SQL
  • PyTorch & TensorFlow
  • Generative AI & RAG
  • Reinforcement Learning
  • Django & FastAPI
  • Docker & CI/CD
