About Me

Hello! I'm Jayash, an engineer with a deep passion for the intersection of backend development and artificial intelligence. My journey in technology has been driven by a desire to not just build applications, but to build intelligent systems that are efficient, scalable, and solve complex problems.

My expertise lies in Python-based backend development, particularly with modern frameworks like FastAPI. I have hands-on experience in the end-to-end lifecycle of AI models—from training, fine-tuning (LoRA/QLoRA), and quantization to deploying them in production environments with a focus on low-latency inference.

I thrive in collaborative environments, working alongside researchers and data scientists to bridge the gap between cutting-edge AI advancements and robust, production-ready systems.

Core Technologies:

  • Python & FastAPI
  • React & Next.js
  • PyTorch & TensorFlow
  • RAG & LLMs
  • GraphQL
  • Docker & Kubernetes
  • SQL & NoSQL
