👨‍💻 About Me

  • 🎓 B.Tech AI/ML student at Dayananda Sagar College of Engineering
  • 💻 Software Developer Intern at Diarch Group, building production software and AI-driven systems
  • ⚡ Focused on LLM inference & GPU systems — CUDA, Triton, KV caching, batching, and performance optimization
  • 🧠 Exploring LLM post-training with GRPO, RLHF, and parameter-efficient fine-tuning
  • 🤖 Building agentic AI systems using LangGraph, MCP, RAG, and multi-agent architectures
  • 🔬 Interested in understanding AI systems below the abstraction layer, from model architectures and kernels to serving infrastructure

🚀 Featured Projects

⚡ InferenceX — LLM Inference Engine

A custom Qwen2.5 inference and serving engine built from the ground up, focusing on efficient GPU execution and high-throughput serving.

Highlights

  • Implemented custom CUDA/Triton kernels
  • Built KV-cache management and dynamic request batching
  • Designed an inference pipeline for concurrent LLM workloads
  • Achieved 6.34× higher throughput and 2.58× faster processing on an RTX 4050

Python PyTorch CUDA Triton vLLM


🧠 Qwen3-1.7B — GRPO Reasoning

Post-trained Qwen3-1.7B using Group Relative Policy Optimization (GRPO) to improve reasoning efficiency.

Results

  • Reduced average reasoning trace length by 22.2%
  • Reduced average trace length from 579 → 450 tokens
  • Maintained 85% GSM8K accuracy
