Fine-Tuning Open-Weights Models with QLoRA & Unsloth
A practical hands-on guide to parameter-efficient fine-tuning (PEFT): 4-bit quantization, Low-Rank Adaptation (LoRA), Memory footprint management, and 2x faster training with Unsloth.
Read articleBuilding RAG pipelines, autonomous multi-agent systems, and deep-learning architectures from scratch — no black boxes. 20+ production-grade projects shipped across LLMs, computer vision, and reinforcement learning.
The future of AI isn't about replacing humans — it's about amplifying human intelligence. Machine learning teaches patterns, deep learning reveals hidden insights, and reinforcement learning shows us how to adapt.
Together, they're the building blocks of tomorrow's intelligent world.

I'm an AI/ML Engineer specializing in Large Language Models, Agentic Architectures, Deep Learning, and Production ML Pipelines. I build scalable RAG architectures, fine-tune open-weights models (Llama 3, Qwen, Mistral), and construct autonomous AI agents that plan, critique, and execute tool calls with high reliability.
From low-level model optimization to real-time evaluation harnesses and production deployment, I focus on turning complex machine learning research into resilient, real-world software applications.
