Practical lessons from building ML systems in production — RAG, agents, MLOps, and AI products.
How I Built a Production RAG System with Multi-Query Expansion and Re-Ranking
Most RAG tutorials show the happy path. Here's what I learned building a real system at Emulxion.ai — multi-query expansion, query decomposition, RAG fusion, and intelligent re-ranking that actually improved retrieval accuracy.
Building Human-in-the-Loop Workflows with LangGraph
Fully autonomous AI pipelines sound great until they make an expensive mistake at 2am. Here's how I built WREXT — a content automation platform with approval checkpoints using LangGraph's interrupt mechanism.
90%+ Accuracy Acne Detection with YOLO: What Actually Worked
Training a medical image segmentation model sounds daunting. Here's the practical breakdown of how I built the acne detection system at Emulxion.ai — data, augmentation strategy, YOLO config, and the mistakes I made.
