Applied LLM & RAG

Retrieval-augmented systems and agents grounded in real data — multi-source ingestion, vector search, and cost-aware LLM orchestration.

ML & Model Training

Hands-on model work, not just API calls — parameter-efficient fine-tuning (LoRA/PEFT), computer vision, and measurable results.

Production Full-Stack

Shipped software for real users and clients — rules engines, dashboards, and end-to-end apps with testing and deployment.

Featured work

Projects, written up like an engineer

Four projects — one per focus area — each a short case study covering the problem, the architecture, and the decisions behind it.
