Featured Projects

Unity AI

LLM-powered conversational assistant that lets industrial operators query plant data in natural language. Designed a custom RAG pipeline combining a Neo4j knowledge graph with an InfluxDB time-series store, with grounded citations and data-governance rules that drive confident, source-backed answers and minimize hallucinations.

CV Analyser

AI résumé-parsing platform that extracts text from CVs and returns structured, ATS-ready output with role/skill categorization, plus a chatbot for recruiter Q&A over the parsed corpus. Fine-tuned Llama 3.2, DeepSeek, and Qwen with Unsloth (QLoRA), benchmarked trade-offs across model families, and reached 97% accuracy on a local 3B model — matching cloud-API quality at a fraction of the cost.

Fish Food Pellet Detection

Productionized a YOLOv11-nano computer-vision model that detects and counts fish-food pellets in real-time aquaculture footage, lifting detection accuracy from 40% to 98% and unlocking automated feed-rate optimization for sensor-equipped fish farms.

Sensa Engine

Built Sensa's internal data-orchestration and feature platform — the foundation powering Unity AI, Unity-MLOps, and Pellet Detection. Designed Mage.ai ETL pipelines to ingest sensor and external data into time-series and feature stores, with reusable transforms that serve both real-time anomaly detection and downstream RAG retrieval.
