What I'm looking for

I'm looking to translate business challenges into scalable AI and data solutions, building and optimizing cloud-based ML models, production data pipelines, Feature Stores, and MLOps workflows.

I've built fraud detection and document intelligence systems for banking clients at Intelygenz, including an XGBoost model that improved feature retrieval latency by 30% within an MLOps workflow.

I design production-grade LLM workflows using hexagonal architecture, Saga orchestration, and NATS to automate document classification and field extraction at scale. Previously at Enthec Solutions, I optimized Elasticsearch indexing, shard allocation, and query execution, and built AI-enabled web scraping with BERT-based webpage classification.

I also built a supervised ML experimentation web application at ATK Language to benchmark models and identify the best-performing algorithm. My work spans Python, MLflow, Kafka, Snowflake, Kubernetes, AWS, Azure, and observability tooling.
