What I'm looking for

I’m looking for roles where I can deliver big data and AI platforms end-to-end—pipelines, orchestration, GenAI/NLP models, and KPI-driven transformation—while coordinating teams to ship measurable improvements.

I deliver big data and data science work that ties directly to KPI accuracy and efficiency, including digitalizing wholesale reconciliations and improving KPI outcomes.

I’ve managed delivery of multiple data projects while coordinating cross-team work to redesign the data & AI ecosystem management, including auditing and transformation planning.

On the engineering side, I’ve built ingestion and processing pipelines with tools like Apache NiFi, Apache Hive, and Apache Airflow, and I’ve orchestrated big data jobs for major performance gains.

For machine learning and GenAI, I’ve worked across TensorFlow, Keras, PyTorch, scikit-learn, and NLP/LLM tooling (including LangChain), from churn/anti-churn and dormancy scoring to Speech-to-Text and Text-to-Speech experiments.
