About

Data & AI Engineer | PySpark · Kafka · Databricks · Azure· FastAPI · LangChain Five years building production data systems across fintech, telecom, and GIS domains — specialising in ETL pipelines, real-time streaming, and backend APIs. What sets my background apart: geospatial data engineering is rare. At Hexamap Solutions, I built PySpark ETL pipelines on Databricks, designed 50+ Oracle PL/SQL stored procedures for TNB Malaysia's network backend, and engineered Kafka streaming systems for a Java-based Airtel-IBM fiber topology platform. That combination — spatial, relational, and streaming — gives me breadth across data types most engineers haven't handled. Currently targeting Data Engineer, AI Engineer, and Backend Engineer roles (remote or hybrid preferred). Deepening expertise in Agentic AI systems, vector databases, and LLM-powered data pipelines.
