Ali Akbar G.
Java Backend & ETL Engineer | GIS & Data Transformation Specialist
Software Engineer with hands‑on experience in Java/Kotlin and microservices combined with strong GIS and ETL skills. I help businesses automate data workflows, build scalable APIs, and transform large datasets into meaningful insights. • Backend & API Development Building internal tools or integrations? I develop REST API endpoints, scalable services, and database routines to enable seamless data input, processing, and retrieval. • Bulk Data Transformation & Automation (ETL) Need to migrate, clean up, or synchronize large datasets? I design automated pipelines to extract, transform, and load data so your systems stay accurate and up-to-date with minimal manual effort. • GIS Mapping & Visualization If your project involves geographic data like mapping addresses, routes, or zones I leverage GIS tools to visualize data clearly, helping users and stakeholders make sense of spatial information.
