ING Poland Tech Stack

Large Polish bank modernizing core systems and compliance infrastructure

Banking Katowice 5,001–10,000 employees Founded 1988 Public Company

ING Poland (ING Bank Śląski) is a 5,000+ employee bank headquartered in Katowice, running a polyglot stack anchored in Java/Spring Boot, React, Apache Kafka, and PostgreSQL. The tech adoption and pain-point pattern reveals a bank in active cloud migration: GCP is the only technology actively adopted, while the project list (cloud migration, process automation, credit risk modeling for IRB/IFRS 9) and pain points (legacy application migration, technical debt, compliance automation) show engineering effort concentrated on regulatory readiness and operational efficiency rather than new revenue products.
