The tech stack reveals a modernization push: polyglot engineering (Java, Spring, Kubernetes, GraphQL) paired with infrastructure refactoring (containerized logging, infra modernization) and enterprise tooling consolidation (Salesforce CoE, Jenkins CI/CD). Hiring velocity is accelerating with engineering roles leading the charge, suggesting capacity-building for the overseas EPC project pipeline.
