Design technical architecture for banking platforms (core banking, loan management, digital banking, etc.). Define high-level solution architecture for new applications or services. Ensure systems are secure, scalable, and comply with OJK/BI regulations. Collaborate with cross-functional teams (e.g., business analysts, developers, DevOps, security). Perform system integration design with third-party services (payment gateways, API, SWIFT, etc.). Document architectural decisions, system flows, and infrastructure diagrams. Support digital transformation projects and migration to cloud or hybrid environments. Evaluate new technologies and propose upgrades or architecture enhancements. Troubleshoot architectural-level system issues and support performance tuning. Ensure disaster recovery, backup, and failover plans are in place and tested.
