Enterprise Banking CRM & Sales Platform

Led the end-to-end architecture and development (backend, frontend, and infrastructure) of an enterprise-scale CRM & sales-force platform for a leading national bank, unifying retail/corporate banking, lead management, pipeline approval, sales productivity, and field-sales tracking into a single platform.

• Architecture & Technical Direction: Defined a Domain-Driven Design + CQRS. Establishing a modular, scalable foundation for parallel team development.
• Backend Development: Built core services - authentication & authorization, lead/pipeline lifecycle, special-rate approval workflows, reporting, bulk import/export - plus an event-driven architecture (Transactional Outbox) for reliable, idempotent cross-domain communication.
• System Integration: Designed integrations with core-banking and external services (SOAP/Loan System, LDAP/HCIS, Google Maps, B-Gate) through an Anti-Corruption Layer that keeps the domain free of external dependencies.
• Frontend Development: Led development application pages (Customer 360, analytics dashboards, pipeline workspace, sales tracking).
• Performance, Security & Reliability: Optimized application performance and enforced banking-grade security (MFA, device fingerprinting, risk-based authentication, audit trail).
• Team Leadership: Set engineering standards, led code reviews, drove technical decisions, and authored architecture documentation as team reference.
