The inaugural customer relationship management system for Patungan that revolutionized their client interaction process by transitioning from fragmented spreadsheets to a cohesive, centralized platform. This foundational system introduced critical functionality including contact management, interaction tracking, opportunity pipeline visualization, and basic reporting capabilities tailored to the company's unique workflow requirements. Leveraging Angular's component architecture paired with Firebase's real-time database capabilities, the platform delivered a responsive interface that worked seamlessly across devices while maintaining data consistency. The implementation included comprehensive data migration from legacy systems, custom user permission structures, and an intuitive dashboard that reduced the learning curve for non-technical staff. This pioneering solution established the technical foundation and user experience principles that would guide the evolution of Patungan's customer management ecosystem, setting the stage for the more advanced features implemented in Version 2.
