Enterprise Custom CRM System
High-performance APIs for client tracking, pipeline, and transactions
Overview
Developed the backend API layer for a custom enterprise CRM system, covering client relationship management, sales pipeline tracking, deal forecasting, and transaction processing for the corporate sales team.
Off-the-shelf CRM solutions didn't map to the company's complex multi-entity sales structure and required expensive customization. The sales team was using a mix of Excel and email to track a 200+ client pipeline.
Built a modular Laravel + NestJS hybrid API with a domain-driven design, covering client accounts, contact management, opportunity stages, activity logging, and automated forecasting reports. Integrated with the internal ERP for seamless deal-to-invoice workflows.
Sales team pipeline visibility improved dramatically. Sales cycle tracking time reduced by 3 hours/week per salesperson. Forecasting accuracy improved to 87% from previously unmeasured gut estimates.
