Nadezhda Mihaylova enhanced CRM functionality in the ErpNetDocs/tech and ErpNetDocs/model repositories by delivering three features focused on automation, data validation, and documentation. She automated the offer-to-customer workflow, allowing offers to be created without an existing customer and linking them automatically upon approval, streamlining sales processes. In ErpNetDocs/model, she implemented a business rule to validate lead locations against enterprise company records, improving data consistency. Nadezhda also updated CRM documentation for version 26.2, restructuring Markdown and YAML files to improve navigation and onboarding. Her work demonstrated depth in CRM systems, business rule development, and technical writing within a one-month period.
