Under MNDA
AWS Cloud Architecture for Internal Data Platform — AWS Cloud Architect & Data Engineer
Developing an internal AWS-based application using a MySQL database as a SSOT for company, contact, project, and inventory data, synchronizing information with various SaaS tools via API. The system must automatically gather data from SaaS APIs (Mozenda, Current RMS, QuickBooks Desktop, RingCentral, Sprout Social), CSV files in Dropbox, email capture, and website forms. It should clean and deduplicate data (ETL with AWS Glue), enrich records via APIs, and display information in a CRM-style dashboard with BI and analytics. Additional logic includes scoring records, automating workflows such as email campaigns and internal notifications, and sending updated data back to SaaS tools. Initial work involves assessing AWS services and estimating usage fees before planning development and implementation.
