Atlas Tax Engine
This project involved the architectural design and development of a highly decoupled tax calculation solution designed to handle regional complexity through a "Headless CMS" approach. Rather than relying on hardcoded logic, the engine utilizes metadata-driven workflows, allowing tax rules, regional exemptions, and calculation parameters to be updated dynamically without redeploying the core service. This architecture ensures the system remains agile in the face of ever-changing global tax regulations.
Atlas Cloud

AI-driven Wholesale Insurance Automation (MVP)
This project aims to revolutionize the wholesale insurance lifecycle by replacing manual touchpoints with a coordinated ecosystem of AI Agentic Avatars. Designed to automate the end-to-end journey, the system deploys specialized AI personas to handle sequential roles—from initial client intake to complex, data-driven underwriting.
By leveraging Python, Claude, and the GSD SDLC framework, we are building an autonomous pipeline that generates instant, accurate quotes without human intervention. Currently in the MVP phase, the focus is on perfecting the hand-off logic between multiple AI agents to validate market viability and streamline operational efficiency.
