Nick Shevelov developed an investor filtering and profile validation feature for the memser-spaceport/pln-directory-portal repository, focusing on enhancing data integrity and segmentation accuracy. He implemented new validation rules in TypeScript to ensure FUND investors are correctly linked to fund teams and ANGEL investors have all investment-related fields populated. The work included backend and API development, introducing the isInvestViaFund field to the investor profile data model to support more precise categorization and analytics. By improving the underlying data structure and validation logic, Nick reduced manual validation effort and strengthened the portal’s readiness for downstream analytics and reporting without addressing bug fixes.
