The work

I maintained a financial retirement calculator application for John Hancock, built in Angular and TypeScript, used by employees to model retirement scenarios and enroll in their company's retirement program against John Hancock's Signature fund selection. The work focused on keeping a regulated, financial-grade user experience reliable and accurate — covering form validation, masked input, session timeout handling, and a content/configuration model that supported maintenance and demo environments.
