A full-stack system that automates participant intake, contracts, deposits and notifications for a law firm's class-action case. Participants sign up on mobile in one pass; the firm manages everything from recruitment to payment confirmation on a single screen.
Class-action work isn't 'who joins' so much as 'who finishes joining.'
Even when people landed on the page, half dropped off at e-signature, and half of what remained dropped off after missing the payment notice. The firm was patching gaps with staff and tracking participants in Excel.
Because the system didn't know where each participant was in the process, the firm was doing the math by hand on who to call next.
Signup → contract → deposit → notification became one flow inside a full-stack system, with a single staff view of who's at which stage.
Participants start on the landing page and finish the Modusign e-signature in the same place. The firm sees participants, deposit status and contract status side by side in the admin, with KakaoTalk alimtalk firing automatically at each step.
Excel export hooks straight into accounting and case-management material. Contract files live in S3, so evidence is quick to recover if a dispute happens later.
Landing and admin in one codebase, with Prisma handling participant, contract and deposit data.
Participants in PostgreSQL, contract files on S3. Tracks evidence through any disputes.
Full Modusign e-signature integration with stage-by-stage KakaoTalk alimtalk firing.
AWS EB deploy that holds steady through traffic swings.
