Agency Order System

The largest subsystem of an influencer-marketing platform: a multi-tenant workspace where agencies, brands, creators and guests run campaign orders from proposal to payout. I was backend lead, built it from scratch, and built its React front end too.

What I built

  1. Payments and invoicing

    Multi-stage pre and post-payment flows, payment holds, a gateway abstraction, creator invoices with PDF generation and payouts, and multi-currency pricing.

  2. Notifications engine

    One BullMQ queue feeding both the activity feed and email, deduplicated and scoped to buyer, creator, admin and guest, plus scheduled posting and reminders.

  3. Real-time chat and order lifecycle

    Live chat and 1:1 messaging on Socket.IO, with multi-participant sessions, unread counts, attachments and guest access, and the state machines behind proposals, revisions, licensing, delivery and late orders.

  4. React front end

    Built with TanStack Query/Router and Panda CSS: agency-order dashboards, calendars, invoice and contract pages, and buyer and guest views.

  5. Auth and security hardening

    Local, Google, Facebook and passkey login with account pre-hijacking defenses and step-up verification. Closed a SQL-injection exposure and moved raw SQL to Prisma.

  6. Admin panel

    Rosters, creator info, order oversight and moderation tooling for the operations team.

AI video editor

A Node.js and TypeScript service that turns plain-language editing requests into finished videos. Each request goes to standard editing tools (blur, flip, subtitle and text removal, overlays) or to generative video models such as Runway, which keeps simple edits off costly model calls.
