Case Study | Unseen Engine

the challenge

Event Espresso was scaling a multi-city mobile coffee catering business on paper notes, voice memos, and scattered tools. Follow-ups dropped. Inventory lived in people’s heads. They needed one system from first inquiry through procurement, execution, and returns — with a path to franchise later.

Our Solution

We designed and built BrewTrack, an end-to-end operations platform: public magic-link event requests, multi-location inventory, PO lifecycle with a tokenized supplier portal, post-event returns, and RBAC for Admin, Manager, Assistant Manager, and Client.

The product stays in the team’s hands. We ship against live ops feedback — calendar visibility, survey reminders that stay human-in-the-loop, and booking-flow fixes — then demo and deploy with Casey, Soph, and Lee.

The process

Discovery

1-week intensive requirements gathering and compliance review

Design

Wireframes and interactive prototype in Figma within 10 days

Development

4 agile sprints with weekly demos and feedback loops

Launch

Deployed to AWS with full CI/CD pipeline and monitoring

Technology Used

Django 5.1, DRF, PostgreSQL, Redis, Celery, Next.js 16, React 19, TypeScript, Tailwind, shadcn/ui, OpenAI

The results

Live since May 2026 at app.wecatercoffee.com, processing real event bookings across 13+ hub cities.
Replaced a manual, error-prone workflow with one integrated ops system: requests, inventory, POs, returns, and role-based admin.
Shipped calendar UX, post-event survey reminders, quotes with line items and payments, fractional inventory, and closest-hub assignment in weeks — not months.

We were scaling coffee catering on paper notes, voice memos, and dropped follow-ups. BrewTrack is the system now — event requests, inventory, and procurement in one place. That is the difference between guessing and running the business.
