Field-service CRM — heynota.app

Nota CRM

Nota is the product I ship for field teams: live job map, mobile technician hub and billing — marketed at heynota.app, app at app.heynota.app.

Nota CRM is the commercial product behind my field-service work. The marketing site (heynota.app) explains the offer; the application (app.heynota.app) is where teams run jobs day to day. I own product, engineering and UX end to end.

01 / Problem

The product problem

Companies that send technicians to customers still run on Excel, WhatsApp and scattered invoices — with no shared map, status or mobile workflow.

02 / Approach

How I built it

I designed Nota around three pillars: a live intervention map for the office, a mobile hub for technicians in the field, and billing tied to closed jobs — one stack, one source of truth.

Full-stack CRM for on-site interventions: dispatch on a map, client files, technician PWA with offline sync, invoicing and role-aware admin. Built with Next.js, TypeScript, Firebase, Mapbox and Stripe.

03 / Outcome

What you can verify

A public product site at heynota.app linking to the live app, with concrete sections for map, mobile and invoicing — and a portfolio case study that connects my name to the shipped product.

  • Live job map for dispatch and follow-up
  • Technician mobile hub (PWA, offline-aware)
  • Billing linked to completed interventions
  • Marketing + app surfaces (heynota.app / app.heynota.app)
  • Built end-to-end: product, code, UX
