Problem

A business needed clients, quotations, invoices, and payment email in one place, and more than one company on the same system.

2. 02 Payments and client email
3. 03 Recurring schedules

2. 02 Job matching
3. 03 Interview status

3. 03 AI-assisted replies

3. 03 Bookings

Gold and silver rates change through the day, and posting each change by hand does not keep up.

I built

A pipeline that fetches the rates, notices a change, builds a poster, and sends it to Telegram, WhatsApp, Facebook, Instagram, and YouTube.

2. 02 Poster
3. 03 Channel delivery

Problem

A new Web API kept starting from the same authentication, roles, data access, and database setup.
