Introwise

Founder, CTO and the primary developer of an all-in-one business platform for coaches and consultants. The platform combines scheduling, no-code booking page builder, built-in video calls, payments, lightweight CRM, automation workflows and integrations, and much more.

The product is a web application written using React in TypeScript, with serverless Firebase backend.

Frontend is a custom webpack-bundled React app, styled with vanilla-extract TypeScript-based static CSS generator. SSR-enabled using a custom system that utilizes Firebase Hosting CDN and Cloud Functions for effective rendering with fast deployments.

Backend is fully serverless run on Firebase. Cloud Functions are used both for event-based background-triggered features, and for user-initiated RPC-like sync features. PubSub and Cloud Tasks are used for orchestrating multiple functions. Cloud Firestore is used as a database, enabling most of the UI with real-time updates.
