As a senior full-stack developer, I was responsible for developing a communication platform (back end + admin front end + Viber bot + Telegram bot) that allows retailers to stay in touch with their customers.

Integrated the communication platform with the client's CRM that allows issuing new loyalty cards to new customers, visualizing customers' loyalty cards, issuing loyalty points, and showing customers' balances – directly from the bot.

The platform provided massive back-end scaling to support short-time massive push notifications announcing marketing activities via the bot to more than 1 million customers. The platform is integrated with other messaging providers to perform as a link in messaging cascade chain.

As a result, the company increased its gross margin by $2 million for the first six months after the module came to production.
