What is Customerly?

Customerly is the first-in-class AI customer service platform designed to help businesses automate customer support, enhance engagement, and drive retention. Powered by advanced AI Agents, Customerly seamlessly switches from AI Assistant to Mission Mode, resolving customer inquiries instantly while intelligently escalating complex cases to human agents.

Unlike traditional chatbots, Customerly is an AI-first solution that enables businesses to create fully customizable workflows, reducing response times and improving customer satisfaction. It also includes NPS & CSAT surveys, email marketing automation, and customer success tools, making it a comprehensive solution for SaaS companies looking to scale support operations efficiently.

Web application

The web app is the main project we manage in the team. It's the app Customerly's clients use to manage their customers' conversations, creating Chatflows, managing their Help Center and more.

Chatflows

It's based on React, built on Vite and Typescript. We used different technologies like WebSockets and many more to give the best experience to the users.

Messenger

The Messenger is one of the main features of Customerly. It is the main interface for the customers to interact with the company.
It's been accessed more than 100M times every month. It's based on React and I developed the last version from scratch in 2024.

Help Center

The Help Center is a feature that allows customers to search for answers to their questions. It's built on NextJS with ISR to give the best performance. As shown in the image below, when we released it (in 2023) we were performing better than our competitors on GTMetrix.

Mobile App

The mobile app is built on React Native and Expo. It's a simple app that allows customers to interact with their clients answering conversations and more. I didn't develop the app, but I reviewed the code.

AI

The AI is the main feature of Customerly. The customers can create Chatflows to automate their conversations with their clients. We manage it with multiple LLMs in our backend.

Chatflows

Our customers can also gather conversations data in automatic way using AI and use it to do different actions like for example calling custom APIs.

Backend

The backend is built on PHP and most of APIs are managed with Symfony. We also use Redis to cache data and for internal purposes. I don't work usually with the backend, but sometimes I do some changes to the code.

Infrastructure

The infrastructure is managed with Terraform, hosted mostly on AWS. I usually take care of it when we need to deploy something new or when we need to migrate to a new service.

What I do

I work on many parts of the project. Mainly on the frontend and infrastructure. I also do some changes to the backend and AI code when needed. I'm also a partner of the company.
