Project Overview

OnAir is an innovative instant-calling SaaS platform designed to help e-commerce businesses, Shopify stores, and online service providers instantly connect with their customers through real-time voice communication.

Our team partnered directly with the product owner and founder to build the entire platform from scratch — including the web app, mobile app, and Shopify Theme App Extension. From concept validation to system architecture to full-scale development, we acted as the company's technical founding team.

Today, OnAir is a fully deployed, revenue-ready product with seamless communication flows and rich integrations tailored for modern online businesses.

Client Challenges

The founder's vision required solving several complex challenges:

01

Build a real-time calling system with near-zero latency

02

Create a Shopify theme app extension that merchants can install in seconds

03

Develop a responsive, user-friendly Vue.js web dashboard

04

Build a mobile app for managing calls on the go

05

Integrate custom call routing logic

06

Manage caller identities and caller-to-agent workflows

07

Enable call logs, reporting, and analytics

08

Host the platform on a highly reliable, scalable architecture

Since no existing platform matched this vision, the client needed a partner capable of end-to-end product development, technical leadership, and ongoing strategic collaboration.

    Defined the system architecture and communication pipeline

  3. Step 3

    Built the real-time calling logic and signaling framework

  4. Step 4

    Developed the Shopify extension UI & backend integration

  5. Step 5

    Delivered a mobile app for agents and business owners

  6. Step 6

    Deployed a secure, cloud-ready infrastructure

  7. Step 7

    Continued enhancements during production rollout

This collaborative model ensured the product was purpose-built to match the founder's business goals.
