• Being proactive in communications across teams and platforms to keep a clear picture of the state of things at any given time.
• Ensuring 80-90% test coverage for all new features.

It includes a multi-tenant single-page app for the web and a progressive web app for the mobile with real-time KPIs. The application also includes comparative visualizations across time and venues, employee cost-to-revenue KPIs, alert management for various KPIs, user management, and push notifications to users and groups.
Stayhopper | Micro-booking Hotel Platform
A micro-booking hotel platform where users can book by the hours, days, weeks, and even months. I single-handedly built the Stayhopper suite of apps in about four months. The suite consisted of the following parts:
• A hotel booking website that allows users to search, book, and pay for hotel stays. I used React and Next.js to develop it.
• A RESTful API for all back-end business logic and processing, which I built using Node.js and MongoDB.
• A role-based CMS system for Stayhopper staff to manage properties, users, configuration data, bookings, payments, reports, etc., and for hotel staff to manage properties, bookings, and access their reports and payment information.
• An API to manage pricing, availability of rooms, and support long-term bookings in addition to upgraded micro stay bookings.
• An admin app for super administrators and hotel staff to manage the properties, rooms, pricing, and availability.
• A website for end users to explore, pay for, book hotels, and manage their profile.

Shory - Car Insurance
https://shory.comHelped architect the front end of the Shory Car Insurance App.
Shory is a responsive App that also has native mobile apps.
The tech stack chosen for this project is React and ReactNative, allowing all business logic to be shared between both platforms. Engineers can then build UI components on top of this monorepo for the specific platforms.
This strategy allows minimal code duplication and centralization of business logic, making releasing new features and maintaining existing ones easy. Another added advantage is any React developer can build on top of this stack, given that the core architecture is already in place.
I worked on this project for six months handing over further development to the team I helped hire throughout the project.

MyCRM | App and iPhone App
https://mycrm.com/The myCRM iPhone app allows clients to access the CRM securely to manage properties, add leads, monitor stock levels, and keep track of business performance.

• Allow for development on top of the architecture.
• Distribute the app to the App Store.
