Utazzo Holidays: CRM and Platform Rebuild on AWS
View completed workutazzoholidays.com
Delivered with my team at Codevibe Technology.
The client
Utazzo Holidays sells curated holidays across India and abroad: 44+ destinations, more than 100,000 travellers and 14+ years in business.
The problem
The platform running the business was a monolith built on Angular, .NET and Microsoft Access, hosted on Windows servers.
The web app, CRM and admin were slow and hard to load on the low-end devices travellers use
Lead management ran through the CRM, but entirely by hand, with a manual hand-off from pre-sales to sales
One codebase where every change risked the whole system, and no cloud elasticity
What we did, in five phases
Discovery and architecture: mapped the monolith, the sales workflow and the data trapped in MS Access, then designed microservices and a clean PostgreSQL data model.
Rebuilding the web app, CRM and admin: a Next.js customer web app and a React CRM and admin, built to hold up on low-end devices.
Microservices and cloud: split the monolith into independently deployable NestJS services in containers (ECR, EC2), backed by RDS PostgreSQL and Redis, and moved the platform off Windows onto AWS.
AI across the pipeline: lead routing and prioritisation, and the pre-sales to sales hand-off automated instead of done by hand.
Migration and handover of the live business onto the new platform.
The public website rebuild is a separate case study on my profile.
Stack: Next.js, React, NestJS, PostgreSQL, Redis, AWS (EC2, ECR, RDS).
