Chivy Fullstack Platform
The Chivy's founding team already had an MVP with a complete outdated stack:
1.5 years outdated ReactNative app with tons of bug reports
No redundancy/No scaling - one server to run the one instance of the API in both env: staging+prod
Poor data model
Everything needs to be rebuild from the ground-up as the support and update of the current was more expensive than a complete rewrite from scratch.
True honest timeline:
Contract signature including documentation: 07/29/2024
Beginning of development: 07/30/2024
A full feature shipping into production: 11/01/2025
3 Months to completely rewrite a Tinder/Bumble like application including new back-end & new infrastructure.

A bit of documentation
Just enough to make sure I understood the needs and the core business logic.
Also so we can put it in the contract.
❓Functional specifications
How is it supposed to behave?

Scope
Budget
Timeline
Development phase
My own secret spices.
Infrastructure As Code (IAC)
We chose Terraform to setup a full-size infrastructure at AWS including:
Elastic Kubernetes Service (EKS)
Elastic Container Registries (ECR)
Elastic Load Balancer (NLB)
Elastic Compute Cloud (EC2)
Relational Database Service (RDS)
Guard Duty
CloudWatch & CloudTrail with aggregated logs from the cluster & many alerts on the instances
... more than 100 resources at AWS
Back-end development
For us a back-end is the code base of an API or a Worker, either exposing routes through a restful API or reacting asynchronously to messages from a queue. It's made of:
Typescript 5.9, NodeJS 22
MongoDB 6
Express 5
Docker Node 22-alpine
Typescript
Front-end development: iOS
To keep up with the latest iOS version & tools, we opted-in for a complete rewrite of the existing application with Swift UI on iOS 17.
