Objectives

• create an online platform for ordering customized heavy duty guardrails; a typical online shopping platform was not a good fit for it because each guardrail may have lots of variants, each variant having a different price and delivery costs;
• solve the pricing problem - come up with an algorithm for calculating the price for each variant of each guardrail;
• keep the running costs low;

Technical-side

• used Kotlin + Spring for the backend;
• used Redis as the non-persistent data store;
• used AWS services for integration: S3 for storage, Lambda + SES for sending e-mails;
• AWS resources deployed using CDK;
• backend is hosted on a DigitalOcean VM;
• the VM on which the app is hosted is configured using Ansible playbooks;
• used React + Material UI for the interface;
• UI is hosted on Netlify.
