Hello, I am Efstathios Stivaros
A Ruby on Rails Developer from London

ET3 is the form an employer files in response to a claimant's ET1. The service had previously been digitised in PHP. Using the existing service I rewrote the service in RoR.

The service is fully tested (including docker-compose setup for an s3/blob store service locally), observes the GOVUK design principles and uses slim as its templating language.

This is a closed-source project. This application was an in-house, custom-built logistics platform for a business with tens of millions of pounds in revenue.

Work on the project consisted of writing new features, maintaining existing functionality, identifying & removing dead code, patching security vulnerabilities and fixing bugs & providing support.

UK rail staff must regularly inspect stations to ensure high standards. The Planned General Inspection app digitises this process via a mobile app.

Working alongside the mobile team and leading a small backend team, work is mainly focussed on implementing features as per client request and performing general BaU activities.

Upgrading relies on a test suite to highlight regressions, therefore most upgrades are primarily test-writing projects. Projects that have neglected to upgrade tend to have also neglected testing.

Multiple upgrade projects have been conquered with this technique, including Ruby 2.6 -> 2.7 and major Rails upgrades. Other important migrations, such as paperclip/carrierwave -> ActiveStorage and AWS S3 -> Azure Blob Store have also been completed.

This presented an opportunity to work with a project other than Ruby on Rails. Built using Gatsby (which is an SSG for react) and deployed on Netflix, this builds a static blog site from markdown entries.
