Web Development Projects & Clients

Throughout my career, I have had the opportunity to work on a diverse range of web development projects. Here are a few examples of my more recent work.

Q4 Metrics

Q4 Metrics offers a distinctive set of survey tools designed to assist with analysing key aspects of people management, stakeholder engagement, and their impact on organisational performance. I contributed to developing Q4 Metrics' survey development tool and back-end programs, which facilitate data analysis and representation.

University of Glasgow

The University of Glasgow's Institute of Infection, Immunity & Inflammation brings together leading researchers in viral and pathology studies and provides access to high-end research equipment. I developed a custom system using PHP and Javascript to meet their need for an online booking system. The system includes invoicing, accommodates group/user prices, and allows for booking both rooms and equipment.

  • MySQL

CCR3 Performance Management

CCR3 specialises in providing its clients with a fully integrated performance management solution, enabling them to measure, manage, and develop various HR aspects. As the Lead Web Developer at CCR3, I created a sophisticated web application capable of constructing, administering, and executing multiple Questionnaire Tools while managing reseller permissions, usage, and billing automation. To meet the specified requirements, I managed the project and oversaw the development of a completely new version of the software.

EmuBands

As the lead full-stack developer for EmuBands, I created a robust user platform for their digital music distribution service. EmuBands offers a powerful and user-friendly tool for getting music onto top digital services like iTunes and Spotify.
Recently, I oversaw and participated in the migration process from the previous Yii-based platform to a new platform based on PHP Symfony. This upgrade resulted in significant improvements to the user interface, new features, and enhanced performance.

  • Symfony
  • MySQL
  • Stimulus

Yes Scotland

Yes Scotland was the organisation that represented the parties campaigning for a Yes vote in the 2014 Scottish independence referendum. As part of the campaign, I developed a Progressive Web App (PWA) for smartphone devices designed explicitly for door-to-door canvassing.
The PWA app allowed for location and survey data collection by the campaign volunteers. React and Angular were not yet available, so we developed the app from scratch using plain Javascript to ensure it could function on smartphones without requiring a download.

  • Javascript
  • PWA
  • CSS and Bootstrap

Dubai Police

From 2018 to 2022, Dubai Police participated in Dubai's Career Expo, utilising an HR assessment tool to assess potential job candidates. As the lead developer, I used PHP, Yii, MySQL, and algorithms to develop a cloud-based HR assessment tool for Dubai Police to evaluate potential candidates.
The tool features a sophisticated web application capable of constructing and administering multiple questionnaire tools and providing data analysis, representation, and sample selection.

Find Lab Tests UK

As the CTO and Lead Full-stack Web Developer, I played a significant role in designing and building FindLabTest, the UK's largest comparison directory for health and lab tests. The platform was developed with geosearch and booking functionality using PHP, Symfony, and Javascript.
Stimulus was used for the front-end, while Turbo was leveraged to improve the user experience. To help manage the vast amounts of data involved in running such a platform, I created a set of Console Commands to scrape and sort through the information.

  • PostgreSQL

  • Mapbox

COVID-19 Vaccine Queue Calculator

Amid the Covid-19 pandemic, the COVID-19 Vaccine Queue Calculator assisted individuals in Italy in obtaining an approximate position in the queue for receiving the Covid vaccine. The calculator employed the Italian government's official priority list and vaccination rate to estimate the number of people ahead in the queue and the waiting time.
As a developer, I contributed to developing this tool by leveraging Symfony, PHP, and API calls to data sources to derive an accurate estimate using advanced mathematical formulas and big data.

  • Symfony
  • PostgreSQL

Seed & Eat

Seed & Eat is a digital platform similar to Airbnb, but for gardens, allowing users to offer or rent short-term outdoor spaces. The platform is designed as an online marketplace with advanced search functionality, location geocoding, and booking system.
The application is built using PHP and Symfony to power the back-end, and React for the front-end, providing users with an interactive and user-friendly interface.

Rightsbridge

Rightsbridge provides music makers and industry professionals a platform to manage, monitor, and monetise their music copyrights. Their Dashboard Application allows users to submit registrations, view their catalogue, collect earnings, and access data analytics tools to gain insights into how their music is exploited.
