Bluecrest WellnessProfessional project
Bluecrest Wellness is a fully integrated Strapi and Next.js Mini-CMS, built to replace an outdated WordPress site for Bluecrest. I designed and built a flexible system where marketers can customize pages, manage content, themes, and layouts, and control branding in real time. The result? Faster load times, stronger SEO, and a seamless workflow for non-technical staff
LBH MarketProfessional project
A single-stop platform for small businesses to showcase and sell goods without the overhead of a standalone e-commerce store. LBH Market combines a user-friendly interface (React/Next.js) with secure back-end and payment integrations (Node, Express) for effortless product management and sales processing.
VybitePersonal project
An AI-integrated Event recommendation and ticketing application. It is a mobile and Web application, where users can ger recommended various movies, concerts, shows, etc. It also provides a seamless way to purchase and use tickets.

E-council surveyAcademic project
A production-ready react and firebase PWA and RESTful service for polling residents of a city council. The project implements features like QR scanning, animated UI components (to give it an app-like feel), charts, live data updates, secure API, and more. It was developed as an academic project.
Montego Pool CarsProfessional project
A web application developed for Montego Upstream Services to help fleet managers, drivers and staff, book, organize track and document trips taken in the office. The app is divided into three sub-systems (one for each entity).
Kint UIPersonal project
A react UI library built 100% from scratch with JSX and CSS only. The library contains most of the common UI elements used in web app development like buttons, layouts, text, loader, cards, modals, etc. The library is currently used in the LBH Market website and this portfolio site.
(The project is currently unreleased to the public because documentation isn't yet available.)
RUTESAcademic project
As part of my MSc. research project, I developed a system called RUTES (Remote Usability Testing and User evaluation Suite) for conducting remote evaluations and tests on web applications. RUTES comprises two subsystems: an admin panel for creating and modifying test parameters, and a JavaScript library that is embedded in the target project and provides an interface for testers to interact with it.
With RUTES, remote testing of web applications becomes more efficient and streamlined, as testers can access the application from anywhere with an internet connection, and administrators can customize test parameters to suit their needs.
The system was awarded the Best Computer Science Technical Project in 2022,
Websites and Landing Pages project
I have also built some static websites and landing pages for personal and company profiles. Some of them are listed below.

I am a Frontend & Full Stack Developer with 5+ years of experience creating high-performance, scalable web applications. I’ve worked on projects in fintech, health-tech, and e-commerce, where I learned the value of clean code, sound architecture, and user-friendly designs.
Currently, I’m a Frontend Developer at iwoca, though my role often extends to Python tasks for full-stack solutions. I’ve led optimizations like moving an iwoca application from Next.js to Vite, cutting both bundle size and build times, and moving multiple Bluecrest projects into an NX monorepo, boosting shared-module efficiency.
My academic background includes a BSc. in Computer Science (Babcock University) and an MSc. in Advanced Software Engineering (University of Leicester). During my studies, I built everything from remote usability testing suites to e-commerce platforms, honing my skills in agile methods and cross-functional teamwork. The project was awarded the best technical project prize in 2022.
Outside work, I invest in learning and development, exploring new frameworks and maintaining personal projects like WishFlo to stay adaptable and innovative. Over time, I hope to lead teams and mentor developers, creating an environment where collaboration and continuous growth thrive.
Whether I’m refining React components, designing REST/GraphQL APIs, or setting up CI/CD pipelines, I aim to deliver maintainable, user-focused solutions.
