Led full-stack development and frontend architecture for multi-module web applications; implemented Flux-based client-side logic, integrated Azure services (Key Vault, Storage, B2C) and CI/CD pipelines; improved UI consistency and development speed across projects; collaborated with product and design teams to optimize performance metrics and user engagement.

Adopted DevOps practices to streamline development processes and mentored developers in the adoption of web components on mobile-first websites with WordPress CMS integration and mixed architectural patterns, ensuring reusability, exceptional code quality and system efficiency. Partnered with non-technical stakeholders (product owner and project manager) and clarified technical solutions to define ticket scopes and timelines for Kanban boards, facilitating effective prioritisation and prompt delivery by 28%. Introduced the use of W3C accessibility standards and facilitated web performance testing on web applications (including single-page applications & PWA), and websites, and applied code optimisation techniques, such as compression, code splitting, and lazy loading, on web applications, single-page applications, and websites, resulting in a significant improvement in one of the projects' LightHouse audit scores from 52% to 98%. Played a key role in developing a scalable e-commerce progressive web application (PWA) and offline functionalities, and an IT administrative dashboard for enhanced user engagement and effectively managing commercial activities for over 100 businesses.

Migrated legacy code, with 250,000+ users and 4,000+ businesses, following the Component-based architecture, and developed intuitive user interfaces to improve agreements' reviews and amendments using a WYSIWYG tool, leading to a 25% improvement in overall data accuracy. Explained technical solutions to non-technical stakeholders and transformed feedback and insights into actionable product enhancements, leading to a 15% increase in positive user reviews and a 10% reduction in user-reported bugs during code migration. Collaborated with a dedicated, cross-functional scrum team, from QA to product managers and Scrum master, to implement a rapid, responsive and semantic web design and intuitive user flow for the audit system and acquisition tracker on multiple devices and operating systems. Performed debugging to identify and fix the erroneous progression in the acquisition tracker.
