Context
This case study reflects systems development work delivered before my senior role, where internal teams depended on browser-based tools for operational processing, management information, and day-to-day support across multiple departments.
The problem
Operational teams were relying on fragmented workflows, inconsistent reporting extracts, and manual handoffs between systems. The business needed reliable internal tooling, clearer KPI visibility, safer access patterns, and faster reporting outputs for decision-making.
My role
I worked as a Systems Developer delivering PHP and jQuery-based internal applications, database-backed workflow improvements, reporting interfaces, and production support. I owned changes end-to-end from schema updates and SQL tuning through to UI behaviour, release coordination, and post-release issue handling.
Approach
I focused on stabilising core workflows first, then reducing operational friction through targeted automation, better data access patterns, and practical reporting UX. Delivery balanced feature work with support, incident response, and controlled rollout processes using existing team governance.
Workflow stabilisation first
I prioritised high-friction internal processes where staff were repeatedly switching tools, manually re-entering data, or waiting on report handoffs. Early iterations focused on dependable PHP-based workflow paths and fast jQuery interactions that reduced repetitive admin effort.
Reporting and KPI visibility
I joined an established systems team and worked alongside other developers to deliver whatever reporting work was most needed at the time. That ranged from writing new BI/MI reports to modifying existing outputs so they included additional data, changed calculations, or updated operational views. I also built fully new visual report screens for week-end and month-end reporting, giving senior stakeholders clearer KPI snapshots without waiting on manual spreadsheet preparation.
Pragmatic legacy-aware delivery
The platform estate combined legacy constraints with active business change. I used incremental delivery through SVN-managed releases, clear change communication, and practical rollback planning to keep risk low while still moving the internal tooling forward.
Intranet plugin for operational visibility
I also created a WordPress plugin for the internal intranet. It was designed as a highly visual, branded entry point using company styling and logo assets, and could be updated dynamically as business information changed. The plugin gave staff immediate access to useful operational links and updates as soon as they landed on the intranet, improving visibility of key information across teams.
