The platform
A major pharmaceutical company needed a central place for employees to access research resources, training materials, and internal documentation. The platform had a search function that queried a curated selection of their most-used resources and displayed results directly on site, so people didn't have to jump between tools.
Front office and back office
The front office was the employee-facing side: browsing resources, accessing training, checking the calendar. The back office was where administrators managed users, groups, research databases, documentation, and an internal file system. There was also a training event module: create an event, assign it to user groups, and it shows up in their calendar automatically.
SSO
I implemented Single Sign-On so employees could access the platform without managing separate credentials. For a corporate intranet, that kind of seamless access matters. One less barrier between people and the tools they need.
Going responsive
The site was originally desktop-only. The assumption was that employees would use it from their workstations. That assumption turned out to be wrong pretty quickly, so we went through a full redesign to make it work on any device.
Technical choices
I chose CodeIgniter as the framework because it's lightweight and easy to get into compared to heavier alternatives. For this kind of project, that pragmatism paid off. I also set up the servers on AWS EC2 and handled the full-stack development with a high level of autonomy: direct contact with the client, framework choice, architecture decisions, the works.
