IRIS: briefing distribution & operations backend
Problem
Operational briefings and safety bulletins for Dubai Metro were distributed and acknowledged manually, with no reliable way to track who had seen what, alongside separate paper-based contractor management and revenue-auditing workflows.
What I built
An ASP.NET MVC web system (with a WinForms companion client) that distributes briefings and bulletins as merged PDFs, tracks acknowledgment per employee, and handles contractor management and revenue-auditing workflows on the same backend.
Result
Briefing distribution and acknowledgment tracking moved off paper and email into a single system used across Dubai Metro operations.
LMS with SCORM 1.2 / 2004 support
Problem
The company's learning management system needed to run third-party SCORM training packages (including a corporate induction course) with accurate progress and score tracking — not just "completed / not completed."
What I built
SCORM 1.2 and 2004 support inside an existing ASP.NET MVC LMS: package upload and preview for admins, a learner-side SCORM player, and score/progress tracking backed by SQL Server stored procedures.
Result
Learners can take SCORM-packaged courses inside the LMS with progress and scores tracked accurately, instead of relying on a separate external player.
ERP modules & engineering document control
Problem
A Taguig-based engineering consultancy tracked inventory, tickets, and engineering plan documents through disconnected manual processes, making it hard to know what was current or who had signed off on what.
What I built
ERP modules covering HR and inventory, plus a WinForms document-control client (alongside the ASP.NET MVC web system) for managing engineering plans, tickets, and approvals.
Result
Inventory and document control moved into a single system with a clear approval trail for engineering plans.
No case studies use that technology yet.
