Title: Multi-Vendor AdsTech Program Delivery for Indonesia's Largest Telco

Category: Technical Project Management | AI & Data

Overview: Telkomsel, Indonesia's largest telecommunications company, needed to modernize their advertising technology platform with Cookies Sync and SSP API updates. The challenge? Three separate vendors (Insignia, Deloitte, and Eluon) had to deliver interconnected components simultaneously across four parallel workstreams — with zero room for misalignment.

My Role: I served as the central PMO, responsible for unifying all parties toward a single client outcome. This wasn't just about tracking tasks — it was about being the single source of truth in a high-stakes, multi-party environment.

What I Delivered:

Master Schedule Ownership: Created and maintained the integrated program schedule across all vendors, identifying dependencies and potential conflicts before they became blockers.

Documentation Suite: Owned the complete documentation lifecycle — from Software Requirements Specifications (SRS) to Method of Procedure (MOP) to interface specifications. Every party worked from the same version of truth.

Stakeholder Alignment: Facilitated cross-vendor alignment sessions, translating technical constraints into business impact for Telkomsel executives while ensuring engineers had the clarity they needed.

Risk Management: Proactively identified integration risks between vendor deliverables, implementing mitigation plans that kept the program on track.

Outcome: Delivered a unified AdsTech solution on schedule, enabling Telkomsel to enhance their advertising capabilities across their massive subscriber base. The multi-vendor delivery model I established became a template for future programs.
