The Problem

The Finnish telecom operator needed to modernize its complex, legacy-heavy BSS/OSS stack to improve agility and support "Concept-to-Market" (C2M) efficiency. The project required migrating millions of subscribers while ensuring zero downtime and maintaining strict data governance standards in the Finnish market.

The Solution

As the Architecture Lead, I managed a high-performing team of 15 domain solution architects. My primary focus was:

• End-to-End Design: Produced the foundational solution design for CRM, Order Management, and Billing domains.
• Integration Layer: Defined a common integration layer based on WSO2, bridging the gap between front-end channels and complex downstream systems like Amdocs Billing and SAP.
• Process Engineering: Modeled streamlined Lead-to-Cash (L2C) and Trouble-to-Resolve (T2R) workflows using TOGAF and SAFe frameworks.
• Vendor Strategy: Provided critical technical consultation for the selection of enterprise-level security and cloud fulfillment vendors.

Tech Stack

Salesforce, CPQ, Comptel Fulfilment, Azure, WSO2, Amdocs, SAP S/4HANA, SAFe Agile, Oracle.

Impact

• Successfully delivered a blueprint for a unified enterprise architecture that reduced technical debt.
• Established a scalable "Epic-to-Task" structure that improved delivery speed across the agile transformation.
• The solution enabled a more flexible product catalog, allowing the telecom operator to launch new digital services significantly faster than before.
• Increased customer satisfaction by 25%.
