Architecture practice rooted in solutions and design — concrete models, patterns, and hands-on implementation choices — rather than in governance frameworks. Works best in organizations that treat architecture as a delivery function.
Solution and data architect with 24 years in enterprise IT, focused on data platforms and telecom BSS. Works in concrete artifacts — Data Vault 2.0 models, ODCS data contracts, event-driven designs — and stays close enough to implementation to be accountable for what gets built. Equally at home specifying a monitoring framework for senior stakeholders and writing the code that proves it works.

Data and Solution Architect, T-Mobile Croatia (Hrvatski Telekom)
Authoring data contract designs using the Open Data Contract Standard (ODCS v3.1.0), including polymorphic contract patterns that route discriminated payloads to distinct Hub/Satellite pairs while preserving a single logical contract surface for producers.
Designed a three-zone data feed monitoring framework — Infrastructure, Pipeline, and Data Quality — separating signals by failure domain and binding each zone to its own escalation path. Defines the seam between platform-level observability and contract-level data quality assertions.
Established a four-tier severity model (P3/P2/P1/P1+) for data incident management, mapping technical signal severity to business impact and aligning incident routing across producer, consumer, and platform teams.
Specified Cockburn-style use cases for third-party data contract violation escalation, formalising the producer–consumer–operations workflow that governs cross-organisational data sharing.
Designed a Data Vault 2.0 raw-vault foundation for the Group's analytical platform, applying Multi-Active Satellites for slowly-changing reference data, JSON-typed satellites for high-cardinality event payloads, and PIT tables to stabilise downstream analytical queries against an append-only, source-agnostic substrate.
Designed outbound campaign management integration for the Group's unified contact center.
