Turning architecture into team capacity and live business results

Meeting growing GenAI demand required the team capacity and resourcing model to take the architecture into production. A structure that allocated resources project by project was limiting capacity.

My contribution

I built the AI Capability team from my architectural vision and made seven hires. I lead this team directly, and the AI CoE squad as chapter lead in a PO-driven matrix structure; 20+ people across the two teams. I moved to a shared resource pool, managed prepaid cloud commitments and led the go-live of 542 IVR. I manage a multimillion-dollar annual AI budget and, as a member of the GenAI Design Authority, report monthly to senior leadership.

Result

The resource pool delivered roughly 30% capacity gain; cloud commitments saved roughly $300–400K. The 542 IVR coordinator handles 100K+ calls a month, with 218K+ calls in roughly the first two months. About 23% of tariff recommendations convert into approved sales leads: 1,000+ leads. Work the teams contributed to includes VHub, TOBi, CX Insight, AQM, GenAI Ops for IT and GuardLine AI.

My leadership directionCombining team building, matrix leadership, capacity planning, budget discipline and production ownership; measuring capacity, cost and customer engagement results separately.

Mar 2025 – Apr 2026Vodafone TürkiyeAI Architect

Designing the agent’s decision space and production foundation

In customer-facing agentic AI, the core design question was how much decision freedom to give the LLM and where deterministic business rules should take over.

My contribution

I designed the 542 IVR architecture to work with different models across on-premises and cloud environments. I built RAG-based access to enterprise knowledge, business rules and security controls into the agent flow. I treated quality evaluation and observability as part of the service-based production architecture.

Result

This laid the architectural and engineering foundation for 542 IVR, which I would later take live as a manager. Business rules, security, evaluation and observability became part of the design.

My leadership directionEvaluating model choice within the full production system; addressing flexibility and control in the same architecture.

Sep 2022 – Mar 2025OpenText (Micro Focus) VerticaLead Solution Architect

Showing the value of architectural decisions through technical and commercial results

Enterprise customers needed different architectural solutions for data loading, query performance and infrastructure costs. I addressed these needs together with the sales teams’ commercial targets.

My contribution

I led solution architecture with account teams covering Türkiye, Central and Eastern Europe, and the UAE. My customer work during the Vertica years included the BTK hybrid lakehouse, the İşbank open banking data warehouse, Sahibinden’s cloud-based disaster recovery/data lake designs, the SunExpress SAP→Azure migration, and data warehouse optimization for an insurance company in Poland.

Result

Together with the account team, we closed roughly $10M in business against a total quota of $6.1M, reaching about 164% quota attainment; 320% in the best year. Customer engagement results: 78% faster data loading at BTK, roughly 45% faster queries at İşbank, 65% lower total cost of ownership in the first year at Sahibinden; and a 60% capacity increase in the data warehouse in Poland. President’s Club and Solution Architect of the Year (FY23–FY24).

My leadership directionEvaluating customer requirements, architectural choices and commercial outcomes in one frame; a solution approach that creates measurable value across different organizations.

Combining solution architecture with regional growth

Growing Vertica in Türkiye, Central and Eastern Europe, and the UAE required sales and partner work to move forward together with solution architecture grounded in customer needs.

My contribution

I took on both business development and solution architecture for the region. Working with account and partner teams, I grew the customer base and the partner ecosystem.

Result

In FY22, I reached 125% of quota; the partner ecosystem grew by 70%. The customer count in Türkiye tripled, and the license revenue share rose from 3% to 10%. I received the Top FY22 Presales/SA International Region recognition.

Mar 2020 – Dec 2020Linktera Information TechnologiesSenior Data Scientist

From a model to a data science team

Customers needed a data science capability that could solve problems as different as credit risk and heavy equipment maintenance.

My contribution

I built and managed a three-person data science team. I worked on risk scoring optimization for a retail loan portfolio and a predictive maintenance model for heavy equipment.

Result

The predictive maintenance model reduced equipment downtime by 40%; the team I built delivered machine learning use cases to customers.

My leadership directionTurning individual technical output into team capability; demonstrating model success through concrete results in maintenance operations.
