Analytics strategy & operating model
Define which decisions matter, who owns the metrics, how data products are prioritised and how insight becomes an operating rhythm.
Analytics leadership · transformation · commercial impact
I connect strategy, multidisciplinary project teams of 15–25, trusted metrics and hands-on delivery. The result is not another dashboard estate: it is a clearer operating system for decisions across commercial performance, payments, fraud, customer behaviour and AI-enabled workflows.
Define which decisions matter, who owns the metrics, how data products are prioritised and how insight becomes an operating rhythm.
Lead project teams of 15–25 across analysts, outsourced developers, project managers, technical specialists, suppliers and client-side owners; set priorities, governance, quality standards and accountability.
Turn fragmented reporting into common definitions, commercial narratives, scenario choices and clear actions for senior leadership.
Introduce AI as a controlled analytical multiplier, with human approval, validation, explicit failure modes and verification-first workflows.
Designed and led rollout of a unified campaign-performance data and KPI framework across seven countries. Aligned markets around shared definitions, integrated sources and executive reporting.
Outcome: approximately 20% group-wide uplift in campaign performance.
Consistently led multidisciplinary project teams combining outsourced developers, project managers, analysts, technical specialists and client-side owners. Directed programmes spanning analytics transformation, KPI-system rollout, card-acquiring optimisation, payments-operating-model improvement, and fraud-prevention and fraud-analytics implementation for a large hotel network.
Leadership scope: owned delivery from diagnosis and business case through roadmap, workstreams, supplier coordination, adoption and verified outcome. The wider portfolio included approximately EUR30m invoiced in one year across multiple engagements, including subcontracted work.
Owned forecasting, budgeting and KPI reporting used to steer card-processing operations, working across Payments, Finance, Risk and Operations.
Outcome: approximately 10% processing-cost reduction and correction of a referral-fee classification issue affecting reported margin.
Managed a regional team of 15 using clear KPIs, coaching, commercial negotiation and structured market analysis.
Outcome: consistent target delivery and an early foundation in accountable team leadership.
Public LinkedIn recommendations from former managers and senior colleagues in payments and iGaming.
“Sergejs was in my data/support team at Betfair. He was a joy to work with, providing insightful data with a great narrative. Sergejs is always happy to try new things and work outside of his comfort zone. He would be a great addition to any team.”
“Sergejs and I worked together at Betfair several years ago. Sergejs was always very professional, and it was a pleasure to work with him!”
Map business decisions, stakeholders, metric conflicts, team capacity, data trust and current delivery bottlenecks. Establish where value is leaking and where confidence is weakest.
Agree a small set of priority outcomes, owners and common definitions. Build the delivery roadmap, governance rhythm and visible quality bar with the team.
Deliver one or two high-value decision products end to end, measure adoption and business effect, and use the evidence to scale the operating model.
The leadership proposition is evidence-led: commercial impact, transformation, teams, stakeholder influence and delivery. Tools support that proposition; they do not replace it.
CRepair studies detect-repair-verify loops in long-horizon AI agents through DOI-linked preprints, open benchmark scenarios, public code and cross-model replication.
The research brings a disciplined approach to AI adoption: test the failure modes, require verification, retain human judgement and measure whether recovery actually worked.
