Independent analytics consulting · payments · fraud · BI
I help organisations turn fragmented commercial, payment and behavioural data into trusted decisions, controlled risk and measurable outcomes. Engagements are senior, hands-on and tightly scoped — most start with one high-value question, not a year-long programme.
Low-risk to start
Most work begins with a tightly scoped, senior engagement — useful on its own, and a way to check fit before anything larger.
Fixed scope or fractional
Fixed-scope diagnostics and sprints for a specific question; or a recurring fractional day or two a week for ongoing analytics leadership.
Remote · confidential
Remote or hybrid, UK-based. Client work is handled under NDA; public references use synthetic data only.
For payments & risk teams
Problem it solves. Unclear where fraud, bonus abuse, processing cost or customer friction is really hurting the business — and which lever to pull first.
What's included. A structured review of transactions, payment flows, fraud/abuse signals, processing costs and friction points, against the decisions they drive.
What you get. A quantified opportunity-and-risk map, prioritised, with a concrete action plan you can act on with or without me.
For any commercial team with one urgent question
Problem it solves. One expensive, specific question: where margin is leaking, why conversion dropped, which cohorts abuse bonuses, why KPIs disagree, or where payment rules add needless friction.
What's included. A focused, senior investigation over 5–10 working days: data, analysis and a clear answer — not a staffing exercise.
What you get. An evidence pack, findings and specific recommendations. A low-risk, tightly scoped way to get a useful result — and check fit before larger work.
For leaders drowning in dashboards
Problem it solves. Fragmented reporting, conflicting metric definitions and a sprawling dashboard estate that leadership no longer trusts.
What's included. Diagnosis of the current reporting and definitions, then a common metric framework and an executive reporting model that people agree on.
What you get. One measurement language, a leadership-ready reporting model, and a realistic implementation roadmap.
For teams not yet ready for a full Head of Analytics
Problem it solves. You need senior analytics direction — priorities, quality, delivery — but not yet a full-time leadership hire.
What's included. One to two days a week: setting priorities, steering analysts and suppliers, holding a quality bar, translating for leadership and getting analytics adopted.
What you get. An operating rhythm for decisions, a rising quality bar, and analytics that actually reaches the business.
AI-enabled tools are used where they improve speed, coverage or verification, with human review throughout. The product is a solved commercial problem, not an abstract AI programme.
Public reference builds using synthetic data — the implementation is openly inspectable, so you can judge the work before we speak.
Payment risk · public notebook
Fraud scores translated into approve, review and decline decisions, with validation, customer-friction and manual-review trade-offs.
Agentic analytics · reference build
Governed revenue investigations with PostgreSQL/dbt evidence, typed tool boundaries, human approval and outcome verification.
Analytical model · interactive
Task-exposure, labour-market signals and the full, loaded economics of automation — a working, source-backed analytical product.
Public LinkedIn recommendations from people I worked with in payments and iGaming. These are professional recommendations from former colleagues and managers — not client testimonials.
“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.”
“Sergejs and I worked together at Betfair several years ago. Sergejs was always very professional, and it was a pleasure to work with him!”
A few lines on the problem, the decision it affects and a rough timeframe. No polished brief needed.
A short call to agree the question, the shape of the engagement and what "done" looks like.
You get a useful result quickly, then decide whether to go further. Small engagements often lead to larger ones.
Have a specific problem in mind? Send a few lines — the decision it affects and a rough timeframe — and I'll reply with whether and how I can help.
