Apex Financial Architecture

Finance & Systems Consulting

Senior finance expertise, delivered at the speed your project actually needs.

I build the financial models, lead the system implementations and fix the finance processes that sit behind them — working directly with you, not through a layer of junior consultants.

Services

Four things I am genuinely good at.

Most engagements start with one of these and grow from there. Scope can be a single deliverable or an ongoing part-time commitment.

Financial modelling & valuation

Models that stand up to scrutiny from a board, a lender or a due diligence team.

  • Three-statement, budgeting and forecasting models
  • Group consolidation models
  • Valuation and M&A modelling
  • Cash flow analysis and scenario planning
  • Review and rebuild of inherited models

ERP & finance systems

The finance side of a system programme — requirements, design, data and the people using it.

  • Dynamics 365 and NetSuite implementations
  • Chart of accounts and reporting structure design
  • Data migration and reconciliation
  • New-entity and new-market rollouts
  • Systems architecture for finance

Finance transformation

Making the monthly cycle faster, cheaper and less dependent on one person's spreadsheet.

  • Process automation and month-end acceleration
  • Financial performance improvement
  • Management reporting redesign
  • Controls and reconciliation frameworks

Interim project leadership

A senior pair of hands to own a finance or systems programme end to end.

  • Project and programme management
  • Business analysis and requirements
  • Vendor and stakeholder management
  • Fractional finance lead for smaller teams

How I work

Fewer people, less time, same standard.

01

You get the senior person

The person you speak to on the first call is the person who does the work. No pyramid, no handover to a team you have not met, no learning on your budget.

02

AI-accelerated, human-verified

I use AI heavily for model construction, analysis and documentation, which compresses timelines dramatically. Every output is reviewed and sense-checked by me before it reaches you. You are buying the judgement, not the keystrokes.

03

Remote and asynchronous by default

I work with clients across eight time zones. Progress happens through shared documents, tickets and short focused calls, so a time difference costs you nothing.

Selected work

A sense of the kind of problem I take on.

Client names withheld. Happy to talk through any of these in detail on a call.

Retail · Market entry

New-country launch on Dynamics 365

Finance workstream for a major European retail group opening operations in a new market — system configuration, reporting structure and local requirements.

Financial modelling

Valuation model for a new venture

Full valuation and forecasting model built and stress-tested in a fraction of a traditional consulting timeline, delivered ready for investor review.

Multi-jurisdiction

Concurrent remote engagements

Ongoing finance and systems work delivered simultaneously for clients in the Gulf, North America, Africa and Western Europe — entirely asynchronously.

About

Paweł Kaniuk

I read banking and finance at the Warsaw School of Economics and started my career at PwC in Amsterdam, in audit and assurance and then transaction services. I spent around twelve years in the Netherlands, first in practice and then as an independent contractor.

In 2015 I moved to London and rebuilt a client base there across financial control, systems implementation and project management. Today I work remotely for clients worldwide, splitting my time between the UK and Spain.

Finance and systems stopped being separate disciplines a long time ago. Most of the problems I am called in for sit exactly on that line — a model nobody trusts, an ERP rollout with no finance voice in the room, a close that takes three weeks longer than it should. That combination of a qualified finance background and hands-on systems delivery is the reason clients call, and it is what I have built a career around.

Get in touch

Tell me what is on your desk.

Send me a short note — what the problem is, what system or numbers it involves, and roughly when you need it. I’ll come back within a working day with an honest answer on whether I can help and what it would take. If it is not something I am the right person for, I will say so.
