Finance & Systems Consulting
We build the financial models, lead the system implementations and fix the finance processes that sit behind them — senior people working directly with you, not a layer of junior consultants.
Remote engagements worldwide · Part-time, project or interim · Replies within one working day
Services
Most engagements start with one of these and grow from there. Scope can be a single deliverable or an ongoing part-time commitment.
Audit-defensible models that stand up to scrutiny from a board, a lender or a due diligence team.
The finance side of a system programme — requirements, design, data and the people using it.
Making the monthly cycle faster, cheaper and less dependent on one person's spreadsheet.
A senior pair of hands to own a finance or systems programme end to end.
How we work
Every engagement is led and delivered by a senior practitioner. The person you speak to on the first call does the work — no pyramid, no handover to a team you have not met, no learning on your budget.
We use AI heavily for model construction, analysis and documentation, which compresses timelines dramatically. Every output is reviewed and sense-checked by a qualified accountant before it reaches you. You are buying the judgement, not the keystrokes.
We work with clients across many time zones, from North America to Asia-Pacific. Progress happens through shared documents, tickets and short focused calls, so a time difference costs you nothing.
Selected work

Ongoing finance and systems work delivered simultaneously for clients in the Gulf, North America, Africa and Western Europe — entirely asynchronously.
Founder
Apex Financial Architecture was founded by Paweł Kaniuk. He read banking and finance at the Warsaw School of Economics and started his career at PwC in Amsterdam, in audit and assurance and then transaction services, before spending around twelve years in the Netherlands, first in practice and then as an independent contractor.
In 2015 he moved to London and built a client base there across financial control, systems implementation and project management. Today the practice works remotely for clients worldwide, from the UK and Spain.
Finance and systems stopped being separate disciplines a long time ago. Most of the problems we are 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 the practice is built around.
Get in touch
