Co-inventor and builder of financial technologies. Executive roles across the FX and CFD industry, financial products developed for complex regulatory environments, and large language models put to work in them.
Appearances, international media and associations
A stepped elevation field standing in for the systems behind the work: multi-asset liquidity, algorithmic models and execution signals, quantised into three tones. Move across it to send a ripple through the grid.
Executive roles that show the range: a copy-trading platform built to European regulatory standards, fractional private equity structured across jurisdictions, and the distribution network of a European FX and CFD federation.

Advisor to Rechtsanwalt Sascha Müller on financial and crypto institutions.
The work starts with a situation, not a feature list. Software is cheap now. A product that holds up in front of a regulator, a counterparty and an auditor is not.
Two rooms.The lawyers wrote the application. The developers wrote the platform. Each side handed the other a document and hoped the translation held. When the auditor arrived, the gap between the two was where the findings lived.
One room.Compliance became a property of the engine: risk tiers in the matching logic, liability protection in the replication path, audit trails as first-class data. The regulator's questions were answered by the architecture, not by a binder.
Software is cheap now. A compliant product is not.Anyone can ship a feature in a week. What takes a decade across distribution, regulation and capital is knowing which feature turns compliance into a liability, and saying no to it before it is written.
Built for my own use first, then automated end to end. No team to manage and no sales process: usage is the marketing, and the products maintain themselves.
A phone-first card where every element drills into a full-screen view, with no page reloads: save the contact, book a call, see the work. Built for my own card at card.winzker.net, and passed on from there.
The BeaconSignificant regulatory news for the FX, CFD, banking and investment industry, aggregated automatically from official regulator records worldwide, with a check of whether a firm is really authorised.
My own regulatory articles are published there too.
