What I sell

Your entire engineering function

You have the domain. You have no engineering staff, and nobody who could direct one if you hired them. That is not a hiring problem, it is an evaluation problem, and hiring does not solve it.

I become the technical function: architecture, build, infrastructure, operations. A scoped deliverable with an end date and acceptance criteria, monthly and cancellable, company to company.

Proofsole technical owner and the only engineer in a team of 15 PhD scientists, with full lifecycle ownership while they stayed on their domain.

Tacit knowledge → system

The process that runs your business lives in three people's heads. It cannot be delegated, it cannot be scaled, and it cannot be written down as a spec, because the people who know it do not experience it as rules.

I extract it by building. Not by interviewing, and not from a requirements document.

Proofan executive assistant's slot-picking judgement became weighted constraint optimisation. A German real estate sales process became event and command queue orchestration. A research team's domain expertise became queryable knowledge graphs. Same method, three unrelated industries.

Scoped build: idea to production in months, not quarters

An agency quoted you six months and a discovery phase. You have a deadline before that.

A defined deliverable, built and shipped, with the architecture decided by whoever has to keep it running.

Proofa complete AI document-processing platform delivered in one month. A working CRM orchestration layer in the agencies' hands two months from the idea. A scheduling beta in one month, genuinely usable at four. A B2B data platform to its first paying client three months from the first line of code, on a pilot the founders brought in.

What I do not sell

Replaces a development team; does not manage one.

Out of scope

  • Implementing someone else's detailed spec with no architectural inputThe method depends on building the architecture as part of the engagement, not after it.
  • Permanent employmentEngagements are company to company, monthly and cancellable. There is no permanent seat for me inside the buyer's team.
  • IT operations or MSP workCustom development, separated. If you need someone to keep the lights on, the incumbent MSP is the right call.

Three engagement shapes for a single engineering function: the entire engineering function as an ongoing engagement; tacit knowledge converted to a computable system; and a scoped build from idea to production in months rather than quarters. Each carries the same engagement shape: scoped, with an end date and acceptance criteria, monthly, cancellable, company to company. Availability is immediate; the work is remote in an EU timezone, on a B2B or consulting contract. Out of scope: people management, implementing someone else's detailed spec with no architectural input, permanent employment, and IT operations or MSP work.
