How this works

One engineer, the full stack, and no handover to a junior

The catalogue is wide because the work has been

Thirteen years across Shopify, WordPress, WooCommerce, Magento, Node.js and PHP produces a wide list. Every entry here is something already built at least once in production, not a keyword page. Where a service is newer to us than the rest, the page says so rather than implying a decade of it.

Scope first, then a number

Pricing depends on what is actually there, so the first step is a short written scope: what exists, what should change, what counts as done. Fixed-scope work gets a fixed price. Project work gets a range with the parts broken out. Ongoing work gets a monthly commitment. No discovery call is required to get that far.

Direct, not through an agency layer

You talk to the person writing the code. For larger builds we bring in developers from a network built over thirteen years, and the accountability stays in one place. Contracting is business to business through a registered sole proprietorship, which is what most direct-hire briefs ask for.

What we do not promise

No guaranteed rankings, no guaranteed approvals, no guaranteed compliance. Where a result depends on Google, Shopify, Meta or a regulator, we can build the strongest case and fix the technical cause, and the decision still belongs to them. Anything compliance-related here is engineering work and an informational tool, not legal advice.

Questions

Before you write

It depends on the scope, and a number without a scope is a guess. Send a short description of what you have and what should change, and you get a written scope with a price or a range. That part is free and does not require a call.

Small fixed items usually run in days, projects in weeks. You get an estimate with the scope, and if something turns out larger than it looked, you hear it when it is discovered rather than at delivery.

Yes, white label included. Contracting is business to business through a registered sole proprietorship in the EU, invoiced monthly or per milestone.

Ukrainian and English for correspondence and documentation. Building for German and Polish markets is routine here and this site is published in four languages, but the working language between us is one of the first two.

Yes, and that is most of the work. It starts with reading what is there and writing down what we found, including the parts that are fine, so you are not paying for a rewrite you did not need.

Describe it anyway. The list covers what has been built before, not the limit of what can be. If it falls outside what we do well, you get told that instead of a quote.

Tell us what needs building

Send what exists and what should change. You get a scope and a price back, not a discovery call.

A tool, not legal advice - no guarantee of compliance.
