About me

Since 2018 I have helped online stores earn more. I start with data and finish with a result in revenue. Along the way I build what you actually need: a strategy, a store or a system.

02Pillars

From strategy to a store that sells

I start with strategy. The store, the systems and the website are the tools I use to deliver it.

03Services

All services, with prices

Start with one service or hand me the whole thing: strategy, the store, systems and ongoing maintenance. Prices are final: I am VAT-exempt, so no VAT is added.

Systems I integrate

  • WooCommerce
  • Allegro (Polish marketplace)
  • BaseLinker (order management hub)
  • Amazon
  • Comarch Optima (Polish ERP)
  • Symfonia (Polish ERP)
  • Make
  • Zapier
  • REST API

I’m a good fit if

  • you have a store that already sells and you want to grow without chaos
  • your team retypes a lot of data between systems by hand
  • you want one person accountable for the result

I’m probably not a fit if

  • you’re looking for the cheapest template website
  • you only need social media management

08Questions

Frequently asked questions

Answers to the questions I hear most often.

How much does working with you cost?

The ecommerce audit has a fixed price of €700. It is the final price: I am VAT-exempt, so no VAT is added. I quote implementation after the audit or after the brief, and you’ll find ballpark prices for each pillar above. If you hire me to implement the changes after the audit, I deduct the audit fee from the project price.

How long does a project take?

An audit takes 10 days. A store usually takes 6–10 weeks, an integration 2–6 weeks and a system 8–12 weeks, depending on scope. You get a detailed schedule with the quote.

What if there are no results?

I don’t promise numbers before the audit, because I don’t know your data yet. After the audit you know what to fix, in what order and what it could be worth. You decide whether to go ahead with implementation.

WooCommerce or Shopify?

I usually recommend WooCommerce: full control over your store, no platform fees on your sales and easy integrations, including with Polish systems. Shopify can be faster to launch with a simple catalog. We choose in the audit, based on your scale and integrations.

Do you work with companies outside Poland?

Yes. I work remotely with companies across the EU. We talk in English, the quote, contract and invoice are in EUR, and we meet online. I work on Central European Time (CET).

Do you work alone?

Yes. I’m responsible for the project from start to finish, and I’m the person you talk to. On larger projects I work with proven specialists.

What does a store build include?

Design and development on WooCommerce, payments and shipping, tax setup, SEO and analytics basics, product import and training. We agree on the exact scope after the brief, and every item is in the quote.

Which systems do you integrate with?

Most often WooCommerce, Allegro (Polish marketplace), BaseLinker (order management hub), and Comarch Optima and Symfonia (popular Polish ERPs), plus anything with a REST API or Make. If your system has an API, it can almost always be connected. I check that before I quote.

What happens after launch?

I can take over website maintenance on a monthly plan: updates, backups, monitoring and fixes. You see work status and documents in the client panel.
