You’re not looking for a programmer. You’re looking for someone who understands your business.
I’m Piotr Dejneka, a freelance ecommerce consultant and WooCommerce developer. I’m a computer science engineer who came to building systems through the warehouse, marketing and running an online store. That’s why I design solutions that make money and save time, not ones that just work.
I know every side of ecommerce from the inside
I didn’t start with code. Before I built systems, I worked in the places I design them for today.
- Stage 1
Warehouse and logistics
I started as a warehouse worker. I know what a day looks like when the shipping label won’t print and the system can’t see the stock.
I design so the warehouse team actually wants to use it.
- Stage 2
Design and marketing
As a graphic designer and online marketing specialist, I learned that the best code is worthless if the site scares customers off and the funnel leaks.
An interface has to sell, not just look good.
- Stage 3
Ecommerce management
I manage online sales day to day. I understand the P&L, margins and the pressure to deliver results, because I’m accountable for them myself.
I know what a business needs from technology.
- Today
Systems engineering
I bring this experience into stores, integrations and my own software. I build tools that solve problems I’ve run into myself.
One person from strategy to code.
I bring the view of a warehouse worker, a marketer and a manager into one project.
I build trust with facts
My testing ground: Dottore, a beauty brand from Poznań
At a fast-growing cosmetics brand, I designed and implemented the whole technology ecosystem, from the warehouse to multichannel sales. I wasn’t just a contractor. I was responsible for the architecture.

No need to ask “where is my project at?”
In this industry, delays and silence are the norm. With me, transparency is.
- One person accountable
You talk to the person who designs and builds it. No handoffs between departments.
- Everything in the client portal
Tickets, hours worked, billing and system status in one place, available at any time.
- Decisions based on data
Before I change anything, I measure. After the change, I check whether it worked.
- I tell you when I’m not the right fit
If someone else would do it better, or the project doesn’t make sense, you’ll hear it before you get a quote.
- Continuity without downtime
With a maintenance plan, monitoring alerts me to outages, and the response time is set in the contract. On larger projects I work with trusted subcontractors, but I stay accountable for the whole.
The tools I use
I choose proven technologies that can be maintained for years.

Discipline
I live in Poznań and work remotely with clients in Poland and abroad. When I close my laptop, I go to the gym or the soccer field.
Sport taught me that results come from steady work, not bursts. I approach projects the same way.
In life, as in code, I don’t like chaos.
