Herbal EssencesWhat clients say about
working with me
Clients value clear communication, reliable delivery and independent problem-solving.
I have been working with Marcin for years. Thanks to him I have a new, beautiful blog. He migrated me from an unintuitive, template-based WordPress to a brand new website he wrote specifically for me, tailored to my vision and needs. Marcin is a specialist who pays attention to detail and never overlooks even the smallest things.
On the new website he also built a shop with a complete payment module, so I can sell my product independently without paying commission to anyone. I highly recommend Marcin for anything related to your website.
We wholeheartedly recommend working with Marcin. We had the pleasure of completing three projects together and we keep coming back. We have been working long-term, so we know we can count on him in any situation - he always finds solutions to technical problems quickly and effectively.
I wish every collaboration were at this level - if someone wants something done well, efficiently, and without hassle, this is definitely the right address.
I didn't expect this website could look so good! Working with Marcin, I got a professional website with logically organized services and content.
On top of that, after a joint workshop, we added a new service I hadn't thought of before, and it has great potential. I'm really happy with the result.

FAQ
Frequently asked
Answers to the most common questions about working together.
- I can help with theme changes, new sections, bug fixes, performance work, app integrations, landing pages and custom storefront features. I also take on redesigns, migrations and larger Shopify builds.
- Yes, that's most of my work. I regularly step into existing Shopify stores, live theme codebases, to ship fixes, new sections, integrations and performance improvements without breaking what's already working.
- Yes. New stores, redesigns, platform migrations, and larger feature builds from idea to launch, with the same production-ready approach I use for everything else.
- Yes. I regularly work embedded inside agency and in-house teams as senior Shopify/frontend developer, picking up tickets, pairing with your other developers, and fitting into whatever workflow and tools you already use.
- Choose a block of development time based on what you need. I estimate tasks before starting, work through them in priority order, and keep you updated on time used. You can add more hours or move to ongoing support whenever needed.
- For most ongoing support, 10 or 20 hours is a good starting point. It's enough to make real progress and see how we work together before committing to anything longer-term. If you already know you need consistent, ongoing capacity, we can set that up directly instead.
- 10 hours usually covers a handful of focused fixes, a new section or two, or a small integration. 20 hours stretches further: several backlog items, a bigger feature, or meaningful performance work. Send me your list and I'll give you a realistic estimate before we start, so you know what to expect.
- Yes, anytime. We can adjust the time as we go.
- Yes. I regularly work alongside in-house designers, marketing teams and other agencies: implementing designs, picking up backlog items, or handling the frontend/Shopify pieces of a larger project.
- Yes. Most of my Shopify work is on Plus stores: custom themes, checkout customizations, and the kind of larger-scale builds Plus merchants typically need.
- Usually within a few days of us agreeing on scope. Reach out via the contact form below and I'll reply within 24h to confirm availability.
