I took over the B2B platform from the previous contractor and got it back on its feet: the store, operations dashboard, orders, and manufacturers now work reliably. The client has its own hosting, its own code, and a plan for further development.

The rehabilitation equipment store moved from the closed Shoper platform to its own platform: store, admin panel, and API in one project. The catalogue, orders, and content were migrated one-to-one, while payments, shipping, and feeds operate without plugin limits.

The ventilation wholesaler's WordPress site could not keep up with its B2B offering. I kept it as a convenient editorial backend, while a fast, modern frontend took over offer presentation, categories and quote requests.

My own system for freight forwarding and transport companies: orders, carriers, invoices, fleet, documents, and reports in one place. Each company works in its own isolated account, with separate customer portals.

A CSRD reporting tool for a large industrial group covered by an NDA. The platform collects ESG data from multiple companies, tracks tasks and deadlines, and produces a complete, auditable report with charts and a PDF.

Malta Trading wanted to move from WordPress and WooCommerce to a proprietary store under its own control. I took over technical support and built an e-commerce platform with a catalogue, customer accounts, payments, discounts, a blog, and support tickets.

A project taken over from a company that neglected a store connected to the client's operational systems. I am rebuilding its foundations and the automotive parts e-commerce store for the German market, with a catalog and customer account.

Proxy Poland provides Polish mobile 4G/5G proxies on real carrier modems. I connected the offer presentation to payments, automatic service activation and IP rotation in the customer dashboard.

A catalog and website collecting inquiries for a German power technology manufacturer. I migrated the site from outdated TYPO3 to WordPress, completed the product database, added a Polish version and improved loading speed.

A family-run campervan rental business in Kwidzyn: a Fiat Ducato fleet, clear pricing, route ideas around Masuria, Kashubia, and the Baltic coast, and quick contact with the owners without unnecessary forms.

A virtual voice receptionist for beauty salons: answers calls, manages appointments in Booksy, and drafts message replies. I configure the client's setup in one day, with pilots from PLN 499 net.

A store for roof racks, roof boxes, and Thule and OEM systems. The website guides customers from their need—bikes, skis, or rooftop luggage—to a specific setup, with the sale completed in the OLX store.

A store selling branded electrical products and lighting: promotions, extensive categories, customer accounts, and wishlists. A separate manufacturer path collects brand applications, while an accessibility widget makes shopping easier.

An operations dashboard for MSS built on my CoreTSL engine. Intermodal imports, intermodal exports, and road transport share a single view, order numbering, statuses, and documents.

M2 Radar collects property transaction prices from the Polish Property Price Register nationwide. Enter an address, compare zł/m² within a radius, and generate a PDF report for the client using real transactions rather than listings.

For B2 Inwestycje, I created a website focused on credibility and making the offering easy to understand. The project clearly presents the scope of work and quality standards, and guides users directly to contact.

The blog needed to stay on WordPress while becoming much faster. I added Astro as a lightweight frontend: posts are still written in the familiar admin panel, while readers get a website that opens immediately.

Fabryka Schabowego needed a site showing its food, menu and character without technical fireworks. I focused on large photographs, a readable menu and convenient mobile contact.

Nomad Camper needed a website that sells a style of travel while leading visitors straight to availability, pricing, and contact. I built the messaging around a specific campervan, a clear booking button, and a convenient mobile experience.

For a client under NDA, I connected KSeF 2.0 to a campervan and campsite booking platform. Invoices are generated automatically from bookings, submitted to the Ministry of Finance, and locked against editing after submission.

Mystic Dune Adventures needed a site capturing safari excitement while organizing routes, FAQs and contact information. It combines a striking first screen with a practical structure for inquiries.

Raban Szczecinek needed a website that quickly presents attractions, rules, prices, and contact options. I created a site for families, schools, and groups, with a clear route from inspiration to enquiry.

I structured MMA Markt as a product-focused site: simple navigation, clear categories and an offer for customers who want to quickly find equipment or accessories and place an order.

eBigSport needed a website that would not lose users between categories. I organized the presentation layer, made it easy to use on mobile, and prepared the project for search and campaign traffic.

Wake Wakacje needed a website that sells the experience while remaining practical. The offer, dates, location, and contact details are immediately available without scrolling through multiple screens.

Kryształ Szczecinek needed a simple, trustworthy site. It presents the local offer, services and contact details so nearby customers do not have to search.

Oskar Sprinkler operates where a website must build technical trust. I structured the offer so an investor or contractor can quickly understand the scope and start a conversation.

Dacho-Pest needed a website that explains its services simply and makes contact easy. Users should immediately know whether the company can solve their problem and how to book a service.

Performance optimization of an existing law firm's WordPress website: faster loading, better Core Web Vitals, and a lighter frontend, without rebuilding its services, content, or visual identity.

A W3C design token architecture and a library of 60+ components accessible to WCAG 2.1 AAA standards. It cut time to market by 42% for 14 product teams.
