What we do

Four areas we work in day to day: from a one-page site to a shop with online payments and tools that run in the background. Built from the ground up, and the code remains yours.

Websites & online shops

One-pagers, landing pages and company websites coded by hand, without heavy page builders. We also build shops: a product catalogue, online payments, an order panel and courier integrations. Everything loads instantly and works just as well on a phone as on a large screen.

  • Online shop
  • Online payments
  • One-pager
  • Landing
  • Company website
  • WordPress
  • Next.js

Performance, SEO & audits

We speed up existing sites to PageSpeed scores that stand comparison, whether they run on WordPress or something else. We run technical audits, improve Core Web Vitals and accessibility, and handle migrations. A slow site costs real customers.

  • Core Web Vitals
  • Technical audit
  • WordPress speed-up
  • Accessibility
  • Migrations
  • Technical SEO

Automation, data & integrations

Web scrapers that deliver data straight into Excel, CSV or a database. Automation of recurring processes in n8n and Airtable, payment and invoicing integrations, API connections between the systems you already use. Less manual work, more running quietly in the background.

  • Web scrapers
  • n8n
  • Airtable
  • API integrations
  • Invoicing
  • Data export

AI, extensions & maintenance

AI chatbots with contextual memory, on your site and on WhatsApp. Chrome extensions built to the MV3 standard. Diagnosing and repairing inherited code (WordPress, PHP, Python, scrapers), plus ongoing website care: updates, backups and monitoring.

  • AI chatbot
  • WhatsApp
  • Chrome MV3
  • Code repair
  • Updates
  • Backups

Our work

Deployments you can open and check for yourself. No mock-ups. More are added as they launch.

Shop rebuild Live

Prostnica

A rebuild of a woodworking-tool shop on the Shoper Storefront platform, measured against one thing: clicks to an order. Buying starts on the first screen, the variant picker and the buy button sit inside the listing tile, and checkout fits on a single screen with the summary in view. The catalogue filters by the job to be done rather than the catalogue name, and the technical drawing beside each product redraws its dimensions with the chosen variant. A separate view maps every layout element onto theme modules and says what needs a higher plan. Brand and catalogue are fictional.

Under the hood
  • Shoper Storefront
  • Buying from the first screen
  • Drawing tied to the variant
  • Theme module map

CRM application Live

EnergoLead

A lead-handling application where record visibility follows the stage of the workflow. An operator sees only the records assigned to them at the stage they handle — changing the status revokes access the same second, along with notes and call history. Reaching someone else’s record by URL is refused by the server rather than answered with an empty list. The “who sees what” matrix is computed from live data instead of describing intentions; beside it sit an event log and a CSV import with column mapping and duplicate checks by tax number. Four demo accounts open two different scopes of visibility. The company and its data are fictional.

Under the hood
  • Node with no dependencies
  • Access decided server-side
  • CSV import with duplicate checks
  • Event log

Book landing page Live

Decyzje na papierze

A single-page presentation of a handbook that sells the book by letting you try it. Five pillars of the method unfold into chapters, and the field for your own answer genuinely works: what you write stays in your browser and waits for you to come back — the same thing the book does with paper. The title card shows a typeset copy, the contents lead by page numbers, a calendar proposes dates to return to the reading, and the order form totals the bill live, delivery included. The title, author and imprint are fictional.

Under the hood
  • Static site, no framework
  • Answers stored in the browser
  • Live order total
  • Return calendar

Demo B2B site of an ERP partner Live

Ewiden Systemy

A demo site for an ERP implementation partner (company and product names are fictional), built around a register: six system areas and five industries get their own URLs instead of paragraphs on one long page. The first screen pairs a statement of the problem with the list of areas and how long each takes to implement. The schedule gives every stage a duration, an outcome and the work expected from the client, and an enquiry carries the context of the area being read.

Under the hood
  • WordPress
  • Custom theme
  • Areas and industries as content types
  • Structured data and sitemap

Screenshot of Iteracja

Workshop page Live

Iteracja

A page for a one-day workshop, added to a training company site. The programme takes the most space: the day laid out in hourly blocks, each marked with the role the trainer takes. Dates show the seats left and close sign-ups on their own once they run out, while a submitted form lands in the admin panel and returns to the sender with a reference number.

Under the hood
  • WordPress
  • Custom theme
  • Programme and dates from the CMS
  • Sign-ups with confirmation

Personal brand site Live

Marszruta

A site for a production planning consultant, built around the reader → subscriber → client path. Instead of a sticky header there is a fixed identity frame on the left, with the content scrolling in the lane beside it. Newsletter sign-ups go to beehiiv and stay in an in-panel register, articles get a table of contents and a reading progress bar, and analytics only start after consent.

Under the hood
  • WordPress
  • Custom theme
  • beehiiv
  • GA4 with consent mode

Store with integrations Live

AeroPrint

A boutique shop with aviation prints and apparel on WordPress and WooCommerce. A4/A3/B2 variants set price, weight and parcel size on their own, the checkout picks an InPost locker, and shipments from several suppliers merge into one delivery. VAT OSS accounting covers 27 countries and two currencies. A custom theme and nine modules instead of paid plugins.

Under the hood
  • WooCommerce
  • InPost ShipX
  • VAT OSS · PLN/EUR
  • Custom theme

Wholesale store Live

Profesjonalia B2B

A wholesale store for professional cosmetics, aimed at salons and massage studios. Prices sit next to the goods without a login: gross, with net in brackets, together with the full quantity-discount ladder. An order can start from a list of item codes pasted off an invoice, the cart recalculates thresholds and the customer-group discount on every change, and the checkout supports deferred payment terms.

Under the hood
  • Static, no framework
  • Tiered and group pricing
  • Quick order by item code
  • WCAG 2.2 AA accessibility

Store design Live

Barwnica

A concept store for a balloon-decoration wholesaler whose catalogue is organised by colour. The first screen is a full-bleed project photo with clickable colour hotspots, and the swatches themselves are balloons rather than paint chips: rounded, with a highlight and a knot. Plus a scratch palette holding six shades side by side and a calculator turning garland metres into balloon counts. A separate view maps every section onto the modules of an off-the-shelf theme on a closed store platform.

Under the hood
  • Shoper Storefront (NORD)
  • Colour-filtered swatch book
  • Garland calculator
  • Module implementation map

One-page site Live

iElektro68

A dark, “electric” site for the electrical contractor Instalacje Dworzyński: a project gallery, a quote form and content managed from the admin panel. A custom WordPress theme written for this one site, with no page builder.

Under the hood
  • WordPress
  • Custom theme
  • Form + gallery (CMS)
  • Email (Brevo)

Online store Live

BioTarget

An organic food and superfoods shop on WordPress and WooCommerce. A custom theme written for this store, with no page builder: a bespoke home page, product page, cart and checkout with cash on delivery. Products and content are managed from the admin panel.

  • Custom theme
  • Cash on delivery

Store + club site Live

Fitness World

A shop and club site for a gym on WordPress and WooCommerce. Memberships as variable products (open, student, senior), a store with supplements and accessories, a class schedule and a blog. A custom theme in a dark, industrial style, plus an in-house page micro-cache for speed.

Under the hood
  • WordPress
  • WooCommerce
  • Custom theme
  • Variable memberships

Service site, local template Live

BrukClean

A site for a paving-cleaning company, built as a template for local landing pages: one city, one page, duplicated without writing new code. Shared data sits in options, the differences in page fields, and a built-in check keeps the copy for neighbouring cities from being copies of each other. Elementor free edition, logic in permanently loaded modules.

Under the hood
  • WordPress
  • Elementor (free)
  • City template
  • Local SEO · JSON-LD

From the first conversation to a live site

Three stages and a predictable path. At each one you know what is being built, how long it takes and what happens next.

  1. Stage 1

    Conversation and quote

    We establish what the site is for and which features it needs: a product catalogue, payments, a blog, bookings or integrations. You receive a specific quote together with a timeline, with no obligation.

    usually 1–2 days

  2. Stage 2

    Design and build

    First a layout design for your approval, then code written from scratch. Along the way we test on real screen sizes — from a small phone to a large monitor — and for speed and accessibility.

    usually 1–3 weeks

  3. Stage 3

    Launch and care

    We publish on a server with an HTTPS certificate and set up the domain, email and analytics. We hand over the code and the credentials. They are yours. If you want, we stay with the site: updates, backups and small changes.

    launch within a day
