Józef Chełmoński, “Storks”, 1900. National Museum in Warsaw. In the painting: a ploughman sitting in a meadow breaks off his meal and, together with the boy standing beside him, looks up at the storks flying past; in the background, oxen at the plough and village cottages.

The plough can wait.

The ploughman put down his spoon and the boy looked up: storks were flying over the field.

We design and build web applications, internal systems and automations that let a team look up from repetitive work.

Take the tour

The same job every morning: retype, copy, check, forward. A machine will do that part.

Jan Matejko, “Stańczyk”, 1862. National Museum in Warsaw. In the painting: the court jester, dressed in red, sits in an armchair, deep in thought, while a ball goes on in the background.

Clever.

Clever · Code · Craft

At the ball everyone is dancing. One man has read the letter lying on the table and already knows what is coming. Clever is not cunning; it is seeing a problem before it gets expensive.

Stanisław Wyspiański, “Apollo. The Copernican System”, 1904 — a stained-glass design for the Medical Society House in Kraków. National Museum in Kraków. In the painting: a golden Apollo — the Sun — bound to his lyre and, around him on blue orbits, figures personifying the planets.

Code.

Clever · Code · Craft

Wyspiański laid out the Copernican system for stained glass: the Sun in the middle, the planets in orbit, each piece of glass in its own lead frame. That is how we write code: in parts you can replace without breaking the whole window.

Józef Mehoffer, “The Strange Garden” (detail), 1902–1903. National Museum in Warsaw. In this detail of the painting: a sunlit orchard with garlands of flowers, a woman in a sapphire dress reaching for an apple and a huge golden dragonfly hovering above her.

Craft.

Clever · Code · Craft

Mehoffer was a stained-glass artist and painted like a goldsmith: every vein in the dragonfly’s wing, one by one. Nobody would have noticed if he had not. In software, too, you only see the details when they are missing.

Jan Matejko, “The Hanging of the Sigismund Bell at the Cathedral Tower in Kraków in 1521”, 1874. National Museum in Warsaw. In the painting: on the left the royal court watches the work, in the centre stands a man with a roll of plans, on the right workmen pull on the ropes, and the great bell rises beneath the scaffold, watched over by the bell-founder.

How we work

First the plan. Then the ropes.

Over ten tonnes of bronze, a scaffold and one man with the plan in his hand. The court watches, the workmen pull. In 1521 nobody talked about methodologies, and the bell hangs to this day.

Conversation

First we look at how you really work. Not at what the procedure says.
Plan and price

We draw up the plan and quote a fixed price. You know what you will pay and what you will get before we lift anything.
First lift

After a few weeks a working system is running in your company. You test it on real work, not in a presentation.
Care

After launch we stay with the system and develop it as your company grows.

Leases are signed for years, premises chosen by eye. This tool works out how far you can really walk or drive in 5, 10 and 15 minutes, how many people live there and how many competitors already trade. The result: one score, 0–100. This Wrocław address got 60.

IZAR has made current-carrying connections since 2000 and used to keep what it knows about them in a PDF catalogue, where a search engine loses the layout of the tables. On the new site the catalogue is text: 253 table rows in which every number can be found.

C3S, CRM for a Key Account Manager, 2026, Next.js, Supabase, client’s private collection.

A manufacturer’s Key Account Manager looked after customers from one Excel file with seven tabs. Now every contact goes on a timeline, sales are on a board, and the weekly report compiles itself. Carried over from the spreadsheet: 100% of customers and orders.

A seasonal retailer, several outlets, a short season and goods that cannot wait until tomorrow. Tills and stock levels for every outlet in one system. Today thirteen stalls cash up without a single sheet of paper, and the owner sees the takings live.

About the exhibit

Stanisław Noakowski, sketch from the portfolio “Architektura polska. Szkice kompozycyjne” (Lwów–Warsaw, 1920), drawn in 1916, shown here on an extended sheet. National Library of Poland (Polona). Ink drawing on cream paper: an imagined Renaissance palace with two corner towers and arcades.

Why C3S

The plans stay with you.

Noakowski drew a palace that nobody had commissioned. Any architect could build it from a sketch like this. It is much the same with us: when the project ends, you get the full source code, the database, the copyright and the documentation. You go on building with us or with anyone else.

Time to build: first version in 2–⁠6 weeks
Estimate: initial analysis and estimate in 48 hours
Ownership: code and data 100% owned by the client

Jan Matejko, “Astronomer Copernicus, or Conversations with God”, 1873. Jagiellonian University, Collegium Novum. In the painting: Nicolaus Copernicus at night on the terrace of his observatory, one hand raised, gazing at the starry sky; beside him, a board with the heliocentric model.

Copernicus had an idea for a system, too.
