How we work

From the first call to a working product

The same pattern for a website, an online store and an application — the scale changes, the order does not.

1

Conversation and scope

We reply within 24 hours. On the first call we agree what the product has to achieve and what must be in the first version — and what can wait. That becomes the quote: a fixed price or time and materials.

2

Design

Wireframes and UI design are made in-house, so they do not drift away from the implementation. For public-sector websites we design for digital accessibility (WCAG) from the first mock-up, because bolting it on at the end costs more.

3

Short iterations

We show a working version every one to two weeks instead of one big hand-over at the end. The first version reaches users fast: the Bezuma store in three weeks, the LGD Gorce-Pieniny website in two.

4

Launch and maintenance

Code, repository and cloud accounts are set up in your company’s name — changing vendors never means starting from scratch. After launch we maintain the infrastructure, monitor it and keep developing the product on an hourly basis.

Technologies

A stack that can be maintained for years

We pick tools for the goal of the project, not for fashion — and ones another team can take over without starting again.

Web applications and SaaS

React, Next.js, Node.js, TypeScript, PostgreSQL. This is how we built DetailingFlow, our own SaaS product, among others.

Mobile apps

React Native and Flutter when one codebase has to run on Android and iOS; Kotlin and Swift where maximum performance matters.

AI and automation

Large language models, assistants working on the company’s own documentation, automation of repetitive processes — from a process audit to deployment.

DevOps and cloud

AWS, Microsoft Azure, Google Cloud, Docker, Kubernetes, CI/CD, monitoring and backups. Infrastructure is set up on the client’s own account.

Websites and stores

Strapi as a headless CMS for applications; WordPress and WooCommerce where the client edits content and runs sales on their own.

Design

Wireframes, clickable prototypes, design systems and visual identity — designed for accessibility and for the implementation that follows.

Who we work with

Industries we have already worked in

Projects from very different worlds — the common denominator is a deadline we kept and a result that can be measured.

E-commerce

Bezuma online store: from zero to sales in three weeks, over 400 users a day one month after launch.

Tourism and transport

Bus-Koncert: a coach booking website rebuilt in four weeks — the one feature customers come for now works.

See the case study →

NGOs and public institutions

LGD Gorce-Pieniny: a website meeting digital accessibility requirements, from design to launch in two weeks.

See the case study →

Local services and automotive

DetailingFlow: our SaaS product for car detailing studios — calendar, online bookings, SMS, a detailer app and a studio website.

HR and administration

An AI assistant working on HR documentation cut a payroll team’s monthly work from more than two days to three hours.
