SWEHQ - Software Engineers High Quality

What we do for you

We are Software Engineers who care about quality of the apps you need. Either it’s a feasibility prototype or a long-term goal, we go to the point, and write production-quality code any other developer can contribute to.


Browser is the operating system of the future, its ecosystem is huge, and we love both algorithms and user interface.

We build functional and usable mobile and web apps.

Code quality is essential for long-term projects, the effort we put into writing always pays off.

Solutions should be as complex as the problem they solve. That’s why we love Occam’s razor and KISS principles.



Our favourite languages and platforms are JavaScript, TypeScript, Python and SQL.


We focus on web, mobile and progressive web apps – imagine native apps running in the browser.

Typically, we use Angular, React, Vue.js, Django, or Flutter, yet have experience with many other technologies.

We limit the number of technologies used to the minimum, use common code, or generate code we do not need to write, and share a code base among apps running on different platforms.


If you want a fast prototype, we focus on the core of the problem and the speed of delivery.

If you want a complex and sustainable solution, we focus on quality and innovation.

The user of the software is always in the centre, and we need to understand his or her story. We think ahead, and produce code that will continue to run for years, and that any new developer can contribute to without complex training.

Code readability is the key, it’s always reviewed by at least 2 developers.

As a vendor we are always ready to pass the code on to someone else = no vendor lock-in.

The functionality of the software is covered by automatic tests that give you a guarantee of quality, and developers the freedom to make systematic changes if needed.


Decisions have a technical basis

We always make common decisions with the client. They need to be on point, and have to be realistic in terms of technical possibilities.

Focus on engineering and product

We focus on engineering while in direct touch with the product vision.

Minimize managerial overhead

Although we have also worked in diverse managerial roles, as engineers we are sure code and functionality are always the best argument.


We have built or contributed to the following projects


The new iteration of the biggest auction portal in the Czech Republic.


A language exercise book for Czech language learners learning Czech in the Czech language. Words, definitions, and morphology for both youngsters and adults.


Large web app for complex financial advisory with many modules and 3rd-party integrations.

Delivery Centre for Makro

An internal tool for processing orders coming to the new delivery centre.


Redesign and rework of the UI of a very complex DMS used by 100s of public institutions like Czech State Social Security Administration, biggest health insurance company, hospitals, and municipalities.


An internal project management tool used in Google corp.
