CUSTOM WEB APPLICATION DEVELOPMENT

What we do

We help companies and professionals to carry out their digital transformation with custom software developments.

The software packages you found don't work the way you want them to? Do you think you could automate many tasks if you could connect several software that you are using? Do you have a business idea that doesn't exist? We can help you.an help you.

HOW WE DO IT

The software we develop is made following quality standards that seek excellence:

UX

We take great care of the user experience to make using our applications the most intuitive and rewarding.

Responsive

We develop applications that are fully functional on desktop, mobile and tablet, making the most of each device.

Infrastructure

A good, fast, secure, reliable and scalable cloud infrastructure is vital for the success of an Internet project.

Security

A project on the internet is useless if the security of both the software and the infrastructure in which it runs is not up to par.

Agile

We use Agile methodology for development which allows us to face changes in requeriments in a natural way.

Quality assurance

We program automated tests to guarantee the correct operation of the application at all times.

What technologies we use

Software is not just a bunch of lines of code. There is a structure, a software architecture that guarantees the scalability and maintainability of the project over time.

We use the tools that allow us to obtain the best results, those that make us more productive and best if they are open source tools that are widely adopted. We stick to the standards and develop the front-end and the back-end separately. All this allows the project to be easier to update and maintain and to have a longer lifespan.

Who we are

We are a custom software development company in Barcelona with more than 20 years of experience and passion for what we do.

The founders trained as computer engineers in the 90's, we had our first contact with the Internet in college. In those days when some of us had a modem at home and we connected to BBS 's, the idea of the Internet promised to be revolutionary.

And surely it was. It became our way of life, and it still is today. We started working on the first ISP's that appeared in Spain, to go on to work in technological start-ups in the middle of the bubble .com at the entrance of the XXI century.

After that it was time to start something new, simple and honest with ourselves and our clients. This is how Zentense was born in 2001.The next 20 years are a story of challenges, struggle and overcoming, but above all of learning and improvement continues. And here we are now, in the middle of the revolution of the internet of value and the blockchain.

We hope that in the future you will be part of our history.

The time had come to start something new, direct and honest with ourselves and our clients. This is how Zentense was born in 2001.

Why Zentense

These are the reasons that make us a good choice:

Because we make custom software

Being custom, you get the application you need, no more, no less. They will say that it is expensive and slow to make custom software. As for the first point, how cheap is something that does not work well or does not do what you expect?, and as for the latter, sometimes it is almost as costly to adapt an existing application than to start a new one, and of course, we use libraries and frameworks that accelerate development.

Because of our experience of more than 15 years

And since then many things have changed and many new technologies we have learned to stay up to date, and above all, much we have had to learn from our customers to know what they need.

Because we are a small company

And we do not have the huge structure costs of the big consultants, we can react quickly to changes, and your project will not go from hand to hand. Some will say that a small company is at risk of disappear and your project would stall, but (see previous point), we are here to stay.

Because we like what we do

We like technology and we like to develop applications with it, and when you do things with love, it shows in the details of the end result.

Because we deliver on time

Many of our customers are from the events scene, and any event can be delayed even a single day, even a single hour. We know what is to work with deadlines and, above all, respect them.

Because we are honest

Because everything is not allowed to make money and we are a company that has very clear values. We are not going to promise you things that we know we can not fulfill.
