How we integrate AI into our development work
Working with AI gives us superpowers, but judgment cannot be automated
We have been programming since 2004, and artificial intelligence has changed the way we work. This is what we apply in every project.
Judgment and review
AI makes us more productive, but our responsibility for what we deliver is the same. We review what it proposes and accept nothing without knowing why.
AI savings benefit the client too
If a task that used to take eight hours now takes two thanks to AI, we say so, and the quote reflects it.
AI where it adds value
Not everything is solved with AI. When the result has to follow fixed rules and always be the same, we program traditional algorithms.
Independence and privacy
Twenty years ago we did not want to depend on closed-source software; today we do not want the company to depend on an AI provider. And data privacy is discussed with the client before anything is integrated.
High standards
A 9 out of 10 on an exam is a top grade; a tool in which 90% of the features work is a failure. We do not consider a tool finished until all of it works.
Continuous learning and renewal
Since 2024 we have changed the way we work frequently, to bring in new AI tools and automations, not only to save work, but also to be able to deliver even more solid products, tested with the best development practices. We teach the younger people on the team to understand why something works, not just to validate it.
Tell me what website you have, and I'll tell you what kind of company you are
A website that speaks volumes about Gilsys
At the end of 2024, we launched a new website to celebrate Gilsys' 20th anniversary.
People have asked us: Why, if the previous one was still great?
Because the old one was 5 years old
This might not be a problem for most companies, but we strive to stay ahead, always applying the latest technologies to our own work.
Because we are a demanding company
We needed a website that reflected our high standards: something we could truly be proud of.
Because we wanted to test Astro
We're constantly innovating and exploring new technologies. We wanted to experiment with Astro and take our website to the next level.
Because we wanted a perfect score on Google PageSpeed Insights
At launch, we achieved a score of 100 for performance, 100 for best practices, 100 for accessibility and 100 for SEO in Google PageSpeed Insights.
Because the era of artificial intelligence has arrived
The rise of artificial intelligence is transforming the digital landscape, and we want to showcase how we can help businesses embrace it.
Because we wanted to move beyond WordPress
We have the technical expertise to build a fast, secure, and SEO-optimized website, so we did it.
