Bairesoft, a Spanish company specializing in turning ideas into digital solutions, has taken a significant step forward in modernizing its systems by adopting K2BTools’ Service Builder.

The Challenge: Migrating Legacy Systems and Optimizing Resources

‍

Like many companies with legacy systems, Bairesoft faced the challenge of migrating its legacy applications to newer versions of GeneXus, improving the user interface, and delivering PWA applications for multiple devices. “Migrating parts of our ERP to GX 18 from older win versions was becoming increasingly difficult, so we started exploring alternatives,” explains Juan Pedro Iriarte, CEO of Bairesoft.

Manual API development and CRUD management were complex and resource-intensive. “Developing APIs consumed a huge amount of resources. The alternatives offered by other patterns didn’t work well for us; CRUD management was complicated. After trying Service Builder, we saw a significant improvement in performance,” Iriarte highlights.

Adoption Process: Integrating AI and New Tools

‍

Adopting Service Builder marked a shift in the team’s workflow, which had previously relied exclusively on GeneXus. “We’re still in the process of adapting our way of working. We always used GX, and now we’re incorporating external tools like Claude 4.5 and Windsurf.ai in the latest versions… It feels like we’re making faster progress every week,” says the CEO.

Currently, Bairesoft is leveraging Service Builder, which, according to Iriarte, “generates code up to 20 times faster and with higher quality,” integrating AI technologies such as SWE-1.5 with Claude Sonnet 4.5.

Results: Dramatic Time Reduction and Improved Quality

‍

The benefits of implementation quickly became apparent. “For example, what used to take us around 30 hours to manually develop an API and the code for a transaction with its work panels, now takes just 6 to 8 hours using the development cycle, GX18, Claude, and Windsurf,” says Iriarte. He also notes, “The quality of the code has improved exponentially, and as a result, our productivity has soared.”

Operational Impact and Customer Satisfaction

‍

For Bairesoft’s clients, the transition has been seamless. “They’ve only noticed the visual improvements and haven’t experienced any latency in their daily work,” assures Iriarte.

‍

Looking Ahead and Recommendations

‍

The positive experience has led Bairesoft to recommend Service Builder to other companies. “Based on our experience—short but highly effective—I fully recommend it. We look forward to continuing to work with this tool alongside various AI models and coding agents,” concludes Juan Pedro Iriarte.

‍

K2BTools’ Service Builder is thus established as a key solution for companies seeking to accelerate their digital transformation, optimize resources, and enhance the quality of their developments by integrating the best of artificial intelligence and low-code within the GeneXus ecosystem.
