Santiago Moreno Arce
Senior Software Developer · Software Architect
Senior partner for backend, Odoo, eCommerce and applied AI work. Usually replies within 24 hours.
Santiago Moreno Arce is a senior software developer and technical founder with more than 15 years of experience building, maintaining and improving real business systems.
He started writing code professionally at 18 and has been shipping software ever since — long enough to have lived through several technology cycles, debugged systems in production at 3am, and learned what actually matters when software has to keep running for years, not just demo well in a slide.
His work spans backend architecture, system integrations, Odoo implementation and customization, eCommerce platform development and business process automation — with a growing focus on applied AI that solves practical operational problems.
Over the years, Santiago has worked with companies across retail, B2B commerce, logistics and SaaS — building the kind of systems that run quietly and reliably in the background while business teams focus on what they do best. That breadth, accumulated across more than a decade and a half, is what lets him recognize patterns quickly and avoid the mistakes a first-time approach would inevitably hit.
What distinguishes his approach is the combination of technical depth and product and business understanding. He has not only written code — he has also shipped products, dealt with production incidents, planned migrations and made architectural decisions with real consequences.
This experience shapes how he approaches every engagement: understanding the business context first, then designing technical solutions that fit reality rather than idealized conditions.

Based in
Born in Murcia, Spain. Currently based in Spain — though you'll find him in Istanbul half the time, working from a café with a laptop and a coffee.
Own products
Santiago also builds his own products, including Kelvia.ai, an AI-focused project that keeps him close to real product, automation and business challenges.
What he values
The principles that guide technical decisions.
Maintainability
Code that is easy to change is more valuable than code that is hard to change, regardless of how clever it is.
Clarity
Clear systems, clear boundaries and clear documentation reduce risk and improve team velocity over time.
Reliability
Business systems need to work consistently. Reliability is not a feature — it is a fundamental requirement.
Business impact
Technical decisions should be grounded in business context. The best technical choice is the one that delivers the most value given the constraints.
