About Me
I'm a Senior Software Engineer based in Mexico City with 13+ years of experience building scalable applications. I specialize in architecture, high-performance systems, and engineering strategy.
Throughout my career at companies like Kueski, Clip, and Linio, I've architected applications ecosystems supporting millions of users, optimized high-traffic applications for sub-second latency, and engineered mission-critical fintech modules that process thousands of transactions daily.
I'm passionate about building design systems, establishing engineering best practices, and mentoring teams to deliver high-quality software. I believe great engineering is about making complex things simple and empowering teams to move fast with confidence.

Testimonials
“I had the pleasure of being Beto's manager while he led the Merchant Experience team at Kueski. From the outset, I was impressed by his proactive, constructive, and inquisitive attitude. He quickly detected flaws and issues in our codebase and developed a comprehensive migration plan, considering security, performance, functionality, and quality, both for the system and its dependencies. In addition to anticipating future scalability and coupling requirements, the result was that he improved the portal's performance by 60%. Beto is meticulous, detail-oriented, and always seeks technical excellence; he demands a lot from himself and, consequently, from the team he works with. I highly recommend him for any high-performing team that faces complex challenges and requires someone analytical, methodical, and rigorous.”
“I had the privilege of working with Alberto Moreno at two different companies. In the first, we collaborated on projects to validate new business hypotheses, where he led the front-end with cutting-edge technologies and a clear focus on customer experience. In the second, we jointly developed a B2B platform with a multi-company and multi-user web experience, optimized for high performance. Alberto is a collaborative, adaptable professional with a strong command of methodologies such as Scrum and Extreme Programming, adjusting processes and architecture according to project needs. His combination of technical excellence and user focus makes him a key member for any team.”
