CTO / Principal Consultant / Lead Python Consultant
About Me
I am Gustavo Alberto Reyes Quiroga, a technology leader and senior software consultant with extensive experience building scalable products and leading engineering teams. My background combines computer systems engineering and business administration, which helps me bridge technical execution with product and business strategy.
I have served as CTO at Tonder, where I helped lead the startup through funding, client growth, and product delivery. In that role, I managed development efforts, improved system performance, strengthened security, and helped define the technical architecture using Python, AWS, React, and related technologies.
As a Principal Consultant at Alluxi LLC, I have worked on a wide range of high-impact projects for clients such as GoDaddy, World Market, Upward, EducarUno, Zequenze LLC, Medulla Inc, and Ad Astra International. My consulting work has focused heavily on Python, Django, Flask, Airflow, AWS, and full-stack development, often in environments that required both technical depth and strong delivery discipline.
I have contributed to large-scale systems such as tax data integration platforms, loyalty rewards applications, mobile finance apps, learning management systems, reporting tools, and calendar modules. Across these projects, I have consistently focused on improving performance, reliability, and user experience while supporting business goals.
My technical strengths include backend development, full-stack engineering, DevOps practices, database design, and cloud-based architecture. I have worked with technologies including Python, JavaScript, React, React Native, Node.js, Django, Vue.js, Angular, Docker, and Ansible, along with multiple relational database systems.
I also bring experience mentoring developers and collaborating across teams to deliver complex solutions. I value clean architecture, practical problem-solving, and building systems that can scale with the needs of the business.
Overall, I am a hands-on engineering leader and consultant who enjoys turning complex requirements into reliable software products. I am especially interested in roles where I can contribute both as a technical expert and as a strategic partner to product and business teams.
