Experience
The Transmillenio Project
I created a ticketing solution developed for Ipsidy/Transmillenio, effectively replacing 500+ cashiers across 800+ ATMs. My contribution included both the architectural design and the actual implementation of the solution. The impact of this implementation was significant, as Transmillenio now saves thousands of dollars monthly.
The ticketing solution I developed was tailored to the specific needs of Transmillenio and provided a seamless, user-friendly experience for their customers. Through careful analysis of their existing system, I was able to design an architecture that maximized efficiency and minimized costs. The solution allowed for real-time tracking of transactions, eliminating the need for manual intervention and oversight.
The successful implementation of this solution had a profound impact on Transmillenio's bottom line, as they drastically reduced their labor costs. Eliminating over 500 cashiers resulted in significant savings, which continue to accrue monthly. Furthermore, implementing the ticketing solution improved the overall efficiency of Transmillenio's operations, providing their customers with a more convenient and streamlined experience.

Face Recognition-based Access Solution for Universal Studios
I created a face recognition-based access solution developed for Ipsidy/Universal Studios. The solution eliminated the traditional ticket-checking system and provided guests with a seamless, frictionless experience. My contribution to the project included both the architectural solution and a working prototype.
Through carefully analyzing Universal Studios' existing access control system, I could design an architecture seamlessly integrated with its existing infrastructure. The solution I developed utilized advanced facial recognition technology to quickly and accurately identify guests, eliminating the need for manual ticket checks.
In addition to the architectural solution, I also developed a working prototype that was rigorously tested to ensure its reliability and accuracy. The prototype handled a high volume of guests while maintaining a fast and efficient throughput.
By eliminating the traditional ticket-checking system, Universal Studios was able to greatly reduce its labor costs and improve the overall experience for its guests. Guests could enter the park quickly and easily without needing a physical ticket or manual checks.

Iris Recognition-based Control System
I was involved in designing and implementing an iris recognition-based control system for Ipsidy and several security companies in Bogota, Colombia. This solution completely transformed their security operations, leading to substantial monthly savings of thousands of dollars. My contribution encompassed the entire solution design as well as the implementation.
The system utilized advanced iris recognition technology to replace the need for traditional access control methods, such as smart cards (SC). By carefully analyzing the security companies' requirements and infrastructure, I developed an innovative architecture seamlessly integrated with their existing systems. This architecture allowed for real-time identification and verification of individuals through iris recognition, eliminating the need for SC hardware support and SC issuing.
Rigorous testing and quality assurance measures were carried out to guarantee the system's reliability and accuracy. As a result, the security companies experienced a seamless transition to the iris recognition-based control system.
