Experience

Niuko Consultores

Consultant

2022 - Actual

I design and implement technological solutions aimed at improving operational efficiency and streamlining business processes. I have developed and currently manage a dashboard for activity tracking and an internal evaluation system, both of which have significantly enhanced organizational oversight. I lead the design, development, and maintenance of the company’s website, corporate blog, and a support chatbot to improve client communication. Additionally, I have automated key workflows, such as the email distribution of news and updates to clients, reducing manual effort and improving delivery times. My responsibilities also include comprehensive IT support, covering infrastructure management, Windows Server administration, network configuration, and equipment maintenance. I actively contribute to the daily operations of one of the company’s branches, ensuring the seamless integration of technology in its processes. Currently, I am pursuing a Master’s degree in Engineering with a focus on Data Science, which allows me to integrate advanced analytics and problem-solving techniques into my work. This combination of hands-on development, IT administration, and continuous learning reflects my strong commitment to innovation and long-term organizational growth.
Carls Jr.

Supervisor

2019 - 2022

My experience as a Supervisor at Carl’s Jr. was a foundational stage in my professional development, where I refined essential soft and operational skills that directly support my current role in the tech industry. Managing daily operations, handling inventory, overseeing accounts, and ensuring accurate reporting taught me the importance of organization, attention to detail, and process optimization—principles that I now apply when designing and deploying software solutions. Leading a team and interacting daily with customers strengthened my communication, conflict resolution, and decision-making skills, which are critical when collaborating with clients or cross-functional teams in IT projects. This hands-on administrative and operational background has given me a broader business perspective, enabling me to create more efficient and user-oriented technological tools.
