The question is never ”can it be done?”

The question is ”is it worth the time?”

Work Experience

NeuralWorks

Fullstack Engineer

Apr 2024 - Present

Pucón, Chile

NeuralWorks is consulting firm that support LATAM Airlines, here I played a key role in enhancing and scaling the company’s AI-driven experimentation platform. Given my strong front-end expertise, I was responsible for refactoring and optimizing critical parts of the platform, improving performance, usability, and maintainability.

I led the development of a custom dashboard that provided real-time analytics and insights into experiments, significantly improving the way users interacted with and interpreted AI-driven results. To ensure scalability, I introduced structured testing practices and helped implement a more reliable deployment process, reducing system downtime and improving developer efficiency.

Beyond coding, I worked closely with product and leadership teams, aligning technical improvements with business goals. My contributions helped increase platform adoption and streamline experimentation processes, ultimately enabling more effective decision-making across LATAM.

Blissway

Frontend Engineer

Apr 2022 - Dec 2022

Denver, Colorado, USA

Upon joining Bissway, I was tasked with rapidly developing a platform to visualize vehicle detections captured by our highway hardware towers. While most trips were accurately reconstructed using AI, around 15% remained unreliable, making manual verification necessary. Accessing raw data in an Amazon S3 bucket was not scalable, so I built a web platform to streamline this process.

Through multiple iterations, I expanded the platform’s capabilities, adding trip deletion, reassembly, validation, and in-app JSON manipulation, enabling efficient data management within the web interface. As the platform scaled, I encountered localStorage limitations and devised a data compression solution, increasing storage capacity 100x, ensuring smooth handling of large datasets without performance degradation. At the end of the test-run, our platform successfully demonstrated its value, leading to securing a contract with the Colorado Department of Transportation.

As the first frontend engineer at Pinflag, I was responsible for setting up the entire frontend architecture, selecting technologies, and establishing best practices.

I led the hiring and management of a 3-person team, ensuring smooth collaboration and development efficiency.\nI spearheaded the development of Pinflag’s main platform from scratch, working closely with a designer to iteratively refine the user experience and product vision. Later, I laid the foundation for the mobile app and developed an interactive iframe application leveraging Mapbox, which visualized over 800 points across Chile in an engaging and dynamic way.
