About

Eduardo Salinas

Software engineer with 4+ years building systems at the architecture level. I specialize in backend and cloud — distributed systems, microservices, and infrastructure. I adapt quickly to new contexts, enjoy leading teams, and I'm always looking to learn something new.

I thrive on complex collaborative projects, helping the people around me grow, and staying sharp on what's happening in the ecosystem. I believe great software is built as a team — with clear thinking and a real drive to do things right.

TalentLand Hackathon Micron 2025

Guadalajara, Mexico

I had the privilege of participating in the prestigious TalentLand 2025 hackathon, where I collaborated with an exceptional team on a challenging project for Micron. Our innovative solution involved developing an algorithm that helped optimize and reduce losses in their semiconductor operation and production flow. We implemented comprehensive data analysis using Micron's proprietary technologies, while also automating notifications and data personalization between different company teams using Power Automate. This experience not only enriched my professional profile but also allowed me to establish valuable connections in the industry.

Mobility Hackathon Aguascalientes 2025

Aguascalientes, Mexico

I had the honor of participating with my incredible team in the Mobility Hackathon Aguascalientes 2025, organized by the General Coordination of Mobility, the Aguascalientes Institute of Education, and the Technological University of Aguascalientes. Our project 'YoVoy en Ruta' focused on improving the experience of public transport operators, and we managed to obtain second place in Vertical 1: Human Capital. We developed a platform where public transport drivers could receive feedback and, based on their ratings, earn benefits within their job. Additionally, by having user participation, we helped drivers perform better and enjoy their work, which would reduce the initial problem of high turnover rates in the sector.

Hackathon Project Presentation

Aguascalientes, Mexico

We attended a technology conference in the state of Aguascalientes where we presented our hackathon project to the state governor. The project was a system designed to assist 911 calls, featuring an agent that listened to the call and instantly collected information, notifying the necessary services and making the process flow faster without replacing the operator but serving as a tool to streamline the process.
