Bridging Complex Systems &
& Scalable Solutions.

My name is Lewis Garcia. My journey in programming began in my childhood with C++. Today, I specialize in architecting and developing complex integration solutions and SaaS platforms.

I graduated with honors as a Computer Engineer and currently share my expertise as an Adjunct Professor at Universidad de Oriente. I am passionate about transforming technical challenges into elegant, robust software solutions.

My most ambitious projects include a high-performance flight booking platform that unifies providers with different processes, and IoT control systems for the oil and gas industry.
