Hi! I'm

Iglesias
a Software Engineer
I'm Sebastián Alejo Iglesias, a software engineer and teacher based in Argentina, who speaks English and Spanish. I've been working in the tech industry for over 9 years, and I've had the opportunity to work for both big tech companies and startups. I'm a full stack engineer, and I'm proficient in a variety of languages and technologies, including Java, Scala, Typescript, and React. I'm passionate about building innovative and user-friendly software. I'm also a lifelong learner, and I'm always eager to learn new things. In my free time, I enjoy testing machine learning tools, 3D printing, ham radio, hydroponics, soccer, gaming, and traveling. My goal is to be happy with myself and with my work. I hope to one day start my own company, but I'm unsure as to what that company will do. For now, I'm focused on learning and growing as a software engineer.

Laboratory I & II (3rd-year students): This course provides the fundamental knowledge required to develop a software project, covering all stages from conception to implementation and testing. Students work in groups and propose real-life software projects, using use case analysis to define requirements and create an implementation schedule. The course evaluates progress through two partial deliveries, where each group showcases their use case implementations using the developed software.
