Backend Engineer (Java Spring + Web Scraping) Leonardo was a big help in the time we were able to work with him. He was communicative and available even with 4 hour time zone differences. Would welcome him back!

Project: Migration and Deployment of WordPress (Divi) Site on AWS (Serverless Architecture) Leonardo fue muy profesional, siempre respondió a tiempo y mostró gran paciencia durante las demoras.
El proyecto se canceló por decisión de nuestro cliente final, totalmente fuera del control de Leonardo o del nuestro.
