Summary

I am a Systems Engineer with 9 years of experience in the software lifecycle, working with C#, .NET, Java, and BPM process flows using Bizagi. I have developed web, mobile, and desktop applications, handling both front-end and back-end, with business logic as my main strength.

Thanks to my specialization in Enterprise Architecture, I understand businesses from both a functional and non-functional perspective, which allows me to propose comprehensive solutions aligned with organizational goals. I have experience in SOAP and REST service integration, SQL database management, and web technologies such as JavaScript, HTML, and CSS.

I excel in software analysis and design, incident resolution and deep problem analysis, team leadership, and effort/resource estimation. I work under the SCRUM methodology, ensuring high-quality and results-oriented deliveries.
