What I'm looking for

I seek a dynamic role where I can leverage my full-stack development skills, work collaboratively in Agile teams, and contribute to innovative projects.

I am a seasoned full-stack developer with extensive experience in Ruby on Rails and C#. My journey began with a Master’s degree in Computer Engineering from the University of California, Santa Cruz, and has evolved into a robust career where I have successfully led and contributed to numerous projects utilizing Secure Software Development Life Cycle (SDLC) principles.

Throughout my career, I have held key positions such as Senior Ruby Developer at Notif.ly, Inc., where I managed existing repositories and led teams in adapting Agile methodologies. My recent projects include developing a FinanceApp in C# .NET 9.0 and a WhatsAppClone using Java and Angular. I am passionate about implementing best practices and fostering collaboration within teams to deliver high-quality software solutions.
