Hello, I'm Kalvin. I'm a full-stack/blockchain developer with 6 years of experience based in Austin, Texas.

About me

I enjoy utilizing full stack, blockchain and cloud technologies to automate/implement secure and elastic cloud environments in an agnostic manner. Whether its for small startups, public entities, or large scale companies. My goals are to allow developers to innovate, deploy faster, and create more secure applications.

I have a B.S. from Texas State University along with a coding cerfication from the University of Texas, and have been in the industry for over 6 years. Additionally I hold two AWS certifications and am currently working on obtaining an AWS Cloud Architect certification. Currently I work as a full stack blockchain engineer at Project Venkman where I get to create impactful and cost saving blockchain applications for a variety of clients including public entities.
