This is Oscar Kevin’s Personal Website!


Hi! My name is Oscar Kevin Sandoval Rivera 🇸🇻🇺🇸, and I like to work on software that authentically connects and deepens the bonds between current strangers and future friends.

I currently work as a Senior Associate Software Engineer at Capital One and am looking to transition into a full-time web3 role.

I also am bootstrapping Atemosta, a not-for-profit focused on bridging the gap between our physical and digital personas using emerging technologies, notably XR, Blockchain, and Storytelling.

Roadmap: Coming soon…

Sword Art Online on Blockchain! A fan made game where players are trapped on blockchain and must level up to fight and escape back to the real world.




Probably my pride and joy, a simple project I spun up in college and have slowly been improving as I learn more within and outside my job. It serves alerts to over 3,400 twitter users and 150 discord users, and has ran without major issues since 2017! Currently refactoring into a microservices architecture with complete CI/CD.
