Now
I'm an engineer with a passion for building innovative solutions that solve real-world problems and make technology more accessible to everyone. With over 8 years of experience in software development, I've worked across multiple verticals and companies including Enterprise Technology, Cloud Computing, Healthcare, Insurance, and Fintech.
Over the past few years, I've been exploring the intersection of web development and emerging blockchain technologies. In my spare time, I enjoy learning about cutting-edge innovations and sharpening my skills by building projects at conferences, hackathons, or simply for fun.
I like to work in an autonomous, free-flowing way — avoiding bureaucratic tape and mundane processes. If something needs to get done, I believe in making it happen efficiently, while keeping communication open and objectives clear.
Projects
Mastercard Design System I helped pioneer over the past couple years - everything from components, to design tokens, to client branding.
One of the core products I built at Mastercard. A web and mobile app that allows users to manage their corporate credit cards, approval workflows, enrich transactions, and more.
Chatbot that answers any and all questions about one of my favorite artists, Olafur Arnalds. Built with NextJS, LlamaIndex, and AstraDB.
Generate digital signatures via Google Auth with Lit Protocol, a decentralized key management network.
Building

In the initial stages of building an agentic property management platform. Stay tuned!
