Utilizing my skills and creativity to build innovative tech that improves the quality of life of others
Hi, I hope you're doing well! I'm a Computer Engineering major at UIUC graduating May 2023. Previously I've interned at Ameren for two years and at Capital One during summer 2022 as a software developer. Over the past 6 months I've developed a passion for blockchain technology and have since then done a lot of self learning and gained hands-on experience through various blockchain side projects. For example, I created my own NFT collection (https://opensea.io/collection/4rcade) where the tokens aren't just images, but are instead interactive games. I'm most proficient in C++ but the skill I've been honing is the ability to swiftly and effectively learn new frameworks and languages. Because technology changes and evolves quickly I think it is vital to be able to be comfortable with being uncomfortable. Ultimately, I strive to learn as much as I can everyday so that I can apply my knowledge and creativity to build innovative tech! I'm currently looking for a full-time position as a blockchain developer. I live in San Francisco and am able to work in-person as well. Please shoot me an email if you'd like to get in touch!
