I'm a full stack mobile engineer with 11+ years of experience, and I've had the chance to work across a variety of industries like live streaming, healthcare, fintech, web3, sports, and SDK development. Whether leading a team or flying solo as the go-to engineer, I've built apps and tools that not only solve problems but also make users' lives easier. I've worked at both startups and large companies, so I'm comfortable wearing many hats or diving deep into technical challenges. From launching apps used by millions to creating SDKs for global partners, I always focus on writing clean, maintainable code and building great user experiences. I also enjoy collaborating across teams to make sure products meet both technical needs and business goals. I’ve also gotten plenty of experience as a founder, working on my AI conversational platform: convo.ai. I'd love the chance to bring my experience and passion for mobile development to any team.
