Ono Saburo

O Ono Saburo Tokyo, Japan -- As a Senior Front-End Developer, I leverage my React & React Native expertise to create engaging and accessible mobile applications for millions of customers. I have 8+ years of proven experience in web & mobile development. I have a druid level understanding of software. Ive worked solo and on team-based projects with JavaScript, TypeScript, React.js, Redux, Node.js, Python, .Net Framework, React Native and Swift with a background in databases. I describe myself as detail oriented, highly technical and I thoroughly enjoy devising innovative and tailored solutions to meet the ever-changing business requirements for clients. In general, I love deploying my mad skills for those that hire me. I have a rare ability to not only be technically masterful at the work, but also to be able to anticipate what needs exist within a module and on the user end of things. So, I’m more than just technical. There are a LOT of programmers out there that only know how to follow a single line of thinking. WAY TOO linear. Our brains are MASSIVELY PARALLEL so why shouldn’t software projects be developed in the same way? Don’t you think? Also, I am a quick learner and am always looking for the next challenge. I thrive on it. Work Experience Mobile Developer 03/2014 to 05/2015 Legato LLC United States Social network app. Lead developing new features.
