About

I am a self-motivated Software Engineer with over six years of experience, specializing in blockchain and frontend development. At Overdose, I worked on a DeFi project built on the Solana blockchain, utilizing Rust for smart contracts and React for the frontend. My responsibilities included developing the frontend application, writing smart contracts in Rust, and contributing to the project architecture. The platform I worked on is a decentralized solution for optimized speed and reduced transaction costs, providing users with innovative and analytical tools for managing digital assets. My technical skills include Rust, Solana, Anchor, React, Redux, Node.js, and AWS. Before working at Overdose, I was a Full Stack Engineer at Mobilunity, where I enhanced a marketing platform's functionality, including live chat, bot builder, and analytics, and developed a mobile chat application for iOS and Android. I have also worked as a Frontend Engineer at barnetPOS, updating and developing a large POS system, and at ArtHouseLabs, developing web and mobile slot games. My experience spans small teams of 2-3 developers to larger teams of 7-10 developers, and I have a strong foundation in functional and reactive programming, OOP, and application architecture patterns like DRY, SOLID, and GRASP. I am passionate about creating high-quality production code and continually improving my skills to tackle new challenges in technology and software development.

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
