Ruby on Rails Expert | Real Time App | NodeJS | ReactJS | NextJS

As a developer with over 7 years of experience, my journey began with a curiosity for how technology can be harnessed to solve real-world problems. Early on, I was drawn to full-stack development because of the opportunity to work across the entire application lifecycle. My expertise lies in Ruby on Rails, ReactJS, and React Native, but my passion for learning has driven me to continually expand my skill set with technologies like GO, NextJS, Node.js, and Python. One of my recent accomplishments was leading the development of a mobile app that streamlined a complex insurance process. By integrating APIs, building a custom voucher system, and enhancing the user interface, I not only improved the user experience but also contributed to a 10% increase in sales. This project reinforced my belief in the power of well-crafted software to drive business success. What sets me apart as a developer is my focus on problem-solving and scalability. I thrive on dissecting complex issues, whether it's improving performance by optimizing code or implementing a solution that scales seamlessly. I’m passionate about helping businesses grow through technology, and I pride myself on my ability to adapt quickly, learn new tools, and apply them to solve unique challenges. Above all, I am committed to building high-quality, impactful software that not only meets the needs of users but also drives meaningful results for the businesses I collaborate with. Whether it’s developing from scratch, maintaining existing projects, or testing new ideas with an MVP, I bring a versatile and solutions-driven mindset to every challenge.

I honed my skills in Ruby on Rails early on, and I'm particularly proud of my commitment to quality, like when I took untested production apps to 95% code coverage. This foundation as a developer deeply informs my leadership approach, giving me a strong understanding of the challenges and opportunities my teams face. A recent highlight includes my time as CTO at Sonatafy, where I developed AI screening to improve hiring and recruiting efficiency.   Building and scaling teams is a passion of mine, demonstrated by my experiences at Spring Health and Freshly, where I rapidly expanded engineering teams while maintaining a focus on delivery and quality. I excel at connecting technology with business strategy, and I have a proven track record of driving key business metrics and reducing costs through innovative solutions. For example, I owned the engineering of an internal EHR at Spring Health, which decreased expenditures in the tens of millions annually.   My unique skills lie in the blend of my technical expertise, strategic thinking, and leadership capabilities. I'm adept at system architecture, project management, and IT strategy, with a focus on fostering collaboration and enhancing operational efficiency. I believe in investing in people, and I am committed to mentoring, training, and guiding teams, even through complex transitions like the billion-dollar acquisition I navigated at Freshly.
