    Hi, I'm an expert full-stack web developer based in Columbus, Ohio, with over 9 years of professional experience building great websites. I specialize in crafting responsive, high-performance websites and applications that are not only visually engaging but also fully accessible and optimized for top search engine rankings. Over the years, I have worked on a wide range of projects—from creating websites for schools and companies to developing custom Content Management Systems complete with robust databases. Whether it's designing intuitive online forms, implementing ADA compliance features, or boosting a site's SEO, I ensure that every project I tackle is built with both the end-user and business goals in mind. My technical skill set spans a broad spectrum of technologies, including ASP.Net, HTML, JavaScript, CSS, Node, SQL Server, MySQL, PHP, C#, WordPress, Shopify, and modern frameworks like React and Next.js. This diverse expertise allows me to deliver tailor-made solutions that meet each client's unique needs. From 2016 to 2021, I served as a full-stack developer at EMS Linq, where I played a key role in developing websites and online forms for educational institutions. I was deeply involved in everything from database management to integrating custom analytics directly into our CMS. Since 2018, I’ve been freelancing, collaborating with various companies—some using WordPress or Shopify, while others required custom solutions built with React, ASP.Net, or plain HTML, JavaScript, and CSS. When I’m not coding, I love to push the boundaries of creativity. I enjoy developing fun applications and games for friends and family, and I've even built a neural network in JavaScript that can solve mazes, play games, and generate abstract art. Additionally, I volunteer as a math GED tutor, helping others overcome challenges and achieve their academic goals. If you’re looking for a dedicated, innovative developer who can transform your digital vision into reality while ensuring accessibility and peak performance, let’s connect. I'm here to help you create an outstanding online presence that drives results.

    Highly skilled and accomplished Software Engineer with a proven track record of success in designing, developing, and implementing complex software solutions. Bringing over 9 years of full-stack experience in the software development lifecycle, I excel in both frontend and backend technologies, focusing on creating secure systems. I am known for my problem-solving abilities, teamwork skills, rising to challenges, and exceeding expectations. I am confident in my ability to step into the role of a Senior or Lead Software Engineer. While the majority of my experience has been in Java and financial technology, I am currently interested in expanding my experience and skill set to include cybersecurity, data engineering, and machine learning. To that end, I am using multiple self-paced learning strategies to learn Python, refresh my SQL skills, and generally improve my craft. These strategies include websites such as HackerRank, Brilliant, Codility, and Execute Program. I am also working on two personal projects in Python. Throughout my career, I have demonstrated an ability to rise to challenges. In my first year at Chase, I took on fixing a reporting system that had been broken during a tech refresh, and I was able to not only fix the issue but improve the system based on user feedback. Not long after, I was given the task of fixing the hundreds of issues identified by a security scan report, and I built my own tools to organize the issues to communicate with management about the priorities. I not only fixed many of the issues myself but also organized the effort to make sure it was completed, found many of the fixes I did not implement, and eventually became the application security champion, calling out potential issues during code reviews. For both of these, there were no existing subject matter experts on the team, so I had to learn on my own and become that expert. Most recently, in my position at Focused Labs, I stepped up to organize efforts around a major refactor in one of our applications, became the expert on a complicated timeline page in another, and took on the responsibility of point contact with the client of a third application. This last included communicating that changes to this app were not the current priority for our team, but I was still able to keep the client happy by agreeing to take on a small amount of work that would help them increase sales by offering a promo code.
