I believe in the power of the internet and it's ability to connect. Being essentially plugged in since birth, and given the opportunity to experience this gift of communication, knowledge, and looks into other worlds - I'm very grateful to have an opportunity to contribute to it through web development. Although money is nice, I didn't teach myself full-stack development just to earn it - I'm also passionate about seeing your idea come to life. Over the years, I have become experienced in the ins and outs of UI Design, APIs, Javascript, React, and Node.js. In all of this though, I want to help make other people's ideas be the best that they can possibly be. If you like the work I do for you, please leave a positive review! :) Feel free to book a consultation, or message me to get my email!

Post-college graduation in 2011 I set out to build an app to connect people based on their activity interests. This became a collection of mobile apps called, Fitivity and Elete Dribble Training. I was fortunate to be a part of a team that raised $1.5 million in funding utilized to further grow the company. The backbone of this success was content for users to consume, learn, and practice in their quest for coaching and training themselves in the world of sports and fitness. I like to refer my baseline experience as being thrown into a "lion's den" of UX/UI design and development. I knew nothing back then. As a company, we applied an insane amount of app store search engine optimization testing. Split testing and monitoring metrics was our boon. Organically, we were able to get nearly 10,000 downloads and nearly 100,000 impressions per day at our peak. This opportunity I had, to live in a never-ending UX/UI testing environment, gave birth to a skill set that I took to the E-Commerce world. It fostered the beginning of my marketing career and is the journey that has allowed me to grow professionally in the marketing field. Now, with 10 years of marketing experience, I am confident in my ability to support your business with any conversion rate optimization strategy for your E-Commerce store. Your time is valuable, and the decisions you make now will impact the next chapters in your business. I look forward to connecting with you and discussing the right steps for you and your growing business.
