About Me

Since building my first website in 2010, I’ve had a burning passion for web development, which has evolved to include digital marketing and, most recently, artificial intelligence. I help companies navigate the interplay of these three.

I can build systems from scratch, optimize what’s already there, or simply give my professional opinion on solving any web development, digital marketing, or AI-related problem.

I’ve worked full-time remotely for over 13 years with clients from both America and Europe. No matter the time difference, I pride myself on getting the work done on time and mesh seamlessly with any team that values effective communication.

My roles as lead developer, web consultant, and advisor to companies in many different fields has helped me to think on my feet and solve problems fast. That's why I thrive in fast-paced environments with tight deadlines and high expectations.

Work Experience

Over the years I’ve had the pleasure to work with some truly great companies and clients.

Too Pixel

Too Pixel was a traditional web design agency in Geneva, Switzerland, focused on providing custom-built solutions for their clients. After becoming one of their first hires, I was soon promoted to the lead developer role and managed projects for brands including: CERN, Notz Stucki, EPFL, Newby of London, and much more.

My 7 years working full-time remotely for Too Pixel helped me master my core skill of web development. The traditional agency atmosphere also helped me learn how to work effectively as part of a team with high-stakes projects on the line. I had to pitch ideas, implement feedback, and shift gears quickly when plans had to change.

Single Grain

Since 2009, Single Grain has been a well-regarded digital marketing agency with clients like Uber, Amazon, Lyft, SalesForce, and AirBnB. I was first hired to manage all the web properties of the company and report directly to the CEO, Eric Siu, known best for his Marketing School podcast with Neil Patel.

My core expertise at the time was web development, but being surrounded by highly skilled marketers, I quickly learned a lot more about digital marketing. I was soon invited to join the internal Growth Team, responsible for scaling Eric’s personal brand and new business ventures. These projects were built in a ‘lean startup’ mentality, requiring me to learn new skills fast, and find solutions to problems working with limited resources.

In line with the evolving technological landscape, I am currently at the helm of our artificial intelligence transformation initiatives. Both within Single Grain and for our diverse roster of clients, I am spearheading the integration of AI into our existing workflows and service offerings.

Generation Genius

Generation Genius is a Los Angeles-based startup building an educational streaming service teaching kids about science & math, while also offering a range of home science kits for hands-on exploration.

As the first full-time developer hired, my core responsibilities encompassed enhancing the website, designing and implementing new features, as well as addressing issues within the legacy systems. In my 2 years leading the development growth scaled from 250K to 1.25M visitors per month along with a 6X increase in revenue. After this successful period, I transitioned to the role of a consulting developer. My responsibilities include strategic decision-making, assisting with developer recruitment, and resolving critical issues.

Generation Genius, now not only ranked the #1 Fastest Growing Education Company in America on the 2022 Inc5000 list due to a staggering revenue growth rate of 4,891% from 2018 to 2021, has also garnered the tremendous honor of being named to TIME Magazine's list of 100 Most Influential Companies in the World for 2023. This prestigious recognition has us sharing the list with household names such as Apple, SpaceX, OpenAI, and Nvidia.

Hire Me on Codeable

After a careful vetting process which included a professional review, technical exam, behavioral interview and live coding test, I was accepted into Codeable in 2017 to offer my services on their premium marketplace. Since then, I’ve completed over 130 projects for 46 clients, with a verified user rating of 4.96 out of 5 stars.
