About Me

Since building my first website back in 2004 I’ve had a burning passion for web development, and more recently, conversion rate optimization. Nothing excites me more than delivering work that generates leads & sales reliably on autopilot, helping to free up my client’s valuable time.

I help companies ensure their websites, funnels, ads, email marketing, and analytics work seamlessly together. I can build these systems from scratch, optimize what’s already there, or simply give my professional opinion on how to solve any business or web-related problem.

I’ve worked full-time remotely for over 12 years with clients from both America and Europe. I’m based in Lithuania but no matter the time difference, I pride myself on getting the work done on time and mesh seamlessly with any team that values great 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 unlike a lot of other developers, 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 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.

Generation Genius

Generation Genius is a Los Angeles based startup building an educational streaming service teaching kids about science & math. During the early phase of the company’s growth I was invited to join as their first full-time web developer.

I led a campaign to overhaul all the legacy systems they had in place. I implemented new features to the website, fixed numerous long-standing bugs, and created an easy way to run & analyze split tests. In my 2 years leading the development growth scaled from 250K to 1.25M visitors per month along with a 6X increase in revenue.

Generation Genius has been ranked the #1 Fastest Growing Education Company in America on the 2022 Inc5000 list based on an exceptional revenue growth rate of 4,891% from 2018 to 2021.

Single Grain

Since 2009, Single Grain has been one of the world’s leading digital marketing agencies, 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 award-winning marketers, I quickly learned a lot more about digital marketing and conversion rate optimization (CRO). 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.

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.
