Matrix Industries Power Watch

https://www.matrixindustries.com
At Matrix Industries, I built two responsive websites. One is an amazing product (a watch that is powered by your body heat) launch website, and the other was needed for the project fundraising. My role was to implement the design, custom widgets, custom business logic, and some integrations (Mailchimp and referrals). The most amazing things I did over there were:

• 360-degree product animation on scroll (product overview section)
• Custom slider on scroll with document hold on mouseover (customize section)
• Custom chart for funds raised (crowdfunding section)
• Custom progress of the referral program (on the referral page)

The design was done by my colleague Serge Zuev (one of the best designers I've ever met).

nScreenAds

As a key developer for the nScreenAds platform, I contributed to both server-side and front-end components, collaborating closely with another developer to create a robust online advertising platform. Leveraging technologies like .NET Core, jQuery, Unobtrusive Ajax, Bootstrap, CSS, Web API, MVC, PostgreSQL, TFS, and Jira, we developed an integrated system that facilitated seamless API interactions with various advertising platforms. My role was pivotal in implementing functionality to aggregate bid data in real time from an S3 bucket, ensuring timely data availability for decision-making processes. The platform we developed empowered users to create and fine-tune advertising campaigns with precision, offering targeting capabilities akin to those found in Google Adwords. This project not only challenged me to apply and expand my full-stack development skills but also provided valuable experience in handling large-scale data and creating user-centric solutions in the competitive advertising technology sector.
