Energy and Stuff

Implemented the landing page for the Institute for Integrated Economic Research.

An estimate of the energy consumption is displayed at the bottom right corner to raise awareness. At the same time, an array of additional settings can be adjusted on mouseover.
Worked with the Addy team as a lead front-end engineer in two phases. We redesigned and restructured their UI in the first phase while maintaining legacy features wherever required. In the second phase, we rewrote everything in react to make the app more performant and easier to maintain.

Uplyft Capital
Created the new website for Uplyft Capital, a site heavy on animations and view effects.

Animations are imported and managed in a custom interface created explicitly for Lottie and Bodymovin JSON files exported directly from Adobe After Effects.

Forms can be created and edited via a custom interface designed to connect to third-party software via API calls or plain HTTP requests.

The website uses the latest version of WordPress. All the templates are seamlessly split into blocks managed via Gutenberg.

All of the above play essential roles in eliminating the need for development when clients want to launch new pages or modify their branding.


Working closely together with the client, I Implemented a highly customizable WordPress theme heavy in animation effects based on their directions white, maintaining the performance and SEO required for them to smoothly onboard new clients from their portfolio website.

Co-founded is a web application that uses public blockchains to timestamp your original digital creations. Ever since our launch in early 2015, we've collaborated with companies in variours sectors such as: media, medical, research and more.

Mozaik Blog
While employed at Mozaik, I had the honor of implementing the WordPress theme for their official blog.

The fully optimized blogging theme uses several advanced optimization techniques that ensure fast loading and navigation between pages.

Barclays UI for Creating Shows to Be Displayed in NYC Headquarters Exterior Screen
Transformed wireframes to material design-styled UI using Vue and Vuetify to achieve an intuitive user experience.

The project consists of many inputs, complex validations, and a live preview for scaling and positioning assets on the screen. My main focus during development was the reusability of components.

Conduent Innovation Center Tablet Web Applications
For Conduent's Innovation Center, I used Vue, Vuex, and Vuetify to create four web applications to be loaded in native iPad application web views.

The apps control various aspects of the state-of-the-art facility via WebSockets and REST API calls; for example, PDF and video presentation controls, conference calls, etc.

Chobani Gimmies

For Chobani's launch of a new children's yogurt product line, I used Vue to create a live contest website. Contentful CMS manages the application, and the data is updated automatically without needing a browser refresh.

The site used a synchronized timer during the competition, and the opening and closing dates were scheduled beforehand.

Typically, contest submissions would close only seconds after their start, and the app could handle the heavy traffic.
