About Me

In college, I realized the impact that technology can have and started a company called Afterclass, a platform for peer-to-peer collaboration built on HTML5, CSS and JavaScript, to target the issue of students not communicating in large classrooms. After graduating the University of Maryland, I began working for Maalka; an open, energy efficiency platform designed to help cities and building owners easily meet their commercial benchmarking goals. At Maalka, I collaborated with the Department of Energy’s National Renewable Energy Laboratory (NREL) in creating an application that allowed users to experiment with different energy-saving building upgrades to determine percent savings which secured $1 million for Maalka. At Maalka, I worked on the next generation interface of the Maalka platform using React, employing cutting edge technology such as Apollo GraphQL, to allow for user-driven data fetching, composable functions, to create reusable libraries, as well as Semantic UI React to quickly build and deploy components. After gaining experience at Maalka I realized it was the right time to fulfill one of my life long dreams, to move to Israel. In February of 2020 I made that a reality and made Aliyah. After making Aliyah I joined the Ulpan at Kibbutz SDE Eliyahu where I both lived, learned Hebrew and worked for 10 months. After the program finished, I moved to Ramat Gan and have started the process of searching for an exciting career as a software developer in Israel. Here is a comprehensive list of the technologies and frameworks I have worked with in the past. JavaScript, Python, Java, React.js, AngularJS, Apollo GraphQL, MongoDB, Node.js, Docker, Redis, Express, jQuery, Android Studio, Java, EJS, HTML, CSS, Lodash, Highcharts, Handsontable, Semantic UI react, React Bootstrap, Material Design.
