About

I am an entrepreneur and internet freedom activist working at the intersection of technology, media, and politics — driven by the conviction that access to information and freedom of expression are foundational to democratic society.

Over two decades I have founded and led Balatarin, a Persian-language social media platform I built from the ground up, and NetFreedom Pioneers and Toosheh, a patented satellite-based content delivery system reaching some of the world’s most censored environments.

I hold a PhD in Physics from MIT and a postdoc in bioinformatics from Stanford, and I work across software product building, nonprofit, academic, and startup contexts.

Balatarin

Balatarin is a leading Persian-language social media platform dedicated to fostering free expression, independent thought, and democratic discourse among Persian-speaking communities worldwide. Founded with the mission to empower voices advocating for democracy and human rights, Balatarin provides a secure digital space where users can share ideas, surface news, and challenge authoritarian narratives.

Through initiatives including a mobile app with an integrated VPN — developed in collaboration with Google Jigsaw — the platform ensures secure access to uncensored content for thousands of users inside Iran. Balatarin also leads projects that promote democratic accountability and counter propaganda, including a comprehensive database of Iranian officials for use by journalists, researchers, and policymakers.

Balatarin was among the earliest production applications built in Ruby on Rails. For several years it ranked in the top 20 most-visited Rails sites in the world. I wrote the first 10,000 lines of code.

Project

Toosheh & NetFreedom Pioneers

NetFreedom Pioneers (NFP) is a nonprofit organization dedicated to advancing internet freedom and enabling secure access to information in regions where censorship and restrictions threaten free expression. NFP uses innovative technologies to break down barriers to connectivity, ensuring that individuals can access critical information and engage with the global digital community.

NFP's flagship project, Toosheh, delivers educational, cultural, and news content via satellite to audiences in highly censored environments — no internet connection required. We designed and patented a new protocol that encrypts data within the MPEG-2 broadcast standard, allowing files to be delivered over satellite and recovered on the ground without detection. The system has been deployed across multiple countries.

Patented technology. Deployed in multiple countries. Coverage in Wired, CNET, and other outlets.
