Hi, I'm Ivan Figueroa πŸ‘‹

MSCS @ Florida International University (2026) | Full Stack Software Engineer Intern @ Sports Excitement | ShellHacks 2025 2nd Place (Google AI for Social Good)

LinkedIn β€’ GitHub


πŸš€ About Me

I enjoy software development and using technology to improve our lives.

I’ve previously interned at Sports Excitement as a Full Stack Developer Intern, where I worked with product managers and engineers in Agile Scrum methodology for the company’s sports gear marketplace platform.

I also deployed LoyalPass, a loyalty platform aimed for small businesses that lets merchants create custom reward programs with Apple and Google Wallet passes.

Most recently, I developed EzSpeak, a Chrome extension meant for online web meetings that won 2nd place at ShellHacks 2025 (Google AI for Social Good Challenge) by providing real-time captions, translations, and AI voice for inclusive communication.
