Frank D’Angelo

Senior Software Engineer

I build large scale, web and mobile applications.

About

I launched my software development career doing freelance work starting in 2018, before completing an intensive 800-hour Full Stack Web Development program at Flatiron School in 2020, which deepened my expertise in coding and web development. Since then, I’ve advanced through roles at Computer SOS, Mean GuppyPopmenu, and Women Who Code. As a Senior Software Engineer, I focus on enhancing web applications and have been instrumental in roles that demanded both technical finesse and leadership skills. I’m also the CTO and co-founder of Heart 2 Heart, an innovative audio and video dating app designed from scratch to offer a unique, interactive dating experience without the need for swiping or text-based messaging.

My expertise lies in crafting high-performance software solutions with a strong focus on React, TypeScript, and Ruby on Rails. I’m passionate about building accessible and efficient user interfaces, particularly those that bridge the gap between design and technical excellence. Beyond my routine, I’ve contributed to the tech community by developing innovative features like AI-driven social post suggestions and integrating complex data analytics systems.

When I’m not coding, you’ll likely find me hitting the trails or staying active with bodybuilding—it’s how I recharge. I’m also a big tech enthusiast, always keeping up with the latest gadgets and electronics, and I have a special spot for anything Apple. Whether I’m tweaking code or pushing my limits at the gym, I’m all about embracing challenges that sharpen my skills and expand my perspectives.
