MAP

An all-in-one app revolutionizing goal accomplishment. MAP utilizes a cutting-edge multi-agent technology platform that enables users to conversationally set goals, understand required daily actions, and maintain accountability across all domains of their life. The platform's AI agents work in concert to break down complex goals into manageable steps, adapt to user progress, and provide intelligent, context-aware support throughout the journey.

GPTsForDevs

A TypeScript-based documentation scraper and AI assistant generator for iOS libraries. Built to address the lack of code completion tools in iOS development, it scrapes and sanitizes documentation from multiple iOS libraries to create specialized AI assistants. Each assistant is grounded in library-specific knowledge (SwiftUI, Swift Charts, UIKit, AudioKit, etc.). The project gained over 100k users and significant traction on Reddit by leveraging the ChatGPT Store ecosystem.

Crazy Health Stats

While researching global health and obesity data, I built a real-time visualization of obesity rates by country. The project takes percentage growth estimations from various data sources and applies them to the most populous countries globally, inspired by the US debt clock. Visitors can quickly grasp the scale of the obesity epidemic and see the estimated annual healthcare costs each country faces due to this growing problem.

Kitchen Pal

Coming Soon

A recipe management tool born from the frustration of scattered recipes and cluttered recipe websites. It allows users to paste any recipe URLs and automatically extracts the core recipe information - ingredients, instructions, and serving sizes - while stripping away ads and SEO content. The parsed recipes are transformed into beautiful, clean recipe cards inspired by classic cookbook designs like Barefoot Contessa. Currently in development with planned features including recipe sharing and automated grocery list generation based on weekly meal selections.

Testimonials

Bryan Waterman

CMO at Delivery Dudes

"I've had the pleasure of working with Parker for over five years. In that time, I've witnessed his drive and determination propel him from Freelance Designer to VP of Product here at Delivery Dudes. What I admire most about Parker is that he's both a sponge and a chameleon. I have worked in this industry for many years, and I have never met someone with such a thirst for knowledge and extraordinary talent to pivot and adapt to changing situations. Parker has also invested a great deal of time an energy into understanding what makes a great leader. While he is firm in his beliefs, he always keeps an open mind. It is traits like this that have helped him become the influential and respected leader he is today."

Sam Shapiro

Director of Placements at Insight Global

"I have had the pleasure of working and partnering with Parker for the last two years. Our work consisted of building teams of talented developers and product managers. Parker's ability to evaluate talent and attract talent is second to none. In a market as competitive as it is today it is crucial to be able to access a candidate's strengths, weaknesses, and motivators. But, being able to sell a candidate on his vision why they will be successful in his environment is truly an X-Factor and what separates him from the pack."

Kayle Gishen

VP of Engineering at Delivery Dudes

"Working with Parker was transformative for our engineering culture. His focus on code quality and developer experience set new standards for our team."

With his upbeat personality and unmatched charisma, he has not only led the team to success but also created a friendly and welcoming working environment. I highly recommend Parker Rex and I trust he will continue succeed in all of his future endeavors."
