Senior Frontend / Full-Stack Developer

Jupiter St. John

Senior Full-Stack Developer / Senior App Developer

Overview

My introduction to Computer Science began with Linux Systems Administration and Network Penetration Testing. For the past 12+ years I have focused on designing and building: web / web-app, iOS / Android app experiences.

After years of working for clients like Warner Bros, 7-11 and St. Regis Hotels, I have the experience to ensure any project meets with success. I excel with popular Javascript frameworks including React, React Native, Next.js and Angular. Μuch of my recent years have been filled with leading teams of developers (including offshore / overseas developers) to achieve and deliver excellence. I have a unique inner drive that allows me to succeed with anything I put my mind to.

With my combined knowledge of development, creating scalable architecture, specialization in responsive design ( designing for mobile, tablet, desktop to create the best possible experience on each device ), and my attention to UX / UI, I will create the best possible experience to bring your vision to life.
