- Took part in the team that developed and maintained Modivcare's main React Native application used by patients and caregivers to schedule non-emergency medical transportation (NEMT).
- Acted as the subject matter expert on web accessibility. Programed accessible applications, advised engineers and designers on Web Content Accessibility Guidelines (WCAG), and explained the Americans with Disabilities Act (ADA) requirements.
- Incepted Modivcare's React Native component library to house components shared by all Modivcare's React Native applications, ensuring a consistent branding that is easily maintained.

Full-stack Developer
Chop Dawg
- Architected and developed web and mobile solutions for clients. Depending on their project size, wants, and needs, I would design React, React Native, AWS, and/or Google Cloud solutions and then implement them.
- Led development teams of 1-5. Besides regular full-stack development, I would also conduct code reviews and mentor junior developers as a lead developer.
- Developed a business-social mobile application that shared electronic business cards. Besides a React Native application, a Content Management System (CMS) portal was also developed in React. All back-end infrastructures were housed in AWS.
- Developed an application that lets users schedule regular donations to nonprofit organizations. Stripe API was heavily utilized to manage transactions and automate the onboarding of nonprofit organizations.
Full-stack Developer
7D Imaging
- Developed a React Native tablet application designed to be an educational tool for medical students learning ultrasound techniques. The app had a heavy dependency on React-Native-video, React-Native-SVG, and React-Native-pdf.
- Developed an authoring tool in React to create time-series data that would supplement ultrasound videos. The app would use this data to overlay SVG points or polygons on top of ultrasound videos and images.
- Architected the AWS infrastructure that both applications would use. The AWS Amplify suite was mainly used.
Experience
Modivcare Care Manager Dashboard
Modivcare Member App
I was one of the full-stack engineers in a team of six that continuously developed and maintained the software. Since ePHI was prevalent, security was a heavy priority to abide by HIPAA regulations.

https://survey.dontgo.travel/Single Sign-On authentication was required and was done so via Auth0. I also developed a dynamic approach to manipulating page meta-data for sharing content-specific Facebook posts.
