Performed code reviews before merging pull requests on Github and manually tested products before submitting them to the client which reduced client complaints and bugs by 25% Integrated Xero API into EYVO’s dashboard using Laravel/PHP to get vendor statuses and logsRoles:- DevelopmentGenerally I worked on business SAAS applications for two companies in Houston. Mostly I designed their layouts and looked over them to find bugs. For bigger projects I worked on connecting APIs or designing projects from scratch using a combination of planning with Sketch and implementing with a team using the Laravel PHP framework.- Project ManagementWhile managing I communicated what tasks need completion with our developers in India. In the mornings I formed scrum meetings to track progress on our projects. By tracking our team's progress I ensured deadlines were being met. I also demoed to clients their applications and updated them on our progress keeping them informed.- DesignWith my Adobe software (Photoshop, Premiere Pro, XD) and Sketch experience, I designed mockups for new projects or feature requests. After completing a design I explained them to the team showing key features and how they should function.
