Punching Pixels

https://punchingpixels.us/
A pure HTML JavaScript corporate website. I was the full-stack, front-end developer in charge of creating the website from scratch using wireframes, I developed code for text animations, sliders, scroll effects, parallax effect in images, cursor animations, transitions, and masking interactions.

Diderot

https://www.diderot.one/
I was the React full-stack developer for a top university in Pennsylvania, I helped the current team rewrite part of the application, added a Storybook component library to the project, and developed a scoring guide component used to evaluate the quality of the student's submissions.

Social Coach

Developed a React website with the goal of connecting businesses that want to improve their social media platform's interactivity with coaches that have expertise in the area.

I designed CSS templates for use on all pages of the website. This functioned with the CSS background, positioning, text, border, margin, padding, and table. I used React-Router to turn the application into a single-page application and React JavaScript components, forms, events, keys, router, and animations. I transmitted large blocks of JSON with RESTful web services, created a responsive design, and developed a single isomorphic responsive website that worked on desktop, tablets, and mobile using React. Maintained states in the stores and dispatched the actions using Redux. Created and used reducers that received said actions to modify the store state tree—collaborated with back-end engineers to optimize existing API calls to create efficiencies by deprecating unneeded API calls. Used object-oriented programming concepts to develop UI components that could be reused across the web application. Extensively used Git for version control and regularly pushed the code to GitHub.

Revlimid

https://www.revlimid.com/
Revlimid is a prescription medicine used to treat adults with multiple myeloma. The main goal was to ensure all visuals looked perfect in all devices and browsers; the information shown on the website was highly sensitive, and for that reason, the quality of the code had to be 100%. I worked hand-in-hand with design and development groups to create shared standards and modules from mock-ups and Photoshop. I implemented tools that improved the quality assurance speed by 300%.

Claro SGV

https://www.claro.com.do/
Undertook the development of a promoter sales management system for the biggest communication company in the Dominican Republic. With a team of eight developers, we built a web and mobile app that were the tools used to sell company services with promoters. I was in charge of the front-end development and also provided back-end support.

Picsera

https://www.picsera.com/
Oversaw the development of an online service for clients in need of post-production imagery and a newly improved workflow for generated orders. The project was completed using WordPress and WooCommerce. I developed the WordPress portion, from modifying themes and plugins to adding new functionalities to the web app, including connection with third-parties like Paypal, Zoho, and Dropbox.
