Vinny-G | Slack-Bot App

Branding + Website + Slack App
HTML5 + Video Animations
- - - - - - - - - - - - - - - - - - - - - - -

Vinny-G was a really exciting project, it’s a Slack bot that allows users to make a pizza delivery request via directly the Slack app!

I designed the branding, the website, and the application platform. I was asked to create a character as the principal icon of the product. After defining the logotype and the branding concept (colors, textures, graphics), I designed the different social network images (Twitter, YouTube, Facebook).

I also made some animations with HTML5 that shows the users how to install and use the bot.

I loved to use new technologies and make something without precedent on the market. I've had to study Slack, bots, and new ways to interact with this platform.

OE University | Educational Platform

Platform Workflow + Platform Design
Rebranding + Icon Font
- - - - - - - - - - - - - - - - - - - - - - - - -

This project in particular is one of my favorites. I loved working with the students and teachers; making their work easier, clearer, and more attractive.

I architected this educational platform and designed its UI/UX. The brand was redesigned with predefined colors, and the last challenge was to propose switching from a plain web design to a new, innovative, and intuitive platform interface, resulting a simpler, clearer, and more useful tool for teachers and students.

One important detail was the creation of the icons, and that the icon font that was to be totally personalized for this project. This was done via a very simple, but judicious use of color and size of each icon through a CSS stylesheet.

ARENA | Binary Trading

Branding Design + Website Design
Front-End Development + HTML + CSS
- - - - - - - - - - - - - - - - - - - - - - - - -

On this project, I've been asked to create a shocking brand and a website full of content. The main idea of this site is to make a quick comparison between the different brokers and to quickly differentiate the better one.

I made the logotype very simple but striking with strong and heavy fonts and powerful & contrasting colors; this aided in creating a vibrant and interesting result.

I had made a previous website with the information so I needed to make a redesign according to the new brand style guidelines. I made a few changes on the structure optimizing the legibility and usability.

I also developed the front-end HTML with CSS3 animations, JavaScript, and Sass.

LOOK | Social Application

App Workflow + Design
- - - - - - - - - - - - - - - - - -

The Look app is an interesting social app that helps users meet cool people.

The idea is to have a very simple, direct, and attractive way to find people near you and establish the first contact by chat.

On this opportunity I proposed, in first instance the workflow and wireframes of the app, and made an InVision presentation showing the interactive idea of each screen. After studying and testing the wireframes, I proposed a design following a predefined brand.

The main challenge was to make a first screen with large images, and giving relevant importance to the information that users want to check at first view, as age or distance. We have to catch their attention and make the search as simple and attractive as possible.

As result, we have a logic, clear, and intuitive platform, very quick and easy to use.

Social Call Center

Platform Redesign + Website Design
Front-End Development + HTML + CSS
Personalized Icon Font
- - - - - - - - - - - - - - - - - - - - - - - -

This is a call center's platform with different user profiles (administrator -+operator).

I was asked to design the administrator’s dashboard and the single-page website introducing the platform.

What I got at the beginning of the project was a previous design with a defined color group, typography, and structure. So I started creating a logotype and a very clean aesthetic that communicates all the benefits of the platform.

The result was extraordinary. At first view, the administrators can check the different call centers' performance and switch to different views (daily, weekly, or monthly) and visualize their stats in real-time.

I designed personalized icons, created an icon font to make it simplest and faster when loading, and made the HTML and animation of this site. I used HTML5, CSS3 animation, and Sass.
