We Build Applications that Look Great on Every Device.

Consumers are using an ever increasing variety of platforms to access services. Designing only for one type of device will leave some of your users with a frustrating experience. We design all of our websites and applications using the responsive web design approach. Otreva has been using responsive web design since the term was coined by Ethan Marcotte back in 2010, so you can trust that our designs follow RWD best practices for usability as well as performance.

Our 7 Easy Steps Website Design Process

Step 1: Brainstorm & Requirements Gathering
In this stage, we will discuss and research on various design ideas, concepts, layouts and any possible inceptions that are ideal for your business.

Step 2: Mockup And/Or Prototypes
Depending on the level of customisation, we will provide a blueprint that has an overview of the potential structure that helps with system planning.  
Step 3: Implementation & Integration
Once payment and quotation details are agreed, we will proceed to build the website. If this is a website revamp, we may require authorisation to your exisiting domain/hosting accounts.

Step 4: Website Enhancement
We will discuss on the first draft and provide design revisions and improvements based on your observations.

Step 5: Testing & Troubleshoot
Your website will undergo usability testing & code reviews so that bug fixes can be implemented as soon as possible. Frontend testing will be done in all major browsers to test for errors in scrolling, navigation and user inputs.

Step 6: Go Live

Your website will set as production mode and go live in public.

Step 7: Website Maintainence (Optional)
If you take up our package, we will help you maintain the website updates such as photo uploads or changes in keywords.
