Vision: Improve my clients businesses by creating the best web applications, with a smile :-)
More than 30 projects done alone or with a team, in 11 years working as Ruby on Rails Freelancer. Business focused. Prioritizing the best communication with clients. Let’s write the specs and I will build it for you.
Ask yourself the following questions:
Have you lost a lot of money in non-profitable developments?
We should go to production in less than 3 months with our very best Minimum Valuable Product.
Are you experiencing expensive software maintenance due to Architectural needless complexity with APIs, React, Angular, Vue,... ?
I create React-equivalent modern frontends, cheap and easy to maintain, thanks to Hotwire JS-library, completely adapted to Ruby on Rails Backend. Without code duplication: APIs, models, validations, functions etc... No need to contract Fontend Developers yet.
Bored of breaking something on every code change?
I grant over 90% of your code covered by automated tests, running before every deployment, to ensure that nothing else breaks nowhere.
Tired of waiting weeks to see a new feature working in your site?
I grant you will see everyday changes thanks to daily automated deployments. No need to contract QA Engineers yet.
Is your site slowing down due to users growth?
I build High Scalability systems taking care of Rails performance, and based on containers and microservices, adapted automatically to your business growth. No need to contract Devops Engineers yet.
Did you experience poor communication with your Development Team?
I will send you a daily email with things to-do and done, based on business planification. And all talks you need, of course.
