About Michael

I am Michael, I have been managing tech projects since 2014 and developing since 2017. In recent years, I have specialized in AI tools and the integration of AI into platforms and the development of AI voice agents.

I bring my clients product and technical expertise to always find the best solutions for the success of their projects. I am interested in the quality framing of projects, especially for making the right choices from the start.

If you need to develop complex full-stack features (Ruby On Rails, Node, Vue.JS, React.JS, Api, Chrome Extensions) or to lead a technical team by making the right choices, implementing quality processes, or getting a project on the right track, I have rich and successful experience to support you.

✅ Full front and back development of your websites, platforms, applications: Backend: Ruby, RubyOnRails, or NodeJs Express, TypeScript, ApiRest or GraphQL, Firebase, Supabase.
Databases: PostgreSQL, MongoDB, Redis, MySQL
Frontend: ReactJS, VueJS + Bootstrap, MaterialDesign or Tailwind Css, Chrome extension
Deployments: CI/CD, Docker, Heroku, Terraform, Aws, GCP, Dokku
Data: Microsoft Power BI, Metabase

Do not hesitate to contact me. I will answer your questions or offer advice on your project.

I am used to remote work and we can agree on the communication tools that suit you for the success of the mission. I can travel occasionally or more regularly in the region where I live.
