Description

Are you looking for a Node and React Tech Lead?

You've come to the right place.

I am a software engineer with over 10 years of experience.

I have worked in Tech Lead positions for the last 5 years.

I have collaborated with companies such as OCTO Technology, Randstad France, Django (Groupe La Banque Postale), ...

My goal is to continuously deliver value to users. To do this, I have been specializing for over 5 years in Craft, Agile practices, and DevOps culture. This ensures that users have a bug-free application or one that is fixed very quickly.

My development approach avoids the creation of "technical debt". This debt is often the reason why companies redevelop an entire application every 2 years... This will prevent your company from losing money, without increasing development time.

I am able to assist you with:

- Developing your frontend in React.js, Vue or Angular

- Developing your backend in Node.js, Typescript, Java, PHP, ...

- Refactoring complex Legacy code

- Migrating complex Legacy code

- Implementing architectures adapted to the needs (Clean Architecture, Microservices, CQRS, Event Sourcing ....)

- Implementing practices such as code reviews, Clean Code, pair/MOB programming, ...

- Coaching and training teams in Craft practices (TDD, DDD, ...)

- Agile coaching (Lean, Scrum, Kanban, ...)

- Agile, Lean Startup, Accelerate and DevOps acculturation

- Facilitating EventStorming

Shall we discuss your projects?
