Martin in a few words

Je peux me déplacer dans vos locaux si vous le souhaitez. Je suis basé à Paris.

La première étape est de bien cerner votre problème, puis de travailler main dans la main afin de développer la solution ou le produit qui vous conviendra.

Je possède de l'expérience en développement embarqué (STM8, STM32 et nRF52 avec BLE) ainsi qu'en développement C et C++ sur Linux/MacOS/Windows.
J'ai conçu des moteurs de jeux 2D embarqués pour des usages spécifiques avec C++.

Je suis également expérimenté avec React Native pour concevoir des application iOS et Android ainsi que concevoir des infrastructures serveurs avec GraphQL.

Je recommande à 200% Martin qui a développé mon app avec rapidité, rigueur et force de proposition ce qui est très rare. Il ne se contente ainsi pas juste de répondre à votre besoin mais il va jusqu'à suggérer des idées permettant d'améliorer l'expérience utilisateur et les implémente. Au delà de ses compétences techniques indéniables, Martin a les compétences relationnelles qui permettent de travailler très facilement avec lui et d'avoir des échanges fluides et constructifs. Et le fait qu'il soit full stack est un réel atout si vous souhaitez confier à Martin un projet global nécessitant du front et du back. Enfin Martin met un point d'honneur à respecter ses engagements ainsi que le planning sur lequel il s'est engagé. Vous pouvez faire appel à ses services en toute confiance.

Dynamique, motivé et autonome c’est toujours un plaisir de travailler avec Martin. Ses compétences sont solides et je le recommande sans aucun soucis.

I feel lucky to have met Martin and worked with him, especially at Poleon where he was lead developer. And where he originated, as he often does, a big boost in the technological development. In only a week, Martin mastered all the existing tools. And he successfully: -Renewed the entire infrastructure -Containerized every service -Configured and maintained databases -Deployed websites, APIs -Created monitoring tools I am always very impressed by his fast learning and by his ability to write code efficiently, and very clearly. In addition, Martin is a very good communicator, it is a pleasure to work with him and I recommend him without any reservations.

I was lucky enough to work on Poleon with Martin. Martin is one of the cleverest developers I've worked with. Even though he’s young, he has a strong general knowledge on pretty much anything around tech. He’s able to give you a clear overview of which technology you should use for each specific situation. But the most impressive thing about him is his ability to learn. For even the most complex tech, he’s able to quickly pick up and use something he never worked with before. At Poleon, he laid down the basis of a complex infrastructure (Node.js, Docker, Cassandra, Mongo) in just a few days. You can trust him completely when you need someone to catch up and fix your problems really fast. He’s still relatively cheap so enjoy him now before he becomes too expensive!

    - Networking (tcp)

    This is a new-generation school, with no teachers, no planning. It would be a pleasure for me to explain you how it works and what I learned in details.
