About Marek

🛠️ Support Dev Python & Automatisation | Profil Mathématiques Junior

Étudiant en Mathématiques et développeur passionné, j’ai fait le choix du freelancing pour confronter ma rigueur académique à des problématiques concrètes.

Mon profil est celui d'un "Problem Solver" : j'apprends vite, je documente mon travail et je m'appuie sur une logique mathématique forte pour livrer des solutions propres.

En quoi puis-je vous aider ?

Renfort & Support : Je viens en soutien de vos équipes pour les tâches chronophages (scripts, corrections de bugs, tests).

Automatisation Python : Création de petits outils sur mesure pour simplifier vos processus.

Maintenance & API : Intégration de services tiers et gestion de flux de données (SQL/REST).

Aide Cloud Azure : Support sur vos infrastructures (expérience sur infra de trading).

Pourquoi me faire confiance ?

Honnêteté technique : Je ne survends pas mes compétences. Si je ne sais pas faire, je vous le dis, ou je vous propose de chercher la solution.

Tarif Junior : Un investissement maîtrisé pour un travail rigoureux et une grande disponibilité.

Culture de l'apprentissage : Ma formation en maths me permet de monter en compétence très rapidement sur de nouvelles technos.

Disponible pour des missions courtes/moyennes. Mon objectif : vous faire gagner du temps tout en continuant de progresser.
