About Montassar

Comment je peux vous aider :
J'accompagne les entreprises et les e-commerçants dans la création de plateformes web et mobiles performantes. Mon rôle est de transformer vos besoins métiers en solutions techniques scalables, en garantissant une expérience utilisateur fluide et une infrastructure robuste. Que ce soit pour le lancement d'un MVP ou l'optimisation d'une architecture existante, j'interviens sur l'ensemble du cycle de vie de votre projet.

Ma valeur ajoutée :
Ce qui me différencie est ma double expertise de Lead Developer et d'ingénieur DevOps. Contrairement à un développeur classique, je n'écris pas seulement du code : je conçois des systèmes distribués capables de supporter une forte charge tout en automatisant les déploiements pour réduire vos délais de mise en production. Ma maîtrise de l'UI/UX sur Figma me permet également d'assurer une cohérence totale entre le design et le produit final.

Types de projets et livrables :
  • E-commerce : Développement et maintenance de boutiques sous PrestaShop et sites WordPress sur mesure (thèmes et plugins spécifiques).
  • Applications Web & Mobile : Développement Full-Stack (React, Next.js, Node.js) et applications mobiles cross-platform avec Flutter.
  • DevOps & Cloud : Audit de performance, conteneurisation via Docker/Kubernetes et mise en place de pipelines CI/CD.
  • Livrables habituels : Code audité, documentation technique complète, prototypes haute fidélité et rapports d'optimisation de performance.

Langues et disponibilité :
Certifié IELTS 7.5 (Anglais niveau C1), je travaille quotidiennement avec des clients internationaux. Je suis disponible pour des missions en remote ou hybrides, avec une approche basée sur la méthodologie Agile pour une transparence totale sur l'avancement de vos projets.
