About Morgan

Python Backend Developer | FastAPI | AI Agents | REST API | SaaS

Does your project need a solid, scalable backend capable of interfacing with the outside world?

As a Python backend developer specializing in FastAPI, I focus on the design and development of REST APIs, SaaS architectures, and automated data pipelines. I implement AI agents to synchronize, enrich, and orchestrate data from external sources (public APIs, ERPs, CRMs, third-party services).

What I concretely work on:

REST API development with FastAPI and layered architecture
AI agent design for data synchronization and orchestration
SaaS backend development and technical MVP construction
External API integration (Stripe, ERP, CRM, ADEME, INSEE, Web Services)
Business process automation and scheduled tasks
Microservices architecture and asynchronous management
Secure authentication (OAuth2, API key, JWT)
PostgreSQL optimization, Alembic migrations, Docker containerization

I have worked on various projects: RGE matching platforms, multi-system ERP integrations, social multi-API architectures, SaaS MVPs with online payment.

Main Stack: Python, FastAPI, PostgreSQL, SQLAlchemy async, Docker, Redis, OAuth2, APScheduler.

Available to discuss your project. Response within 24 hours.

Education

  • Master's degree in Application Development Engineering
    AEN
    2025
    Pendant mon master, j'ai développé des compétences variées, notamment en anglais, JavaScript et PL/SQL. J'ai également appris à gérer des projets en entreprise, en m'occupant de la note de cadrage, des parties prenantes, des livrables, des tâches, des charges, des responsabilités, de la communication, du planning et de la gestion des risques. En programmation, j'ai travaillé avec Python pour la vision par ordinateur, ainsi qu'en cybersécurité avec un focus sur les attaques, la recherche et la veille d'information. J'ai également utilisé Flutter pour le développement mobile, et approfondi la sécurité web, la cryptologie, la rétroconception et l'OPSEC. Sur le plan technique, j'ai maîtrisé XML, notamment l'écriture de DTD, de schémas XML, l'optimisation de définitions dans les schémas, l'écriture de feuilles de transformation, et l'interrogation de documents XML avec XPath. J'ai aussi étudié la programmation orientée système, ainsi que les systèmes et réseaux, avec une expertise en réseau Linux, Bash, et Docker.
  • Advanced Programming Bachelor's Degree
    University of Pau and Pays de l'Adour
    2023
    Durant ma licence en programmation avancée, j'ai approfondi mes connaissances dans plusieurs langages de programmation, notamment C++, Symfony, JavaScript, Node.js, et Vue.js. Cette formation m'a permis de consolider mes compétences en développement, tant sur le front-end que sur le back-end. J'ai également eu l'opportunité de découvrir et d'approfondir mes connaissances sur différentes bases de données, telles que Cassandra, Redis, et Neo4j. Ces expériences m'ont permis de mieux comprendre les spécificités des bases de données relationnelles et non relationnelles, ainsi que leurs applications dans divers contextes. Par ailleurs, j'ai travaillé en mode projet en appliquant des méthodes récentes comme Agile et Scrum, ce qui m'a permis d'acquérir une expérience concrète en gestion de projet et en collaboration d'équipe.
