Backend Systems & Data to Modernize Internal Tools
I assist teams and companies whose internal processes are becoming fragile, manual, or difficult to scale.
I design and implement reliable backend systems to structure data, ensure business process reliability, and replace unstable solutions.
Objective: Transform informal processes into robust, maintainable, and documented services.
What I Implement
- Internal APIs to structure and expose data
- Robust backend services (validation, error handling, logging, monitoring)
- Integrations between existing tools (third-party APIs, internal services)
- Reliable automation of critical business processes
- Clean and reproducible deployment (Docker, Linux)
Technical Approach
- Clear data and business logic modeling
- Prioritize reliability and maintainability
- Simple architecture
- Documentation and deliverables usable by the team
Stack
Python (FastAPI) • Rust • Docker • Linux
Python for rapid integration and business APIs.
Rust for components requiring performance, robustness, or intensive processing (critical backend services, system tools, specialized engines).
Types of Engagements
- Replacement of scripts that have become critical with structured backend services
- Structuring internal data and exposing it via API
- Implementation of backend services for internal tools
- Ensuring reliability of integrations between existing systems
- Development of high-performance backend components in Rust
Collaboration
Clear scope, defined deliverables, short or iterative engagements possible.

- FreelanceFull-Stack DeveloperTRANSPORTATIONOctober 2025 - Today (8 months)Paris, FranceQuizeval — Backend & Production Infrastructure Architecture (Lead Engineer)I designed and developed the entire backend architecture as well as the production infrastructure for Quizeval, a B2B evaluation platform for automatic questionnaire generation and direct export to Google Forms.Objective: Build a clean, reliable, and easily scalable system capable of integrating external services and running in production without friction.Main Responsibilities:Domain-Driven Architecture (DDD)Designed a clear Domain / Application / Infrastructure separation to ensure testable, maintainable code structured around business logic.Fully Typed FastAPI BackendDeveloped a robust asynchronous API with strict validation (Pydantic, Mypy, Ruff).Stable contracts, solid models, predictable behavior.Automatic Google Forms GenerationImplemented the export engine to Google Forms, dynamically creating ready-to-use questionnaires for training centers.Smoke Testing SystemSet up automatic health checks to ensure infrastructure reliability and detect regressions as soon as they appear.Custom Database (SQLite + Domain Models)Designed the schema, business validations, and managed operations through strongly typed models.Containerized Infrastructure (Docker) & OrchestrationReproducible dev/prod environments, multi-service builds, isolated execution, and simplified maintenance.Reverse Proxy & Automatic HTTPS with CaddyProduction-grade configuration, TLS management, clean routing, stable performance.Deployment & Self-hosting on HetznerServer setup, security, monitoring, service continuity.This project allowed me to cover the entire backend cycle: architecture, code quality, infrastructure, external integrations, deployment, and platform reliability.https://quizeval.pro#
- Redstone FormationsDevOps and QML TrainerEDUCATION AND E-LEARNINGJune 2024 - July 2025 (1 year and 1 month)Paris, FranceI designed and led technical training sessions for developers on DevOps practices (CI/CD, GitHub Actions, Docker, cloud deployment) with guided projects. The goal: learn to structure clean workflows, automate recurring tasks, and understand the basics of maintainable software infrastructure. Each module included practical, production-oriented projects to anchor learning in concrete use cases.
- FreelanceTechnical WriterEDUCATION AND E-LEARNINGMarch 2024 - April 2024 (1 month)Paris, FranceWrote educational material for an introduction to cybersecurity, inspired by OverTheWire challenges. The content guides learners through low-level security issues (SSH, Unix permissions, etc.) with progressive hints and external resources. The objective: enable beginners to progress autonomously while offering material for more advanced profiles to explore.This assignment also allowed me to consolidate my pedagogical skills, which I occasionally use for targeted technical training.
