Description

I help companies design, evolve, and scale .NET and Azure systems in production, with a specialization in the seamless integration of AI features (Azure OpenAI, LLMs) into existing products.

Senior backend engineer with over 7.5 years of experience. For the last 3.5 years, I was the technical lead for a critical subsystem at TestDome: migrating legacy Windows workloads to Docker and AKS, designing an AI response validation service on Azure OpenAI, and revamping CI/CD and QA processes, which reduced release time by approximately 70%. Before that, 3 years at Société Générale on a high-traffic distributed pricing and calculation platform on Azure, processing around 1 million requests per day.

What I typically deliver:

- Production-grade backend services in C#, .NET, and ASP.NET, with properly implemented CI/CD, testing, and observability.

- Azure architecture and implementation, from AKS-based platforms to managed services.

- AI integration into existing .NET applications: LLM-based features, multi-model infrastructure, prompt engineering, and cost optimization.

- Containerization and Kubernetes migrations from legacy Windows stacks to production-ready AKS environments.

- Frontend contributions when the mission requires (TypeScript, Vue.js, React).

How I work:

- End-to-end ownership of a system or feature: Analysis, design, implementation, production deployment, and long-term reliability.

- Short technical interventions (PoC, migration plan, architecture audit) or longer engagements.

- Fluent in French and English, comfortable with distributed teams.

If you're looking for a senior .NET and Azure engineer who can also reliably integrate AI into your product, I'd be happy to discuss your project.

August 2022 - March 2026 (3 years and 7 months)
Technical lead for the live coding evaluators subsystem at TestDome, the critical component that compiles, runs, and evaluates candidate code across over 12 languages for the online recruitment platform.

- Led the migration of live coding evaluators from a legacy Windows infrastructure to Docker and Azure Kubernetes Service (AKS), improving reliability, fault isolation, horizontal scalability, and production deployment safety.

- Designed and deployed a new AI-powered response validation service on Azure OpenAI (C# and .NET), with a fine-grained abstraction over the OpenAI SDK allowing the content team to autonomously create AI-graded questions. The service now powers 32 production questions covering essay, system design, and prompt engineering formats.

- Revamped the browser-based live coding evaluator: improved performance by an average of 5x and enhanced sandbox isolation for untrusted user code. Also built a new PostgreSQL live coding service, which now evaluates over 7,000 candidate submissions per month.

- Formalized the evaluators' QA process (unit, integration, and regression testing) and revamped CI/CD pipelines on Azure DevOps, reducing release time by approximately 70% and significantly decreasing production regressions.

- Replaced outdated OAuth flows in the SSO layer (Microsoft Entra ID): migrated the public ROPC API to Authorization Code and Client Credentials, and guided clients and integration partners through the transition with minimal impact.

- Regular code reviews on backend and frontend, author of design proposals, cross-functional collaboration with the content team, and L2/L3 incident management in rotation with other developers.

September 2021 - August 2022 (11 months)
Québec, Canada
Senior backend engineer on a Health and Safety at Work (HSW) SaaS platform built on a .NET microservices architecture and deployed on Kubernetes with a per-tenant instance.

- Contributed to the audit and inspection management microservice (C#, ASP.NET, PostgreSQL, Entity Framework): delivered new features for audit and inspection forms, and fixed a backend bug that prevented clients from submitting their forms via the mobile app.

- Participated in the integration of a recently acquired risk analysis product, Dilygence (PHP with Symfony, and ElasticSearch), into the HSW platform. Optimized tenant migration scripts to ensure reliability even for large clients, and fixed a series of ElasticSearch synchronization bugs.

- Introduced integration tests to the risk analysis codebase, raised the standard of code reviews, and mentored an intern. Quickly gained proficiency in a partially new stack for me (PostgreSQL, PHP and Symfony, Docker).

July 2018 - August 2021 (3 years and 1 month)
White House, Morocco
R&D engineer on a high-traffic distributed pricing and calculation platform used by several entities within the Société Générale group, processing approximately 1 million requests per day. Fully deployed on Azure, built with C#, .NET, and .NET Core.

- Developed and evolved pricing calculations using internal quantitative libraries, including regulatory calculations required by the European PRIIPs KID framework.

- Redesigned inter-service communication and centralized CPU-intensive processing into dedicated worker services, reducing request processing time by approximately 15%.

- Implemented dynamic client/worker pool assignment, configurable at runtime without service redeployment. This provided the ops team with a quick lever to isolate noisy tenants and protect priority client SLAs in a multi-tenant context.

- Restructured transient data on Azure Blob Storage, moving from one container per request to one container per day. Storage and purge costs decreased, and lifecycle management was simplified.

- Proposed and participated in replacing Azure Batch with an internal batch API built on top of the existing calculation platform, preserving the client-side contract while reducing operational overhead.

- Managed production incidents and improved observability across the entire stack using Azure Application Insights and KQL. Mentored 2 interns (both subsequently hired full-time), onboarded 3 new hires, and participated in technical interviews.

Tech: C#, .NET, .NET Core, ASP.NET, Azure Service Fabric (native services and Actor API), Azure API Management, Azure Queue Storage, Azure Blob Storage, Azure Application Insights, NUnit, Serilog, KQL, TeamCity.
