À propos de Olivier

Independent lead / mobile/full-stack engineer (10+ years) for European and international teams. I help product companies ship and stabilise serious software 100% remotely—from architecture and backlog trade-offs through hands-on implementation, tests, integrations, CI/CD, and production releases.

What I typically do

Turn messy ideas into concrete scope: roadmap support, spikes, refactor plans, pragmatic delivery slicing.
Build and evolve consumer & B2B mobile apps (native & cross‑platform), plus lighter backends/APIs, payments & billing, analytics, notifications, auth, and observability-minded foundations.
Step in flexibly—as solo engineer, short architecture/audit sprint, acting hands-on tech lead, or helping you recover before a flagship release
.
How I prefer to collaborate

Fluent English (default for international engagements). Native French speaker, when you prefer French conversations. Comfortable across EU time zones, with workable overlap toward Asia‑Pacific.

Breadth

I’m stack-agnostic, pragmatic; recent depth includes Flutter/Dart, Swift/SwiftUI, React Native, and typical Firestore/Supabase-style backends, but onboarding into your codebase is routine.

Track record highlights

Shipping Scout (teamscout.app) — team operations mobile + backends; accelerator-backed product path. Earlier: medically sensitive training software (clinical partnerships & international deployment), flagship consumer launches (featured store recognition when applicable), localization-heavy engineering, and technically driven delivery leadership alongside enterprise campuses.

Contracts, invoicing, and invoicing geography are clarified per jurisdiction at kickoff—I’m straightforward about remote-only timelines, availability, and what “done” means for your mission.

  • Master's degree
    European Institute of Technology

    EPITECH is an engineering-style computer science school centred on project-based learning rather than chalk-and-talk theory. Across several years students design, build and ship progressively larger software artefacts—solo and in squads—with reviews, refactoring, tooling, infra basics, and pragmatic delivery. The ethos is explicitly “learn by doing”: you’re graded on runnable systems and cross-functional collaboration, closer to professional product labs than textbook exams. Tracks typically stress fundamentals usable in production — algorithms and systems thinking embedded in implementations, UNIX-style environments, C/C‑style grounding in many curricula, networked services, concurrency, scripting, persistence, scripting for automation, modest DevOps familiarity, defensive coding, and iterating under pressure. Presentation and peer feedback mirror how studios and startups actually work—short cycles, ambiguity, demos, rework. Degrees are positioned toward engineering practice (“Expert in Information Technology”) for roles that prototype, integrate, automate, operate, debug, mentor—without implying a narrowly academic researcher profile. For context in my trajectory: EPITECH also supported an exchange year abroad (for me Keimyung University, Korea)—useful grounding in adaptation, multilingual collaboration, compressed cultural context, exactly the freelancer skill set on cross-border engagement
