I help product teams make their Flutter apps easier to evolve and their releases more reliable.
Architecture, testing and technical leadership: embedded in your team, or through a focused audit.
Lyon, France · remote · 🇫🇷 version française

18 years in software development. Rated 5.0 out of 5 from 12 client reviews on Malt. Worked with Renault Digital, SNCF Connect & Tech, Thales and Zanalys.



01 / Expertise: the code matters, and so does everything around it. Build to last: clarify responsibilities, manage state and prioritise technical debt (Flutter, Dart, BLoC, Riverpod, Clean Architecture). Make delivery dependable: automate delivery, test critical journeys and improve production monitoring (CI/CD, Fastlane, GitHub Actions, Firebase, AWS, Crashlytics). Help the team move forward: weigh architecture choices, review code and share knowledge (tech lead, code review, mentoring, product thinking). Put AI agents to work, safely: frame coding agents with lints, tests and a clear definition of done, and review what they produce before it ships.



02 / Experience you can build on. Renault Digital, Senior Software Engineer, March 2025 to present. SNCF Connect & Tech, Senior Developer Dart / Flutter, August 2022 to March 2025. Zanalys, Senior Flutter developer in healthcare, since January 2023. Easivio, co-founder, 2019 to 2022. Thales, software engineering and team management, October 2014 to November 2019.



03 / Products: I also build for myself.

Tripveri, travel tech, in progress: tailored trips built around what you want. Next.js, TypeScript, Supabase, AI. Rewvy, SaaS for retail, in progress: a digital loyalty platform for merchants. Flutter, React, NestJS.

Simulfin, fintech web app in beta: bring stocks, crypto and property together in one consolidated view. Tikipik, photo app in beta testing: create and order photo products from your phone. Flutter, Firebase, e-commerce.

Spoolkeep, maker tool: manage 3D printing filament spools and costs, with data kept on the device. Flutter, Bloc, SQLite. Volutea: 3D-printed home objects and an online store. Astro, React, Stripe.

Pixhella, completed project co-founded within Easivio: a photo-sharing network with a print service. Watch the demo. Easivio, co-founded 2019 to 2022: mobile widgets displayed on Android TV. Watch the demo.


04 / A fresh technical perspective: DEVLOPN Audit. DEVLOPN Audit: know where your app stands before a release, a rewrite or a funding round. Three tiers from €990 excl. VAT, 5 to 10 working days, 8 review areas, Flutter and native iOS and Android, report reviewed and signed.



05 / In their words: a good project is a team effort. “His strong technical expertise helped us make several crucial architecture decisions, combining rigour, pragmatism and a real ability to bring others along.” Quentin Payré. “As a senior Flutter/Dart developer, Jérémy brought a long-term vision to our projects, anticipating future needs and proposing suitable, scalable technical solutions.” Patrick Raguin. “Highly involved in the team, he stands out for his common sense and ability to challenge both technical and functional choices, always in service of the product and the user.” Marie Postic.



06 / Writing: notes from the audit desk, in French.

07 / Toolbox: what I ship with, plus a few shadow clones. None of them ships unreviewed. Flutter, Dart, Kotlin, Swift, Firebase, AWS, GitHub Actions, TypeScript, React, Next.js, NestJS, Supabase, Astro, Figma

BLoC · Riverpod · Clean Architecture · Fastlane · Bitrise · Crashlytics · AWS Lambda · DynamoDB · Cognito · unit, widget & golden tests · Claude Code & AI agents



08 / Activity: commit by commit. Most of my work lives in private client repositories. A snake eating the contribution graph of the last twelve months
