Razvan Cristian L.

I've run my own studio since 2014, built Android from source (CyanogenMod 12.1 for the LG Optimus 3D Max) in 2015, and shipped production Flutter since 2018, before Flutter 1.0. I lead the teams that ship it. Since 2019 my studio, Upcode, has delivered 20+ products for clients on iOS, Android, web and desktop, most of them as long-term partnerships. The agency has a 100% Job Success Score and over $1M earned across 22,000+ hours on Upwork. Where I'm most useful: - Apps that must work offline: local storage, sync queues, conflict handling, connectivity you can trust, for crews working on job sites with no signal. - Regulated and hardware-close work: encrypted messaging for financial services, configurators for industrial control boards over BLE, USB and Protobuf. - Platforms, not just screens: the mobile apps plus the backend (Firebase, gRPC), admin console and release pipeline. - Rescuing projects: one client put it as "He came into a difficult project that had made some mistakes along the way. He and [his] team have been able to clean up any issues." - Release engineering: CI/CD, store releases, hotfixes and Shorebird code push, so a fix reaches users in hours. Leading teams: Head of Development for a Swiss AI company's consumer app (2020 – 2021), building and leading a six-person team from first build to the App Store. Since 2019 I've also led and placed six Flutter developers on client work, from a mentee's first pull request to a 5,000-hour engagement. Clients describe it as "a team which was lead by Razvan our outstanding lead developer." Teaching and community: founder and organizer of GDG Baia Mare (2019 – 2022), Flutter trainer for eight Google Atelierul Digital cohorts (2020 – 2023), speaker at droidcon London 2023 ("Executing Dart code in background with Flutter"), Flutter Festival Bucharest 2022 and Flutter Warsaw 2020. Open source: SpaceTabLayout (1.5k★), flutter_i18n, rich_editor, material_pickers, firebase_dart_sdk, plus commits to Flutter, FlutterFire and freezed. With a product designer on the team, we take a product from first screens to the App Store.
