Investing in Flutter experts pays off

LeanCode is an official Flutter Consultancy company. We are among the Top Global Flutter firms, and our team members take part in global Flutter conferences and meetups as speakers. Our Flutter Developers can bring to your in-house team great skills and wide industry knowledge. They can facilitate knowledge transfer and guide your team in Mobile Development efforts.

When do you need Flutter Staff Augmentation?

Need a Senior Expert to lead the projectYou have a Flutter development team, but you are missing a person who would support you in making critical decisions regarding technology choices, frameworks, and tools. In many cases, senior developers interface with clients or stakeholders, understanding their requirements, communicating technical aspects, and ensuring alignment between technical solutions and business needs.
Acceleration of the Mobile DevelopmentWhen you are already working on a mobile application but want to scale up the development efforts and manpower by bringing experienced developers to work in hybrid teams or work on some independent modules/services within the app.
Experience a temporary skill gapWhen you require specific skills for a project that your in-house Flutter team lacks, Flutter staff augmentation provides temporary access to those skills without the need for permanent hiring. You get to work with Flutter developers who are high-performing and don’t need additional guidance apart from well-specified tasks.
Need access to specialized talentFor specialized projects requiring niche skills or expertise, staff augmentation allows access to professionals with specific Flutter knowledge without the need for extensive training. Our Flutter Developers have experience developing complex app functionalities even for demanding industries such as Fintech and Banking.
Unsatisfactory state of app developmentYou either observe that the app is working too slowly, bugs are mounting, or bad reviews are starting to take over the app rating. Our Flutter developers can bring a fresh perspective on the current state of your application, including code quality and the app’s performance, and are able to support your team in solving current development challenges.
Increased project scalabilityDuring periods of increased workload or when taking on larger projects, augmenting staff helps in meeting project demands without overburdening your existing team. Our Flutter Developer or Developers can join your team for a specific time period, but at the same time, they will act as full-time members of your team, staying engaged and proactive.
