Akra Dev is a team of developers who plan, launch, and operate products. We spend 80% of our time on our own services and 20% on partner projects.
Problems we meet in operation shape the next product and every partner engagement.
We keep finding and solving market problems. By operating businesses across SaaS, B2C platforms, and more, we learned how to build products that last.
We join projects where technology is central to the business. Together we review requirements, product structure, and post-launch operation.
For each project, we choose technology we know well. We consider operating stability and maintenance cost together.
We build for iOS and Android with Flutter, balancing delivery speed and experience.
We build fast web apps with React and Next.js, from landing pages to complex dashboards.
We design server architectures on AWS and Google Cloud that withstand changing traffic.
We work with you at every stage, from validating an idea with an MVP to improving a live service.
We align on the problem and user flow, then build small and test. We record decisions and the next work.
Before deciding what to build, we align on why it is needed.
We first map the screens and paths people will actually use.
We break features into reliable pieces with an operating-ready architecture.
We validate, ship, and record what to check during operation.
