Building a microfrontend architecture for an internal banking platform.

At Bereke Bank I led frontend architecture for internal banking system projects, building the platform’s frontend infrastructure from zero.

Some implementation details are omitted due to confidentiality.

As Frontend Tech Lead for internal infrastructure, I designed and adjusted the microfrontend architecture from the ground up, set the frontend team’s development workflow, mentored developers, and led code reviews.

The platform was built as a monorepo with a shared design system, using Webpack 5 and Module Federation to compose independently built applications under a single shell, with Lerna managing the monorepo and Storybook documenting shared components.

React 18 was the framework across applications, giving every internal team a consistent runtime and component contract to build against.

I adjusted the frontend team’s development workflow around the new architecture, introducing consistent code review practices and mentoring developers as the platform and team grew together.
