How Fil & Muz can help.
Architecture and system evolution
Understand existing systems, examine technical dependencies and plan the next stages of development. Architecture advice stays connected to hands-on coding.
Frontends and performance
Reusable components, clear user journeys and faster loading. The focus is on modular frontend architectures using TypeScript, Vue and Web Components.
Automation and AI integration
Automate recurring build and release tasks. AI can extend applications with document analysis, summarisation or classification, using defined tasks and results that can be checked.

Approach
From requirements to working software.
Understand
Start with the business need, existing code and interfaces. These determine the scope and sequence of the work.
Decide
Technical decisions account for the existing stack, maintainability and effort. The reasoning forms part of the discussion with the project team.
Build and verify
Modular components, automated tests and CI/CD support development, making changes verifiable and releases repeatable.
Collaborate
Work is carried out remotely from Germany. Technical questions, dependencies and pending decisions are discussed directly with the people involved.
Experience
Experience in practice.
Fil & Muz draws on Sinan Uçar’s experience with business-critical backend systems, distributed enterprise applications and modular web interfaces.
