Agency development support from Banja Luka in CET/CEST
I support agency web and app projects from Bosnia and Herzegovina, working in CET/CEST with English communication. The engagement can cover a defined build or an agreed part of an existing codebase.
Agency overflow work needs clear ownership: who talks to the client, who approves scope changes, which repository receives the work and who maintains the result. A lower headline rate does not resolve an unclear handover.
I work with React, Next.js, Flutter, FlutterFlow, Webflow, Firebase and Supabase as the project requires. My portfolio includes a UK clinic platform, Callidus OS, and maintained FlutterFlow marketplace work. UK collaboration normally has a one-hour time difference; meeting windows and response expectations are agreed for each engagement.
Before estimating, decide whether the work is white-label, whether I join client calls and who signs off deliverables. Provide the existing brief, design files and repository context. A named acceptance owner helps avoid conflicting feedback from the agency and end client.
For an existing project, agree code review, branch conventions and deployment responsibility. For a new build, agree access to source code, hosting and third-party accounts. Delivery should include the instructions the next developer needs to run and maintain the project.
The Callidus OS case study describes a UK clinic product and its handover. The FlutterFlow portfolio covers template and custom widget work. These show different kinds of delivery; choose the reference that matches your project instead of assuming one stack fits every client.
