The useful week is spent comparing the interface to the API, fixing mismatches, and recording the source of truth, with mistakes corrected in the open rather than buried. Responsibilities - Review the field map for the renamed fields and correct it before anyone else relies on it. - Keep a single current error-state catalogue, and archive the older copy once you have dealt with the unhandled status codes. - Ask the reviewer who checks both layers to challenge the source-of-truth note, especially around the two places that disagree. - Write the assumption behind the sample payload in two or three plain sentences, and mention the missing required fields. - Compare this week's cache note with the previous one and explain the stale values. - Stop and rework the regression check if you find a path that used to work. Requirements - Roughly 3 to 7 years of keeping a user interface and its API in agreement that matches this full-stack developer profile, or a shorter record with the same kind of finished work. - Practical skill with browser tools and an API client in full-stack developer work, not a certificate alone. - Able to explain which layer is wrong when the screen and the database disagree to a colleague who was not in the room. - Careful with caches that hide a failed save; this is checked in review of full-stack developer work. - For the full-stack developer brief in Toronto, use the working language of that assignment in Canada.
