I'm looking for an experienced engineer to help with network traffic analysis of a third-party iOS application, focused on understanding request patterns and API structure. Scope includes: Analyzing HTTPS traffic generated by an iOS app Identifying and categorizing major request types (authentication, messaging, sync, status, profile, etc.) Producing clean, human-readable API documentation (endpoint purpose, request/response fields) Explaining the full methodology used for analysis (tools, workflow, thought process) Deliverables: Step-by-step guide to set up the capture environment (so I can reproduce the analysis myself) API summary document covering the main endpoints identified above Important notes: This task is strictly for technical research and learning. No automation, botting, or production usage is required. App name and details will be shared only after initial qualification discussion. Required experience: Strong knowledge of HTTP/HTTPS Experience analyzing iOS app traffic Familiar with tools such as Charles, mitmproxy, Wireshark Ability to explain why, not just what Hidden screening requirement (please answer in your proposal): What tools do you usually use for iOS traffic analysis? How do you normally deal with HTTPS certificate pinning? When analyzing unknown APIs, how do you determine the meaning of request parameters? Candidates who provide clear methodology explanations will be prioritized.
