We are looking for a highly skilled backend developer / API expert with deep technical knowledge and strong problem-solving ability. This project involves finding and working with APIs from the Goethe website, which is not easy or publicly documented. The developer must be capable of analyzing network requests, understanding how the website communicates with its backend, and identifying the required API endpoints correctly. Important Note: This is a challenging task. The API is hard to find, and basic or beginner-level developers will not be suitable. Only apply if you have strong experience in API discovery and backend analysis.

Hello, I've worked extensively with reverse-engineering undocumented APIs by analyzing network traffic, inspecting requests/responses, and identifying authentication patterns. I understand the Goethe website integration requires deep technical analysis rather than simple API documentation reading. My approach: I'll use browser DevTools and proxy tools like Burp Suite or Charles to capture all requests between the frontend and backend. I'll identify authentication mechanisms (tokens, cookies, headers), endpoint structures, payload formats, and rate limits. Once mapped, I'll document the API behavior and build reliable integration code that handles edge cases and potential blocks. I've done similar work with systems that deliberately obscure their APIs - financial platforms, booking systems, and educational portals. I focus on clean, maintainable code and thorough testing so integrations remain stable even if the source site updates. Questions: • What specific data or functionality from the Goethe website do you need to access? • Are there any timing constraints or rate limits I should prepare for? I'm confident I can map the API architecture correctly and deliver working integration code you can rely on. Thanks and best regards, Kamran

Hello, I specialize in reverse-engineering undocumented APIs through deep backend analysis. I've successfully discovered and integrated hidden endpoints from complex systems by intercepting network traffic, analyzing request patterns, authentication flows, and response structures. For your Goethe website project, my approach will be: • Inspect all network requests using browser DevTools and proxy tools like Burp Suite or mitmproxy • Analyze authentication mechanisms (tokens, cookies, headers) • Identify API endpoints, parameters, and payload structures • Document the complete API workflow with tested examples • Build a reliable integration that handles edge cases and rate limits I've worked on similar challenges where documentation didn't exist - mapping out entire backend systems by studying XHR calls, WebSocket connections, and encrypted payloads. I understand this requires patience, technical depth, and systematic testing. Questions: • What specific data or functionality from the Goethe website do you need to access? • Are there any legal or usage restrictions I should be aware of before starting the analysis? I'm ready to tackle this challenge and deliver clean, maintainable code with full documentation of discovered endpoints. Thanks and best regards, Faizan

I am Sumit Joshi from Sacesta Technologies. I can handle API discovery on complex sites by tracing network traffic, mapping request flows, and turning the findings into a stable, well-documented backend integration. • I will do this only in a compliant way: using your authorized access, respecting rate limits, and avoiding any bypass of authentication, bot protections, or restricted endpoints. If Goethe provides an official API or partner access path, I will prioritize that first. • Discovery workflow: capture and classify requests, identify core endpoints, headers, tokens, pagination, error patterns, and data contracts, then validate with repeatable test calls. • Output: a clean API map, Postman collection, and a small service layer (Node or Python) that wraps the endpoints with retries, caching, and structured logging for reliability. • Hardening: change detection, graceful fallbacks, and a monitoring checklist so the integration does not break silently if the site changes. • Relevant experience: I have built robust API integrations and automation-heavy systems where undocumented or poorly documented backends required careful traffic analysis and strict reliability practices, similar to CRM and workflow platforms like HustlerGuys CRM. To start: I need the exact Goethe pages and actions you want automated, plus a test account you control for validation. Regards,

Hello, This project clearly requires an advanced level of backend expertise, and it aligns well with my experience in API discovery, reverse engineering, and deep network-level analysis. I have worked on multiple projects where required APIs were undocumented or intentionally abstracted behind complex frontend interactions, and I am comfortable dissecting such systems methodically and responsibly. My approach involves analyzing browser network traffic, request headers, payload structures, authentication flows, and session handling to accurately identify backend endpoints and understand how the web application communicates with its services. I focus on building a clear internal API map, validating request-response behavior, and documenting each endpoint for reliable integration or further development. I bring strong problem-solving skills, attention to detail, and the ability to work through technically challenging environments where trial-and-error and surface-level inspection are not sufficient. The goal is not only to locate the correct APIs but to ensure they are used correctly, securely, and sustainably. If needed, I can also assist with abstraction layers, reusable service modules, or secure backend integrations once the endpoints are identified. I understand the sensitivity and complexity of this task and will approach it with the level of rigor it demands. Best regards, Amaan Khan P. CUBEMOONS PVT LTD.
