Winning proposal14 days275 USD
1017 2 1 Winning proposal14 days275 USDHello! My main profile is high-load web scraping and automating complex processes in Python.
Why I am suitable for this task:
WorldResults Experience: I implemented a system that collects, structures, and processes vast amounts of data from various web sources. Working with tens of thousands of requests per day is a familiar task for me.
Bypassing Protection and Stability: I have experience working with protected systems, understand how to bypass rate limits, set up proxy rotation, and handle temporary failures through retry queues.
Performance: To achieve goals in the tens of thousands on a single VPS, I will choose asynchronous programming (HTTPX, Asyncio) or multithreading, which minimizes resource consumption and maximizes throughput.
…
Reliability: I will write a turnkey solution that will operate 24/7. The logic will include saving raw HTML (as you requested) and clearly sending structured data to your API.
Cybersecurity: As a student in the relevant field, I pay special attention to the security of interactions with your API (authorization, tokens) and the stability of software operation on the server.
My action plan:
I will set up quick interaction with your input API.
I will develop an asynchronous worker for parallel processing of identifiers.
I will implement the logic for saving HTML and parsing the required parts.
I will add an error monitoring system so that the script does not "crash" during network failures.
I am ready to deploy a test script on your VPS and demonstrate real performance after the first tests.

421 20 days2129 USDHello Krysztof
I have real experience, especially when it comes to building reliable scalablel automation systems with python. I have successfully built systems capable of processing hundreds of thousands of items daily under rate-limited and secured environments.
Based on the requirements, dutifully explained above, I can build a modular, containerized automation system designed for resilience and scale.
Before we begin, kindly inbox me with the following:
-Access to your input/output API documentation (or endpoints).
-Credentials/access to the target web system (or a test environment).
… -SSH access to your VPS for deployment (or a similar staging environment).
-Clarification on the exact data points to extract from each view.
Looking forward to hearing from you.
