Python Development - Internship

Selected intern's day-to-day responsibilites include:

1\. Develop Python scripts to automate API request emulation using .har (HTTP

Archive) files for testing and automation purposes, including parsing HAR

files to extract endpoints, headers, cookies, and payload data.

2\. Implement robust HTTP clients using libraries such as requests, httpx,

curl_cffi, and TLS client to replicate browser-level API interactions with

proper header management, session handling, and cookie persistence.

3\. Build multi threaded/asynchronous automation systems for efficient

concurrent API request processing, implementing proper thread pooling, rate

limiting, and retry mechanisms to handle large-scale API operations.

4\. Reverse engineer and replicate complex authentication flows, including

OAuth 2.0, JWT tokens, session-based authentication, CSRF tokens, and custom

security headers, to ensure seamless API integration.

5\. Design and implement request rotation systems with proxy integration,

user-agent spoofing, and TLS fingerprint management.

6\. Create comprehensive error handling and logging systems to track API

failures, response validation, timeout management, and automatic retry logic

for failed requests.

7\. Develop API wrapper libraries and reusable modules that abstract complex

request patterns, making automation scripts maintainable and scalable for

future use cases.

8\. Perform debugging and network traffic analysis using tools like Wireshark,

mitmproxy, and browser DevTools to identify API endpoints, parameters, and

required headers for successful request emulation.

9\. Optimize request performance through connection pooling, keep-alive

sessions, response caching, and efficient data serialization/deserialization

techniques.

10\. Document automation workflows, API specifications, code architecture, and

create technical guides for maintaining and extending the automation systems.
