Advanced Browser Automation & Website Reverse Engineering Developer

**Long-Term Opportunity | Bangla Communication Mandatory** I'm looking for a highly skilled, experienced, and independent **Browser Automation & Website Reverse Engineering Specialist** for a long-term project. I need someone who can deeply analyze how websites work, understand browser behavior, investigate complex technical issues, identify root causes, and develop reliable solutions. **My priority is simple: I need working solutions, not just code.** ## Required Technical Expertise - Advanced JavaScript and/or Python programming - Tampermonkey Userscripts and Chrome Extensions - Browser Automation (Playwright, Puppeteer, Selenium, etc.) - Advanced DOM manipulation and MutationObserver - Dynamic websites, SPAs, and asynchronous JavaScript - AJAX, Fetch API, REST APIs, JSON, and WebSockets - HTTP/HTTPS requests, headers, cookies, sessions, and authentication flows - Browser DevTools and advanced network debugging - JavaScript debugging, execution flow analysis, and reverse engineering - Browser events, page lifecycle, and navigation behavior - API request/response analysis - Error detection, root-cause analysis, and troubleshooting - Performance optimization and reliable automation architecture ## Core Responsibilities **1. Complete Website Behavior Analysis** Analyze the website's functionality, frontend architecture, JavaScript behavior, DOM structure, navigation flow, browser events, and dynamic interactions. **2. Advanced Network & API Investigation** Investigate network requests, API endpoints, request/response structures, session behavior, and communication between the frontend and backend. **3. Browser Behavior & Execution Analysis** Understand how the browser processes website actions, executes JavaScript, handles asynchronous operations, manages application state, and responds to user interactions. **4. Independent Problem Investigation** Identify the actual cause of technical problems without depending entirely on step-by-step instructions. **5. End-to-End Problem Solving** Design, implement, test, and optimize complete technical solutions rather than providing partial fixes or temporary workarounds. **6. Long-Term Maintenance** Maintain and update automation solutions as websites change, resolve compatibility issues, and continuously improve stability and performance. ## Complete Technical Freedom You are free to select the most suitable technologies, programming languages, frameworks, and technical approaches. You are not limited to Tampermonkey. You may use JavaScript, Python, Playwright, Puppeteer, Selenium, browser extensions, backend services, APIs, or other appropriate tools. **I care about the final result, reliability, and effectiveness — not which specific tool or method you use.** All technical approaches must be secure, authorized, and appropriate for the project. ## What I Expect I need a developer who: - Thinks independently and approaches problems analytically - Understands how modern websites and browsers actually work - Can investigate complex issues using browser and network debugging tools - Can identify root causes instead of repeatedly applying temporary fixes - Can develop complete, reliable, and maintainable solutions - Can adapt when websites change their structure or behavior - Takes responsibility for testing and verifying their solutions - Communicates clearly and provides meaningful technical explanations **I do not want someone who simply follows instructions or writes basic scripts. I need a technically capable problem-solver.** ## Long-Term Collaboration This is an ongoing project, not a one-time assignment. The websites involved may change regularly. Therefore, I need someone available for continued development, debugging, updates, optimization, and maintenance. ## Mandatory Language Requirement **You MUST understand and communicate effectively in Bangla (বাংলা).** All project requirements, technical discussions, troubleshooting, and ongoing communication may be conducted in Bangla. Please do not apply if you cannot communicate in Bangla. ## How to Apply Please include: 1. A brief introduction and your technical background 2. Examples of relevant browser automation, website analysis, or reverse engineering projects 3. Your experience with JavaScript, Python, Tampermonkey, and browser debugging 4. Your approach to investigating complex website behavior and technical problems 5. Your availability for long-term collaboration 6. Your estimated timeline and hourly or project-based rate Shortlisted candidates may be offered a small paid technical assessment based on a real project requirement. ## Final Note **I'm hiring a problem-solver, not just a programmer.** If you can independently investigate complex website behavior, understand browser and network operations, identify technical problems, and deliver reliable end-to-end solutions, I'd like to hear from you. **Only experienced developers with relevant expertise and Bangla communication skills should apply.**
