Project: Python DSA Mentor & Problem-Solving Expert for Amazon OA Preparation I’m preparing for my upcoming Amazon Online Assessment (OA) and looking for an experienced Data Structures & Algorithms (DSA) expert who can help me practice and master Python-based problem solving. The work will focus entirely on Python and will involve solving a structured set of problems—ranging from classic interview-style questions (arrays, strings, trees, dynamic programming, graphs, etc.) to a few deeper, project-level challenges. What You’ll Do Receive a problem statement from me (sometimes alongside my initial attempt). Deliver a clean, idiomatic, and well-structured Python solution, with comments where necessary. Optionally include unit tests or sample test cases. Provide a clear explanation of the approach, the core logic, and the reasoning behind key decisions. Break down the time and space complexity, including any useful trade-offs or optimisations. Suggest possible alternative strategies if they improve understanding. Work Style This will be an iterative, interactive collaboration. After each solution, I may have follow-up questions or may request refinements. Responsiveness, clarity, and the ability to explain concepts simply are important. Requirements Please share: A brief summary of your DSA background Any competitive programming, teaching, or mentorship experience One example of a Python algorithm/solution you’re proud of (short description or code snippet) Ideal Candidate Strong in Python and algorithms Experienced in interview preparation or competitive programming Comfortable explaining ideas at both basic and advanced levels Reliable and responsive If you’re someone who enjoys breaking down complex problems and teaching through clean code, I’d love to work with you.
