Hi, I can help debug and fix your Python script so it runs reliably and efficiently. I’ll first profile the current code to identify what is actually blocking execution, then trace the API calls, session handling, Flask routes, and other bottlenecks. I’ll fix the underlying bugs rather than just patching symptoms, improve error handling and request performance, and test the updated script to make sure it works correctly. I can get started right away and provide a clean, working version with the key issues explained.

Your Python script has performance problems and you need someone to profile it and find what is blocking it. I have 8+ years of experience in web development and have delivered hundreds of projects using Python. I will run your script with a profiler first, so I can see exactly which parts eat the time. Then I fix the real cause, not just the symptom, and test again until it runs clean. I am fully confident I can deliver this for you, and I will give my 100% until it works exactly the way you want. Unlimited revisions until you are satisfied. I can start right away.

Hi there, I can help you with your Python script that is currently not performing as expected. I'll start by profiling the code to identify bottlenecks, assessing its performance metrics, and determining the underlying issues that are causing it to fail. After identifying the problematic areas, I can implement optimizations to enhance its efficiency, ensuring it runs smoothly. Understanding the specifics of your script and its intended functionality would be helpful for targeting optimizations effectively. Looking forward to discussing how we can improve your script's performance! Ali

Hi, I'm Denis, a full-stack developer specializing in debugging and optimizing performance-critical Python systems. I've repeatedly found that the assumed bottleneck isn't the real one—profiling always reveals the truth. Your script is likely crashing, hanging, or running unusably slow due to memory leaks, inefficient loops, blocking I/O, or incorrect NumPy usage. I'll start by running cProfile to identify exactly where time is being spent, then analyze the data flow for obvious inefficiencies like repeated calculations or unnecessary copies. My approach is straightforward: profile the code, pinpoint the bottleneck, then optimize accordingly—whether that's vectorizing NumPy operations, fixing algorithmic issues, or restructuring logic. The main variable is scope. Sometimes a single line fixes everything; sometimes the architecture needs rethinking. Profiling will tell us exactly what we're dealing with. I can start immediately. Let's discuss the details. Thanks, Denis.

Your script is likely hitting memory bottlenecks or inefficient loops that cause it to hang or crash under load. Without proper profiling, you're debugging blind. Quick questions - are you processing large datasets that could exceed available RAM? And is this running on a single-threaded process that needs parallelization? Here is the architectural approach: - PERFORMANCE TUNING: Profile with cProfile and memory_profiler to identify bottlenecks, then refactor hot paths using NumPy vectorization instead of Python loops. - DEBUGGING: Trace execution flow with logging and breakpoints to isolate where the script stalls or throws errors under real-world conditions. - LINUX: Optimize resource allocation using system monitoring tools to ensure the script runs efficiently within your server's CPU and memory constraints. I've debugged similar performance failures in data pipelines processing 10M+ records that were timing out. Let's schedule a 15-minute call to review your profiling data and scope the fix.

Hi, A script that "doesn't work" rather than just runs slow usually means it's stuck in one hot spot — a pure-Python loop over rows that should be a NumPy vectorised operation, or growing a list/array inside a loop until memory blows up. First I'd run it under cProfile plus a memory check to see which function eats the time, then rewrite only that part and keep the rest of your code and output as-is. Does it hang forever, crash with an error, or finish but take far too long — and roughly how large is the input?

Hi there Sounds like your script is stuck or crawling way too slow. First step is profiling it properly with cProfile or line_profiler so we see exactly where time goes, not just guessing from reading the code. Most of the time it is one of these: huge data loaded into memory when chunks would work, slow loops over NumPy arrays that should be vectorized, blocking I/O in the hot path, or a logic bug making it spin forever. I will trace the flow, fix the bottleneck, and confirm it runs clean on your Linux box. Recent Python work: data pipeline tuning https://www.freelancer.com/projects/api-developmet/Python-Data-Engineering-for-Brisbane, platform optimization https://www.freelancer.com/projects/python/Football-Betting-Platform-Milestones, and script debugging https://www.freelancer.com/projects/computer-vision/Document-Defect-Detection-System. Send the script, a sample input, and what good output should look like. I can get this sorted within a day.

Hi there, I can debug and profile your existing Python script to identify exactly what is causing the performance issues and why it currently fails to run efficiently. I’ll inspect the code flow, profile CPU/memory usage, identify slow loops, blocking I/O, inefficient database/API calls, or concurrency issues, and trace any runtime errors contributing to the problem. After identifying the bottleneck, I’ll optimize the relevant sections without unnecessarily rewriting working logic, then benchmark the before/after performance to verify the improvements. I’ll also explain the root cause and document the changes so the script is easier to maintain. I can start immediately and work directly with your existing codebase. Best Regards, Avinash
