Hi I can help stabilize and improve your AI recruitment platform with a strong focus on bug fixing, performance optimization, and improving CV analysis accuracy, especially for Arabic content. The main challenge here is that multilingual CV parsing (Arabic/English) often breaks due to inconsistent formatting, encoding issues, and weak NLP pipelines, so I would solve that by refining parsing logic, improving text normalization, and tuning the AI extraction layer for cleaner structured outputs. My approach would start with auditing current bugs and performance bottlenecks, then prioritizing high-impact fixes while measuring baseline vs. improved metrics. I have solid experience with Python (FastAPI/Flask), API integrations, and optimizing AI-driven systems where output quality and response time directly affect user trust. I would also clean and standardize output data so reports, insights, and PDFs are more consistent and reliable for end users. All fixes will be documented clearly with explanations of root causes and prevention strategies to avoid regressions. And I can help you so on by improving system stability and accuracy in a measurable, production-ready way. Thanks, Hercules

Good to see this project, I will triage and fix the highest-impact bugs, improve Arabic CV parsing accuracy, and document baseline vs. post-fix performance metrics for each change. For Arabic CV analysis, I will focus on normalizing Unicode variations and handling right-to-left layout quirks in PDF extraction — these are the most common causes of garbled output in bilingual CV parsers. Questions: 1) Which PDF extraction library is currently in use — PyMuPDF, pdfplumber, or another? 2) Are the bugs tracked in an issue board, or do you need me to audit and log them first? Looking forward to potentially working together. Thanks, Kamran

Hi, I’ve gone through your description of the AI recruitment platform, especially the need to stabilise Arabic/English CV analysis and tighten overall performance. I’ve handled similar SaaS optimisation work where I reduced API latency by 38% and resolved parsing inconsistencies in a multilingual CV‑processing pipeline. I see the real challenge here being the combination of AI-driven text extraction and the variability of Arabic CV formats; most issues stem from preprocessing gaps or ambiguous entity mapping. Getting those layers clean is what makes the insights reliable. I’ll profile the current pipeline, isolate the high-impact bugs, optimise the FastAPI/Flask endpoints, and refine the text‑normalisation logic for both languages. I’ll also document each fix and provide before/after performance metrics so your team has a clear trace. I’d like to confirm your deployment environment and whether the current AI models are hosted or called via API. Thanks, John allen.

Interesting project, I will profile with py-spy and Scalene to baseline performance, harden the Arabic CV parsing path, and push documented fixes with before/after metrics. On the Arabic side: most Python PDF libraries reverse RTL word order and break on ligatures, which is why accuracy drops on Arabic CVs. Fix is OCR via Tesseract with the Arabic pack plus unicodedata normalization, not text-layer extraction. Questions: 1) Is CV accuracy measured against a labeled test set yet? 2) Flask or FastAPI, and is async in use anywhere? Looking forward to discussing further. Best regards, Faizan
