Hello Client, I am a member of [login to view URL] and I can work with a lower budget. I have already worked on several betting-analytics and SaaS stabilization projects with similar stacks and production constraints. The main issues are an unstable Python HTTP server, unreliable email/payment flows, and mixed i18n/frontend state. I propose to: 1) Stabilize backend with systemd process management, healthchecks, auto-restart and persistent structured logging; 2) Fix email by validating SMTP credentials or switching provider, add password-recovery tests; 3) Validate Mercado Pago and Stripe in production, secure and test webhooks and add confirmation pages; 4) Repair i18n folder logic, persist language preference, fix mobile UX and add loading states; 5) Add basic security (rate limiting, CSRF tokens, headers) and SEO/performance quick wins (meta tags, sitemap, minify assets). Deliverables: production fixes, docs, test checklist, and 7-day support. Looking forward to working with you. Best regards, Gustavo.

Hi, I reviewed your project about "Optimize Betting Analytics SaaS" and noticed that you're working with a custom Python 3.10 HTTP server alongside SQLite and third-party APIs for odds and AI analysis. That tells me the main challenge here is stabilizing and scaling your backend services while ensuring reliable payment integrations and addressing multilingual frontend inconsistencies. I’ve worked on similar full-stack SaaS projects where I: - designed scalable backend APIs, - implemented secure authentication and data models, - and delivered production-ready web/mobile features. For your project, I’d suggest starting with implementing robust backend healthchecks and auto-restart mechanisms with proper log persistence. This will prevent downtime and improve fault tolerance. Parallelly, addressing the payment gateway validation and frontend i18n fixes will reduce user friction and errors. Before moving forward, I have one quick question: Could you clarify the current logging strategy for your Python backend and whether you have any monitoring tools in place? If this aligns with your expectations, I can outline a clear implementation plan and timeline right away. Best regards, Nilo

Hi, I’ve read your OddsAI Pro brief and can stabilize and finish the product end-to-end. I’ll prioritize email recovery, backend resilience, reliable payment flows and language consistency so users can buy credits and receive analyses without interruption. I bring strong Python web-server and Linux/NGINX experience plus practical work with LLMs/Transformers, chatbots, classification and vector search used in AI features. My approach: implement systemd/supervisord healthchecks and auto-restart, persistent structured logging, fix or replace SMTP, add robust input validation, validate Mercado Pago and Stripe webhooks in production, and correct i18n loading and language persistence. I’ll also fix key frontend UX issues (mobile menu, CTAs, loading states). I can deliver high-priority fixes in ~7–10 days and complete the full scope in ~14 days, with 7-day post-delivery support. I’m available ~20 hours/week. Do you have staging credentials, recent server backups and test accounts for Mercado Pago and Stripe so I can validate webhooks and payments safely in production? Sincerely, Andrew

Hello, I've reviewed OddsAI Pro's stack and the list of issues and I can stabilize and polish the product. I specialize in Python backend reliability and API design and often use Django/DRF for clean API contracts and maintainable auth systems; for your case I can harden the existing custom server (systemd/supervisor, healthchecks, structured persistent logs) or plan an incremental migration to Django if you prefer. I will restore password recovery (SMTP or alternate provider), validate Mercado Pago and Stripe webhooks in production, fix i18n folder mismatches and language persistence, and apply targeted frontend UX and performance fixes with basic tests and documentation. Deliverables: production fixes, docs, tests and 7-day post-delivery support. Do you have repository and server access (SSH and config for Nginx) plus recent server/log extracts for the crashes and failing webhooks so I can reproduce issues locally and prioritize fixes? Sincerely, Cindy Viorina
