Hi there, I understand you need a professional backend developer to build a **Product Filtration & Status Update Engine** using Python, managing a large PostgreSQL database, integrating multiple external APIs (including slow-response and CAPTCHA-protected APIs), and handling asynchronous background tasks to ensure system stability and performance. I have extensive experience developing Python systems with FastAPI and Flask, optimizing PostgreSQL databases for millions of records using indexing, implementing asynchronous processing with Asyncio and Celery, and integrating Webhooks and REST APIs while maintaining reliable, scalable data flows. I will design the core engine to process incoming data, implement API calls using a Waterfall logic (handling VPN and CAPTCHA where required), manage background tasks to prevent bottlenecks, update product statuses automatically, and send/receive Webhooks to ensure system synchronization—all delivered as clean, documented, and scalable code with technical support during the testing and initial rollout phase. Q1: What is the expected daily update volume and number of records processed per day? Q2: Is there a fixed list of external APIs to integrate, or should the engine be designed to easily add new APIs in the future? Q3: Should the system generate notifications or reports for each product after filtering and status updates? Best regards, Stratos

Hi, I will build the filtration engine — core Python service on Windows 11, PostgreSQL optimized for 1M–10M records with proper indexing and partitioning, and waterfall API logic with async processing via FastAPI and asyncio. For the slow VPN-bound APIs with captcha, I will implement connection pooling with retry/backoff strategies and integrate a captcha-solving layer, while running checks concurrently so one slow API does not block the entire pipeline. Webhook listeners will trigger background jobs instantly upon new data arrival. Questions: 1) How many external APIs are involved in the waterfall chain, and do any require specific VPN protocols? 2) What is the expected daily volume of incoming webhook events? Looking forward to discussing further. Best regards, Kamran

@devendrathakur12

Hello, I would love if I get the chance to work on your project. I built large scale backend system and building scalable backend systems with Python, FastAPI, PostgreSQL, AsyncIO, Celery, and REST APIs is work I genuinely enjoy because reliability becomes critical as data grows into millions of records. I focus on clean architecture that remains easy to maintain and extend over time. One question I have is, when different APIs return conflicting statuses during the Waterfall process, should the engine follow a fixed priority order or apply a configurable confidence based resolution strategy? Can we connect over a chat to discuss more about the project? Best regards, Dev Singh

@Friends4it

Hi, I reviewed your requirements for the filtration engine and product status update system. We have strong experience building high-performance Python backends with FastAPI/Flask, PostgreSQL optimization, and API integrations. We can deliver: - Core filtration engine as a local Windows 11 service with clean, modular Python code - PostgreSQL database designed for 1-10 million records with proper indexing for fast queries - External API integrations with waterfall logic, VPN rotation, and CAPTCHA handling - Asynchronous background jobs using Celery/RQ for queue processing without blocking the UI - Webhooks & REST APIs for company system integration and real-time product status updates - Robust error handling, logging, and monitoring Our approach: build the core engine first with clean architecture, then layer in API integrations with proper retry logic and rate limiting. We have experience with large-scale data processing pipelines and PostgreSQL performance optimization. At Global IT Vision, we bring 15+ years of backend development expertise. We can start immediately. Would you like to discuss the API integration priorities and data model? Best regards, Muhammad Idrees CEO, Global IT Vision Pvt. Ltd

@DeveloperStation

Hi there, I’ve been developing web apps for over 15 years and working with Python for more than 8 years. I’ve built several large-scale products using Python frameworks like Django and Flask, and I’m well-versed in both asynchronous and synchronous programming. I recently developed a product that involved integrating multiple external APIs to fetch and process data, which aligns closely with your requirement for a filtration engine. As a full-stack developer, I can also handle front-end tasks using modern frameworks like React and Vue, ensuring you don’t need to hire a separate developer for those tasks. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m looking forward to hearing more about your exciting project. Best, Adil

@OlektraGroup

Hi, You need a robust backend engine to process 10M+ records in PostgreSQL while orchestrating complex, asynchronous API waterfall calls—including VPN-routed requests and CAPTCHA handling—without blocking your core service. I’ve built similar high-throughput pipelines for computer vision projects where I processed massive image datasets using `Asyncio` and `Celery` to prevent I/O bottlenecks. For your system, I propose using `FastAPI` with an `AIOHTTP` connection pool to manage concurrent API requests efficiently. To ensure sub-second queries on 10 million rows, I will implement partial indexing and BRIN indexes in PostgreSQL to minimize disk I/O. I successfully optimized a license plate detection pipeline that handled high-frequency data streams reliably. What is the average response latency you are currently seeing from the slowest external API?

@C0RETECHIES

مرحباً، أتفهم أنك تحتاج إلى محرك فلترة يعمل في الخلفية. يستقبل النظام بيانات جديدة عبر webhook، ويضعها في طابور مهام، ثم يقوم عامل (worker) بالتحقق من حالتها عبر سلسلة من واجهات API الخارجية (بعضها بطيء ويتطلب VPN و CAPTCHA). أخيرًا، يتم تحديث الحالة في قاعدة بيانات PostgreSQL ضخمة. النهج التقني: سنستخدم FastAPI للأداء غير المتزامن، مع Celery و Redis لإدارة المهام الخلفية بكفاءة. بالنسبة لقاعدة بيانات PostgreSQL، سنقوم بتصميمها مع فهارس (indexes) محسّنة للاستعلام السريع على ملايين السجلات. سيتم التعامل مع CAPTCHA عبر دمج خدمات خارجية. الوحدات الأساسية ستشمل نقطة استقبال الـ Webhook، وعامل الفلترة الذي ينفذ منطق الشلال (waterfall logic)، وطبقة وصول بيانات محسّنة. لقد قمنا ببناء أنظمة أتمتة معقدة تعالج البيانات عبر خطوات متعددة بشكل غير متزامن، وهو ما يطابق سير العمل الذي تحتاجه. نبدأ بالنواة الأساسية ثم نضيف الواجهات المعقدة تدريجياً، مع اختبار الأداء تحت الضغط لضمان الاستقرار.

I understand you need a Senior Python Backend Developer to build a "Filtration engine" that receives data, checks it via external APIs, and updates a large PostgreSQL database. I’ve previously built and deployed similar high-volume data processing systems in Python, achieving a 99.9% uptime and reducing processing time by 40%. I will develop the core Python engine as a Windows 11 local service using FastAPI for efficient API handling and SQLAlchemy for robust PostgreSQL interaction. The database schema will be optimized for rapid inserts, updates, and queries, handling millions of records. I'll implement asynchronous tasks for API polling and integrate error handling for external service calls. What is the expected rate of data ingestion and the typical response time required for external API checks? Ready to start as soon as you confirm scope.

أفهم أنك تحتاج محرك فلترة يدير ملايين السجلات، يستدعي واجهات خارجية بترتيب شلالي ويتعامل مع VPN و captcha بدون تعطيل النظام على Windows 11. هذا هو التحدي الحقيقي هنا. المشكلة ليست فقط في الاستدعاءات البطيئة بل في ضمان تحديثات متسقة للقاعدة مع إدارة ضغط الطلبات وإعادة المحاولة الذكية وتجنب ازدواجية التحديثات. عملت على مشروع Watch Trader OS حيث بنيت منظومة جمع بيانات من مصادر بطيئة مع Celery وPostgreSQL للتعامل مع ملايين السجلات وتحديث الحالة بشكل موثوق. خطتي العملية 1) واجهة FastAPI محلية تعمل كخدمة على Windows 11 مع endpoints للادخال و webhooks 2) طابور مهام بـ Celery و Redis لمعالجة الخلفية، مع سياسات retry و circuit breaker 3) منطق شلالي لكل رقم مع دعم VPN عبر proxy session وإمكانية استخدام خدمات حل captcha أو نقطة تحقق بشرية 4) تصميم قاعدة PostgreSQL بفهارس ومخازن مؤقتة batch updates وعمليات upsert آمنة 5) توثيق وتسليم كود مع دعم للاختبار والديبولوي الأولي هل يمكنك إرسال مواصفات APIs التجريبية وعدد الاستدعاءات المتوقعة في الدقيقة وعينة صغيرة من البيانات؟ سأجهز مخطط معماري أولي بناء على ذلك.
