High-Load Protected Data Acquisition & API Delivery System

Project Overview

Designed and implemented a resilient high-volume data acquisition system with a FastAPI- based backend layer for structured data delivery. The system operated under advanced anti- bot constraints while exposing clean, programmatic access to normalized datasets.

Business Context

Critical data sources were protected by browser-level defenses and rate limiting. At the same time, internal stakeholders required reliable, structured API access to continuously updated data.

Solution

Built a hybrid acquisition architecture combining adaptive request strategies, browser automation (when required), structured normalization, and a FastAPI service layer for controlled data exposure.

Architecture Highlights

  • Hybrid HTTP + browser automation strategy
  • Proxy rotation and adaptive retry logic
  • Async ingestion pipeline
  • Central normalization layer
  • FastAPI backend exposing REST endpoints
  • Structured storage in PostgreSQL
  • Dockerized deployment

Tech Stack

Python FastAPI asyncio multiprocessing Playwright PostgreSQL Docker

Results

  • 30,000+ structured records collected
  • Stable operation under protection constraints
  • API-based data access for downstream analytics
  • Controlled failure rates with monitoring & recovery
