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