Hi, I am Alex Nechyporenko
Web Scraping Engineer & Python Automation Developer
High-quality data extraction • Anti-bot bypass • API automation • Custom scraping solutions
I am a Python Developer specializing in high-performance web scraping, browser
automation,
and backend API development. I build reliable data pipelines that successfully bypass
anti-bot and Cloudflare protections, extract structured data at scale, and automate
complex
workflows.
I help businesses unlock high-quality web data without bot blocks, instability,
or high maintenance costs.
My focus is on delivering clean, structured datasets (JSON, CSV, API format) and
creating fully-automated systems with monitoring, retries, proxy rotation, and
error-resistant
workflows.

Web Scraping Case Studies - High-Load & Anti-Bot Systems
🎧Music Dataset Scraper + FastAPI
Production-oriented scraping system for collecting and serving music metadata from protected sources via a REST API.
Problem: Music data was protected by Cloudflare and unavailable
via public APIs.
Solution: Designed a resilient scraping pipeline with
Cloudflare bypass and a FastAPI backend for structured access.
Architecture: Asynchronous scraping workers with proxy
rotation, incremental storage, and a FastAPI service layer exposing
normalized data via REST.
- 30,000+ songs and albums collected from Cloudflare-protected pages
- Stable scraping with proxy rotation and retry logic
- REST API built with FastAPI for structured data access
- Incremental updates to avoid duplicate records
💻IT Vacancy Aggregator
Scalable job aggregation platform with asynchronous scraping, data normalization, and incremental update logic.
Problem: Job data was scattered across multiple platforms with
no unified format.
Solution: Built an asynchronous aggregation system with
normalization and incremental updates.
Architecture: Modular async scraping pipeline with
source-specific adapters, centralized normalization, and incremental upserts
into PostgreSQL.
- 12,000+ vacancies aggregated from 2 job platforms
- Async scraping pipelines with proxy rotation
- Incremental updates to track new and updated vacancies
- Unified data model for consistent storage and querying
🚍Car Rental Data Collector
High-performance data collection pipeline for JavaScript-rendered websites using browser automation.
Problem: Rental listings were rendered dynamically and loaded
slowly via browsers.
Solution: Optimized Playwright-based automation with async
pipelines to significantly improve performance.
Architecture: Playwright-based browser pool with controlled
concurrency, async task orchestration, and performance-optimized data extraction
flow.
- 5,000+ rental listings collected from JS-rendered pages
- 5×–8× performance improvement via async pipelines
- Optimized browser automation with controlled concurrency
- Reliable execution with retries and error handling
