What I Do Best
Data Scraping & Extraction
Expert in building scalable web scraping systems for e-commerce, social media, and enterprise data needs. Proficient with Scrapy, Selenium, Puppeteer, Playwright, and custom scraping architectures.

My Sweet Spot
I'm most effective on projects that combine my unique mix of skills. Here's where I add the most value:
Data Collection → Dashboard
Projects that need both automated data extraction AND a frontend to visualize it. I can build the entire pipeline from scraping to display.
Complex Data Engineering
Large-scale scraping systems that need sophisticated anti-bot solutions, data validation, and reliable pipelines.
Full-Stack SaaS Applications
Complete web applications with backend APIs, database design, and modern React/Vue frontends.
Desktop Automation Tools
Cross-platform desktop applications for data processing, automation, or specialized business workflows.
To set expectations:
I'm less experienced with mobile app development (iOS/Android native), game development, blockchain/Web3, or DevOps/infrastructure-heavy projects. For these, I'd recommend specialists in those areas.
