Leoncio Jr Coronado

I build automation systems that replace manual work and continuously deliver clean, business-ready data.

I’m Leoncio Coronado Jr., a Data Automation Engineer specializing in reliable web data pipelines for e-commerce, lead generation, and monitoring workflows.

I currently maintain 10 production automation tools used by 100+ users on Apify, with a 96%+ success rate across long-running pipelines.

I don’t build one-time scraping scripts. I build systems that keep working — even when websites change.

My systems are designed to solve real operational problems:

• Automate product sourcing → generate ready-to-upload product catalogs • Build lead discovery systems → deliver pre-qualified leads for outreach • Develop monitoring pipelines → detect changes, downtime, and trigger alerts • Clean and structure messy datasets → CRM-ready, automation-friendly outputs

I focus on reliability-first engineering:

• Handles anti-bot environments (captchas, dynamic pages) • Retry logic, fallback strategies, and failure recovery • Structured outputs for integration into business workflows • Built for long-term stability, not one-time extraction

Technologies:

Python • Playwright • Scrapy • Selenium • APIs • Apify SDK

I’m open to working with businesses that need reliable automation systems, not just scripts.
