What I'm looking for

I seek roles building data-rich web applications and reliable scraping pipelines, with collaborative teams, strong engineering practices, and opportunities to scale systems and impact public-data insights.

I am a Ruby on Rails developer focused on building data-driven web applications, RESTful APIs, and scalable scraping infrastructure for public-sector data.

I have designed and maintained applications that manage and visualize procurement and contract data, built full-text searchable interfaces with Elasticsearch, and created interactive dashboards using React.js and mapping libraries to provide actionable insights.

My web-scraping work includes designing, deploying, and maintaining 80+ bots using Ruby (Watir, Mechanize), handling anti-bot protections, and automating data pipelines to ensure continuous availability of public data.

I bring operational experience deploying and scaling Rails apps on Heroku and AWS, implementing CI/CD and DevOps practices, and managing geospatial databases and GIS solutions to support field operations.
