I build

I build the systems nobody sees and everybody relies on — APIs, automation bots, and data-extraction pipelines that turn messy real-world documents into clean, structured data.

About

Backend by trade, automation by obsession.

I'm a backend developer who specializes in the unglamorous, high-stakes middle of the stack: reliable APIs, resilient scraping and bot infrastructure, and document-extraction pipelines that parse thousands of PDFs into data teams can actually use.

My day-to-day toolkit spans Python and Node.js / TypeScript, with automation built on Scrapy, Playwright, and Puppeteer, deployed and operated on Google Cloud Platform. I care about error handling, observability, and code the next engineer can read without a map.

Projects

Selected work.

Multi-carrier PDF Extraction Engine

Extraction pipeline that parses insurance EOB and claims PDFs from dozens of carriers into structured, validated JSON — with per-carrier extractors and defensive error handling for corrupted or malformed files.

  • Node.js
  • TypeScript
  • PDF parsing

Distributed Scraping Infrastructure

Bot fleet built on Scrapy, Playwright, and Puppeteer for reliable large-scale data collection — session management, retries, and observability baked in.

  • Python
  • Scrapy
  • Playwright
  • Puppeteer

Cloud Automation Pipeline

GCP-based infrastructure for scheduling, running, and monitoring automation workloads — containerized services, CI/CD, and cost-aware scaling.

  • GCP
  • Docker
  • CI/CD
