Projects
Over my career, I've built large-scale patent data systems for clients worldwide.
Tech Stack: Go, Javascript, Typescript, Python, Docker, Elasticsearch/OpenSearch, AWS, Oracle, MySQL, CI/CD, Lucene, Logstash and more
Here's a sample of what I've delivered:
AI-Powered Patent Tools
- Patent Connector - Hosted MCP Server that connects ChatGPT, Claude, and other AI tools directly to patent databases (EPO OPS, USPTO ODP, DPMA Connect Plus). Available for self-hosted implementation.
- AI-Driven Claim Dependency Tree Builder - Automatically analyzes and visualizes dependency relationships between patent claims
- AI-Driven Claim Features Analyzer - Extracts and analyzes technical features and elements from patent claim language
Side Projects
- PTO Sync - Automatically synchronizes USPTO office actions, payment notices, grants, and deadlines with patent management systems
Open Source Contributions
- EPO OPS - Go client library for European Patent Office API
- EPO BDDS - Go client library for EPO Bulk Data Distribution Service
- USPTO ODP - Go client library for USPTO Open Data Portal
- DPMA Connect Plus - Go client library for German Patent and Trademark Office API
- Bulk File Loader - Automated patent data downloads with web UI, supporting EPO, USPTO, and DPMA bulk data
