I live in Seattle with my wife and cats - currently passionate about building AI tools, biking, and building prototypes with 3D printing. After 7 years in shipping logistics, I automated myself into redundancy, then was caught in a 50% downsize. I'm now looking for new problems to solve and learn from involving:
- Machine learning / ANNs / AI
- Data analytics and pipelines
- System architecture and schema design
- Building search engines and data visualization tools using document vectors, LLMs and knowledge graphs
Backend Senior Software Engineer
EasyPost
April 2017 - Jan 2025
Developing scalable and reliable API services with Python, MySQL, Rust, Ruby, Kafka, and many other tools.
April 2017 - Jan 2025
- Led the design and implementation of an in-house address verification system that replaced a slow, unreliable, and expensive external API call. The final service was implemented in Rust, runs 50x faster and has had no service level outages, and resulted in large annual savings.
- Designed and implemented multiple extractions from an overloaded monolith and DB. They were completed on time with no break in service or changes in API behavior. This included rigorous testing and careful migrations.
- Participated in design and implementation of the back end for new API products: carbon offsets, insurance purchases, and analytics tools for customers. The last also powers a web based analytics tool, and continues to perform well for real-time queries as we grow.
- Teach architecture, schema design, and language concepts to junior developers.
- Improvements to developer experience, build scripts, and CI/CD system. Used industry standard tools and practices: TDD, CI/CD, VMs, AWS, Github
