hi, i'm jake

Senior Software Engineer

I build the backend behind large partner integrations: event-driven services, REST APIs, and the AWS infrastructure holding them up. Currently doing that at Ibotta.

who's this

about me

I'm a backend software engineer in Denver with 8+ years building and running distributed systems on AWS. At Ibotta I own the architecture of the event-driven services and REST APIs behind our partner network, which includes publishers like Walmart, 7-Eleven, DoorDash, and Instacart.

A lot of my time goes into the parts that keep things running: queue processing that keeps going when a partner's API doesn't, observability set up before there's an incident rather than after, infrastructure you can rebuild from source. Enough years of on-call will do that to you.

Originally from Portland, Oregon, I moved to Denver in 2018 and haven't looked back. The mountains are a big part of my life — skiing in winter, backpacking and rafting in summer. I'm also into live music, barbecue, and in my free time I enjoy exploring real estate and personal finance, including managing my own Airbnb property.

  • Owned architecture and development of event-driven backend services and RESTful APIs supporting a partner network spanning Walmart, 7-Eleven, DoorDash, and Instacart.
  • Designed extensible, Terraform-managed AWS infrastructure enabling rapid onboarding of high-traffic enterprise partners with zero-downtime deployments.
  • Architected a CDN-backed image delivery pipeline (API Gateway, S3, CloudFront) serving tens of millions of low-latency product images per day.
  • Drove observability improvements through Datadog dashboards, Runscope API test suites, and BlazeMeter load testing — reducing mean time to detection on production incidents.
  • Led 24/7 on-call rotations, owning incident response, root cause analysis, and stakeholder communication for a high-traffic production platform.
  • Won an internal hackathon building an image resizing and compression service that reduced annual data transfer costs by $100,000+.

  • Built the platform's backend services and data layer from scratch on AWS — DynamoDB, SQS/SNS messaging, S3, and API Gateway — to support high-throughput event processing and real-time partner integrations.
  • Authored Terraform modules to provision and version-control all infrastructure, enabling repeatable, auditable, and environment-parity deployments.
  • Led cross-functional delivery across 3+ engineering teams, owning risk management, dependency mapping, and milestone tracking from design through production release.
