Summary
Senior software engineer who leads features end to end on a retail media advertising platform, from design spike to production. I work across Java and Python services, Angular front ends, cloud infrastructure, release pipelines, and incident response, and I build AI-assisted tooling that makes on-call faster and better documented.
Experience
84.51° (Kroger Precision Marketing) | Chicago, IL
January 2023 – PresentSenior Software Engineer | May 2024 – Present
- Led the design spike and end-to-end build of a new video creative type with a branded end card across a Spring Boot service, a WebFlux API gateway, and the Angular web app, including on-demand MP4 export, three canvas sizes, and an auto-approval flow.
- Took ownership of backend production releases: built Prepare, Deploy, and Rollback workflows for two more services, retired a legacy blue/green path, and fixed four bugs in the existing pipeline, putting four services on one release model.
- Overhauled the team's incident response: audited alerting across five services, moved every monitor into Terraform, built an on-call hub of 12 runbooks tied to those monitors, and refined escalation.
- Built a Claude Code skill on the Datadog MCP server that lets any engineer investigate a firing alert and update its runbook from live log evidence; prototyped a Jira MCP server and an AI reviewer agent that scores monitor quality for noise, coverage, and actionability.
- Designed and shipped a view-only access role enforced across two services and both API versions, with contract tests for each role.
- Root-caused and fixed production issues including a message-bus startup race that blocked deploy health checks, a database migration that crash-looped staging, and video jobs killed by the wrong timeout; added per-step timing metrics to the asset pipeline.
- Shipped a new versioned keyword recommendations endpoint in a Python FastAPI service with zero changes for existing clients, and migrated four infrastructure repositories to Spacelift and OpenTofu with no destructive changes.
- Embedded with the reporting team to speed up an analytics dashboard by loading only the open tab’s data with caching, and added browser tracing for every report step.
- Reviewed 138 pull requests across 20+ repositories in 2026, against 106 of my own merged.
Software Engineer | January 2023 – May 2024
- Built and maintained FastAPI services powering core platform APIs, plus background workers on Azure Service Bus and RabbitMQ queues and topics.
- Designed a MongoDB change data capture service on change streams and Azure Service Bus, using distributed locking and idempotent processing to prevent duplicate work.
- Helped migrate services from PCF and on-prem infrastructure to Azure Kubernetes Service, and standardized shared Terraform modules, Azure PostgreSQL, and Key Vault integration.
- Built Angular features with NgRx and RxJS in an Nx monorepo, including config-driven UI that renders forms and workflows from structured configuration.
