Guild
Associate Software Engineer, Coverage SquadAug 2026 - Present
Software Engineering Intern, Benefits Administration (converted to full-time)Jun 2026 - Aug 2026
- Designed and shipped a production backend-for-frontend service from an empty repository: Python 3.13 on AWS (Lambda, API Gateway, CDK/SAM), a three-repo Auth0 M2M auth chain, canary CI/CD, Datadog observability, and Tier 0 compliance. 532 tests at 98.6% coverage; ~3K production requests served with zero 5XX errors across 3 consumers. Built the XOB Determination UI in Coverage Lookup on top of it
- Shipped 6 MCP tools to Guild's production AI gateway by extracting a protocol-neutral service layer, so support staff investigate member eligibility in natural language instead of hand-querying S3, Snowflake, and DynamoDB. Logged 1,146 calls from 31 users (100% success) in the first two weeks across 30 employer accounts, then led a follow-up epic fixing 11 request-handling defects and hardening the surface to 24 tools
- Built Wells, a Slack AI investigation agent (TypeScript, Bolt, ECS Fargate), taking it from an empty repository to use on a live production escalation in 2 days. Piloted by a second business function within a week and listed in Guild's company-wide agent index; extended with a chained deep-investigation mode and a 55-case evaluation harness (319 tests)
- Root-caused a live member escalation to a systemic split-recipient identity defect. The resulting platform sweep reconciled 762K recipient records, surfaced 1,031 orphaned authorizations, and unblocked 5 affected members before any of them escalated; closed as a repeatable playbook
- Removed a critical remote-code-execution vulnerability from a production container image, caught a PII log egress in pre-merge review of my own branch, and root-caused a silent serialization defect behind 92K production errors that three observability layers had missed
- Eliminated an IAM role leak that had made the squad Guild's largest staging IAM consumer: fixed the CDK root cause, reclaimed 373 orphaned roles with a dry-run-first nightly GitHub Action, and published the fix org-wide (a second squad adopted it the same day)
- Merged 70 PRs (+69K lines, 11 repos), closed 77 Jira tickets and 5 self-owned epics, triaged 4 production incidents, delivered a second production service (catalog-builder-api) on loan to another org, mentored a fellow intern, and wrote 5 Confluence guides including the squad's AI tooling operating guide
