Hi, I'm Aidan
Senior software engineer. I find the problems nobody scoped, and ship the fix.
Selected work
Sent to migrate an auth tenant. Found master passwords committed to the repo, and a user table where one account in ten was still in use. Neither was in the ask.
Rebuilding authentication for a multi-tenant platform →
Vistar Media (Acquired by T-Mobile)
Senior Software Engineer (2025 — Present)
- Rebuilt authentication for a multi-tenant SaaS platform, replacing home-rolled session auth with the company's central identity provider: corporate SSO, MFA, email verification, session expiry, and an audited impersonation system that retired a long-standing set of employee master passwords. Reconciled every user and company into the central store across platforms that shared no common identifier.
- Rebuilt the team's code review process. Reviewer rotation replaced all-hands assignment, assignment now fires an automatic notification, and the team authored its own review standards. Rubber-stamp approvals and multi-day waits became consistent, substantive reviews, and design review now happens ahead of implementation.
- Won company-wide "Dev-Ex" award for modernizing a legacy frontend build pipeline through a ~30K LOC migration, replacing an abandoned critical dependency, reducing build times from 60+ seconds to ~6 seconds, and significantly improving frontend development velocity.
