Auth and access
Cognito, claims, roles, sign-in redirects, account linking, token validation, and client portals.
Software rescue
I help teams inspect stuck systems, identify the highest-leverage fixes, and make focused changes in .NET, Blazor, Python, AWS, auth, integrations, and business apps.
Cognito, claims, roles, sign-in redirects, account linking, token validation, and client portals.
AWS configuration, environment drift, email deliverability, storage, API wiring, and failing releases.
Blazor/.NET bugs, Python services, data workflows, admin dashboards, and integration failures.
I read the failing path, reproduce or reason through the symptom, and identify what evidence is missing before changing code.
If the fix is bounded, I implement it. If the problem is bigger, I hand back the shortest credible path to stabilize the system.
Logs, screenshots, stack traces, and current deployment details are useful but not required for first contact.
