What We Do

Built for Critical Systems

We specialize in environments where downtime and errors directly impact users and revenue.

🚨

Incident Response

Real-time handling of critical production incidents and alerts. We take ownership from start to finish using PagerDuty, Squadcast, and SolarWinds.

🔗

API & Payment Troubleshooting

Deep debugging of transaction failures, integration errors, and payment flow issues across Zelle, MX, Plaid, Payrailz, iPay, and more.

🔐

SSO & Authentication

Implementation and troubleshooting of SSO flows, login failures, token issues, and user verification across complex financial platforms.

📊

Log Analysis & Debugging

Root cause investigation through GCP log analysis, tracing, and production debugging. We find the issue, not just the symptom.

☁️

Cloud & Infrastructure

Support across Google Cloud Platform, Kubernetes (GKE), and production environments where precision and uptime are non-negotiable.
