Distributed Platform
Backend services coordinated diagnostics and remediation workflows across a large fleet.
Professional Experience
Designed a distributed troubleshooting platform operating across hundreds of thousands of nodes, reducing diagnostic workflows from hours to minutes while limiting direct infrastructure access.
Backend services coordinated diagnostics and remediation workflows across a large fleet.
Designed to operate across hundreds of thousands of production nodes.
Role-based, auditable workflows reduced the need for direct infrastructure access.
Telemetry, logs, and metrics made troubleshooting behavior easier to inspect.
The Engineering Problem
Troubleshooting complex issues across a large distributed infrastructure was slow, manual, and operationally risky. The platform provided a scalable way to collect diagnostics, run approved workflows, and surface actionable information without requiring engineers to directly access infrastructure.
Supporting a large distributed infrastructure required engineers to gather data, run troubleshooting workflows, and surface actionable information without directly accessing production infrastructure.
The goal was to reduce time to resolution, improve security, and enable repeatable self-service diagnostics for a large support engineering organization.
Complex issues could take hours and required manual data collection across multiple systems.
A single issue often required correlating data from many services, clusters, and nodes.
Direct infrastructure access increased security exposure and was difficult to scale safely.
The platform needed reliable behavior across diverse environments with auditable workflows.
Goal
Reduce time to resolution, improve security, and enable scalable, self-service troubleshooting for a large support engineering organization.
Architecture Overview
Support engineers used a client-facing workflow to initiate diagnostics. A control plane handled authentication, authorization, request validation, and job orchestration. An execution layer scheduled work against distributed node agents, while PostgreSQL, Redis, OpenTelemetry, and access-control systems supported persistence, coordination, visibility, and secure operation.
Support Engineers and clients request diagnostics through a control plane. The control plane authenticates and authorizes requests, orchestrates jobs, and dispatches work through an execution layer to distributed node agents over secure communication. Supporting capabilities include PostgreSQL, Redis, OpenTelemetry, and security controls.
Request diagnostics and review results
Authentication, authorization, validation, orchestration
Task scheduling, agent selection, command dispatch
Agents collect diagnostics and execute approved commands
Jobs, metadata, and results in PostgreSQL.
Command queues, transient state, and agent heartbeats in Redis.
Metrics, logs, and traces through OpenTelemetry.
RBAC, audit logs, secure communication, and least privilege.
Scaling The Platform
The platform handled high-frequency agent communication, large diagnostic data volumes, and bursty workloads while keeping backend pressure manageable.
Local aggregation, batched check-ins, and pipelined communication reduced fan-out and lowered backend connection pressure.

Business Value
Enabled faster resolution, reduced operational risk, and improved engineering productivity.
Delivered a scalable, secure, and observable platform that became part of repeatable operational workflows.
My Role
I helped architect and build the core backend platform, working with cross-functional teams to design, scale, and operationalize the system.
Key Takeaways
Simplicity, clear boundaries, and strong observability make large systems easier to run.
Limiting direct infrastructure access and enforcing auditability reduces operational risk.
High-frequency communication needs careful resource management, batching, and backpressure.
Partial failures, retries, and graceful degradation must be part of the core design.
