Architecture

Implemented backend changes for large-scale SaaS data movement while preserving safe read/write behavior.

Migration safety

Designed phased state-machine flows with fallback paths and tenant-level rollout control.

Reliability

Delivered failure classification across production workflows, improving visibility into retryable and permanently failed items.

Observability

Expanded structured error-code coverage and standardized retry-history models with attempt-level status, error code, and data-size context.

AI engineering

Built a Claude-powered debugging agent that uses issue context, log signals, database context, and RCA patterns to produce fix plans.

Enablement

Created setup guides and knowledge-transfer sessions so engineers could adopt AI-assisted debugging workflows independently.

Operations

Built monitoring for onboarding and production health signals, and supported reliability work across multiple cloud workloads.

Contribution

Contributed to the transition from a legacy PHP monolith to scalable backend microservices.

Contribution

Improved maintainability and supported faster deployment cycles through service decomposition.

Contribution

Worked across SaaS product workflows, backend APIs, data persistence, and operational diagnostics.

Contribution

Supported backend workload monitoring using CloudWatch, Grafana, and Kibana.

Contribution

Analyzed logs, helped identify recurring production issues, and partnered with engineers on fixes and release coordination.
