Bio

Mid-level Backend Engineer specializing in automation-heavy service platforms and operational integrations. I design and maintain production Python backends that orchestrate multi-step workflows across internal systems and Jira, with explicit runtime safety controls (preview mode, approval gates, caps, duplicate prevention, retry/backoff, and audit logs). I also build supporting data layers for operational analytics, including ETL pipelines and performance-aware processing on large datasets. Strong systems foundation in C/C++ and Rust, with a primary interest in low-latency systems.

Experience

Business Intelligence Assistant

Own backend and data automation for Services operations, including a 10-step intranet-to-Jira sync workflow covering extraction, transformation, ticket creation, post-processing, and closure.

Implemented operator-safe execution with preview runs, approval flow, policy caps, duplicate checks, summary allow/deny filtering, retry/backoff behavior, and JSONL run-history logging.
