Summary
Software engineer leading reliable API and data-platform work. Builds observable services, documents operational tradeoffs
and mentors engineers through delivery and incident review.
Experience
Senior Software Engineer | Example Systems
2023-03 - Present
• Designed a PostgreSQL-backed job queue with idempotent workers and recovery tests for interrupted tasks.
• Introduced OpenTelemetry traces across API and worker boundaries so on-call engineers could isolate slow requests.
• Led design reviews for a staged migration from synchronous processing to background jobs, documenting rollback criteria.
• Mentored engineers through incident reviews and paired on regression tests for duplicate delivery and partial failure.
Software Engineer | Sample Cloud
2020-01 - 2023-02
• Implemented versioned Node.js APIs and contract tests to keep customer integrations working through releases.
• Reworked database queries after profiling production-like workloads; verified query plans before adding indexes.
• Built an accessible React console for reviewing failed jobs and retrying only the affected work.
Junior Software Engineer | Demo Works
2017-07 - 2019-12
• Developed Python import tools that preserved source identifiers and rejected ambiguous records for manual review.
• Added integration tests around CSV exports, Unicode names and date handling to prevent silent data corruption.

Projects
Queue Observatory
2024-05 - Present
Technologies: Python, PostgreSQL, Docker
URL: https://example.com/queue-observatory
• Built an independent workload simulator that reproduces worker crashes and compares retry policies.
• Published runnable test cases and design notes explaining when idempotency keys expire and how recovery is verified.
Accessible Booking Lab
