Vincent Fearing

About

Full-stack engineer with deep experience in high-stakes integrations: owned end-to-end fintech payment notification/installment tracking at an early-stage startup (FastAPI/React/AWS), including multi-environment routing for live banking partners and reliability patterns like idempotency and retries. Also built a Coachella partner ticketing platform (React/TS/Node/Postgres) with strong concurrency controls and zero-downtime migrations, and previously delivered media-asset ETL/file-sharing automation at Sony Pictures using Frame.io with checksum-verified transfers.

Key Strengths

• End-to-end ownership of production features (frontend, backend, deployment/ops)
• Fintech/payment systems expertise (installments, confirmations, notifications, reconciliation)
• AWS production operations with multi-environment management (dev/sandbox/prod) for live banking integrations
• Reliability engineering for external APIs (idempotency, retries, defensive coding, detailed logging)
• Maintainable integration architecture via adapter pattern; reduced partner onboarding from many code changes to a single module
• Zero-downtime migration strategy (expand/contract with staging validation and low-traffic cutovers)
• Strong data integrity approach using Postgres constraints + transactions to prevent race-condition over-allocation
• Measurable production optimization: reduced USIO confirmation log noise from 800+ entries to targeted batches, improving incident response time
• Built robust media asset ETL pipelines with checksum validation and idempotent syncing across post-production teams
