Senior Software Engineer Crewhu
I provide technical direction for analytics at a B2B SaaS platform serving approximately 35,000 users, covering architecture, performance, and technical proposals. I proposed and implemented end-to-end real-time notifications using SSE and Redis Pub/Sub, with company- and user-based routing from backend events to browser clients.
I reduced a critical ConnectWise analytics query from more than 18 minutes to 3.5 seconds through indexing improvements and Redis caching. I expanded integrations from two to seven platforms, built Go and Airbyte ingestion workflows for millions of records across more than 100 companies, and improved operational visibility through ETL tracking, API-permission checks, and SigNoz alerts.
I also resolved duplicate Airbyte connections caused by asynchronous retry behavior through infrastructure, timeout, and error-handling changes. I use spec-driven development and Claude Code for implementation, test generation, and AI-assisted reviews while retaining ownership of architecture and final validation.
