I focused on driving engineering efficiency and automation improvements at TikTok, achieving remarkable results.

• Developed internal tools in Go, increasing test automation coverage to 70%.

• Established a new test infrastructure, cutting regression execution time from 2 days to 2 hours.

• Built a service that leverages LLM to summarize system alerts, enhancing alert management efficiency.

• Led performance testing for a high-traffic payments application, preventing critical revenue loss during peak holiday seasons.

Worked on firming up the testing infrastructure for the prod infra team which is the backbone of the product.
