I'm contributing to Insforge and Logto open-source projects, building reliable full-stack and backend capabilities. At Insforge, I expanded S3 gateway operations including CORS, object tagging, and bucket versioning while strengthening AWS constraint validation and memory safety.

I engineered composite foreign-key support across an API and dashboard, replacing single-column limits with multi-column mappings for complex schemas. I also refactored a 24-case S3 gateway switch into an exhaustive registry map, reducing routing boilerplate by over 60%.

At Logto, I refactored multi-query authentication workflows into atomic transactions, removing explicit row and table locking during concurrent runs to improve backend throughput and reliability.

I've also built a decentralized voting platform with React, Spring Boot, PostgreSQL, Web3, and Ethereum; a concurrent Java load dispatch service; and an automated LinkedIn alumni data pipeline backed by PostgreSQL. My work centers on secure APIs, authentication systems, database design, system performance, and scalable web application architecture.
