Projects

Built and maintained a shell-driven Android optimization toolkit for rooted devices, focused on runtime tuning, repeatable tweak workflows, and easier long-term maintenance.

Implemented a native C++ root module that applies CPU affinity, scheduler policy, and I/O priority to critical Android system tasks with low-overhead boot-time execution.

A URL shortener with click analytics, geo-IP lookup, and a write-heavy cache layer. Designed to handle viral-link hot-key scenarios without melting Redis.

A per-tenant API gateway built around atomic Redis Lua token buckets, plan-aware quotas, per-route cost weights, and standard X-RateLimit response headers.
