Identified and fixed a search performance bottleneck where every keystroke triggered a full O(n) buffer scan from row 0. Implemented incremental result filtering in SearchAddon.ts and SearchState.ts β€” when a user extends a search term (e.g. "hel" β†’ "hell"), existing results are now filtered instead of re-scanning the entire terminal buffer, eliminating the 2.5s+ input delay on every keystroke.

Let's work together

I'm open to full-time roles, contract projects, and collaboration. Whether it's a complex full-stack system, an AI-powered product, or a challenging engineering problem β€” let's talk.
