Proof of Work
Multi-File Codebase Indexing & Semantic Agentic Refactoring
Engineered local embedding and symbol graph pipelines capable of indexing hundred-thousand-line monorepos into contextual embeddings, enabling multi-step agentic software modifications.
Context budgets require strict retrieval pruning in repositories with dense circular dependencies.
Context: Custom tree-sitter chunking, semantic vector index, agentic terminal command execution loop.
View missionCursor Speculative Code Editing & Shadow Workspace Architecture
Architected Cursor's instant-apply and speculative editing engine, which runs isolated shadow syntax trees to predict multi-token keystrokes and merge large diffs into production codebases with zero visual latency.
Requires real-time AST parsing and language server protocol (LSP) indexing to ensure semantic validity of speculative edits.
Context: Custom fine-tuned small speculative draft models paired with frontier reasoning models (Claude 3.5 Sonnet, GPT-4o).
