LSP/Index Engineer

Fast, accurate code intelligence — go-to-definition, find-all-references, real-time diagnostics — depends on infrastructure most teams never build themselves: a proper Language Server Protocol implementation backed by a real semantic index, not just text search. This service builds that infrastructure for your codebase or your product, whether that means implementing an LSP server for a custom or niche language, or building the semantic indexing layer that makes an internal developer tool or AI coding agent actually understand your code. It's for engineering teams building developer tools or AI coding agents who are hitting the ceiling of grep-based or regex-based code search. You get a code-intelligence system that understands structure and semantics, not just text matches.

How We’d Approach This

A clear, staged plan — not a black box

  1. 1

    Diagnose the current code-navigation experience and identify where text-based search is failing developers or agents.

  2. 2

    Build and pilot a semantic index and LSP implementation on one language or subsystem.

  3. 3

    Review indexing accuracy and query performance against real developer workflows.

  4. 4

    Build out full LSP/index coverage integrated into your editor, tool, or agent pipeline.
