I build tools that bridge AI and the long tail of language work — software for linguists, Bible translators, and language communities who don't usually get first-class tooling.

I work at SIL Global in language technology, with a focus right now on making domain-specific software agent-native via the Model Context Protocol (MCP).

FLExToolsMCP — An MCP server that lets Claude, Copilot, or Gemini write FLExTools scripts and manipulate FieldWorks lexicon data in natural language. Indexes ~1,400 LibLCM/FlexLibs functions so an AI can actually find the right call. Built in connection with SIL's AI Integration Advisory Board.

FLExToolsMCP can hanfle requests as small as:

"Replace any instance of k with c in the lexeme form" → AI generates, tests, and runs the operation.

Or as large as:

"Build for me a 2000 word sample FLEx lexicon for Swahili, complete with the necessary affixes set up the the parser with rules to handle phonological changes.

FLExTools — Python scripting utility for SIL FieldWorks Language Explorer. The host environment FlexToolsMCP targets — every module the MCP generates ultimately runs here.

Prestige — A desktop + PWA player for Basic Oral Language Documentation (BOLD) corpora. Loads a SayMore session, shows synchronized video + multi-track waveforms + ELAN annotations, and runs offline so community teams can share oral histories without installing dev tooling. Background paper (PhD defense).

Keyman — Open-source cross-platform keyboard input system supporting 2,000+ languages across Android, iOS, Windows, macOS, Linux, and the web. I contribute validation and parsing tooling and have been making the ecosystem AI-assistable.

Keyboard App Builder — SIL tool that wraps Keyman keyboards into branded Android apps so language communities can publish their own keyboards on Google Play. (Repo is private; link goes to the product page.)

• flexlibs — Python library for FLEx projects. My v2.0 rewrite adds comprehensive Operations classes (CRUD APIs organized by FLEx domain: Grammar, Lexicon, Texts & Words, Notebook, Lists, System), and v2.2 Wrapper Classes + Smart Collections that handle polymorphic FieldWorks types automatically — no more manual ClassName checks or casting. ~1,400 functions, fully backward-compatible with v1.x. This is the foundation FlexToolsMCP indexes.
• KeymanMCP & ParseKB — Making Keyman keyboard development AI-assistable; parsing and converting between keyboard formats.

• MCP servers for specialized software — FLEx, Keyman, and other tools whose user base is small enough that generic LLMs don't know the API surface.
• Bible translation & Scripture engagement — Paratext, FLEx, lectionaries, versification.
• Linguistics & phonology — phonetic transcription, distinctive features, oral corpora.
• Lots of Python, increasing TypeScript, plus whatever the host application speaks (C#, Pascal, XSLT).
