About

Welcome to my personal page. I'm glad you're here.

I work as a software engineer, with 10+ years of experience in building data platforms, ETL infrastructure, ML tooling, observability, etc.

My technical interests broadly fall into three clusters:

Programming language design, declarative / query languages, relational data modeling, incremental view maintenance, db internals / vectorization, data oriented design, ...
Distributed systems (particularly distributed data systems) - performance optimization, design principles, unusual theoretical approaches, etc.
Tools for Thought, end-user programming, "the computer as a bicycle for the mind", and how AI can help us out there

I write about some of them here.

At heart, though, I just love building software that is clean, performant, innovative, and pleasant to use.

Projects

Elysium

Playground

Typescript · programming language design · incremental view maintenance · app development

A reactive, relational data-centric query language and app development framework - a high-level language for building data-oriented apps, that compiles to JS, featuring an event-sourcing model and incremental view maintenance. Inspired by Differential Dataflow / DBSP, Elm, Mint-lang, Riffle, SolidJS, others. Under active development.

Nous

Tauri · Rust · OpenAI / Anthropic APIs · RAG

An AI-enabled local-first journaling and task management app, built with Tauri / React / ProseMirror and SQLite, Claude and local LLMs, and a custom sync engine plus an MCP and sync server in Python with FastAPI. Uses RAG workflows and agentic tools to incorporate contextual understanding and proactive reminders.

froglang

Rust · compiler design

An experimental programming language, compiler, and runtime in Rust. Building it has been as much about understanding compiler and runtime design from the inside as about the language itself.

Reading list

I keep a reading list of papers, projects, and ideas I find interesting — distributed systems, logic programming, query languages, serverless compute, software performance. It's a reasonable map of how I think about the problem space.
