I build software close to the underlying machinery —
languages, compiler internals, systems software, infrastructure, and tools for developers.

Peeper

Peeper Programming Language

A programming language and compiler designed around a simple principle:

Things should work and feel the way they look.

The project spans language design, parsing, semantic analysis, type checking, ownership, data-flow analysis, drop semantics, module systems, compiler architecture, and developer tooling.

Selected Work

Ferret

Programming language compiler and language implementation project.

Bornika

Unicode-based Bangla keyboard IME for Linux.

FurrDB

In-memory key-value cache database.

Octoload

Server load balancer built around lightweight networking and infrastructure primitives.

SquirrelZip

Command-line multi-file compression and encryption tool with zero external dependencies.

FrostUI

Modern C++ GUI framework with platform abstraction for Linux/X11 and Windows/Win32.

Poketab Messenger

Self-hostable realtime messaging platform with end-to-end encryption.

Poketune

Progressive web application for instrument tuning.

Open Source

I contribute upstream when I find something worth fixing, simplifying, or extending.

Zed High-performance code editor and developer tooling.

GOCQLX CQL query builder for ScyllaDB.

D2 Declarative diagram scripting language.

Socket.IO Deno Socket.IO implementation for Deno.

Lore Version control system from Epic Games.

FreeLLMAPI Open-source tooling around accessible LLM APIs.

Engineering

The implementation matters, but so does the structure around it.

I tend to optimize for systems with:

  • explicit semantics
  • predictable behavior
  • small, understandable abstractions
  • centralized invariants
  • minimal accidental complexity
  • architecture that makes incorrect implementations harder to introduce

A question I keep coming back to is:

How should the system be structured so the next change is difficult to get wrong?

Writing
