Publications

Retargeting Managed Runtimes to Serverless WebAssembly: A Case Study in Java on Cloudflare Workers

September 2026 | Sole author | 10.6084/m9.figshare.33941974

  • Published on figshare and Zenodo under CC BY 4.0, artifact pinned to bytebox v1.0.2 at a specific commit
  • Findings from differential testing against a real JVM: startup tracks executable WebAssembly rather than uploaded bytes (a bundle grown 640-fold with inert padding kept startup flat); the documented CPU limit is not the enforced one; 5 of 14 third-party Java libraries run unmodified
  • Semantic agreement is not operational equivalence: a correctly translated regular expression cost 14 ms on the reference JVM and 11,010 ms on the host engine for identical output
  • Published and citable, not yet refereed; seeking an arXiv endorsement, with a JOSS resubmission due February 2027

Projects

Drupflare

2026 - Present

  • Drupal 11 running on Cloudflare Workers, with PHP 8.5 compiled to WebAssembly inside a Durable Object and that object's own SQLite as the database
  • No VPS, no container, no origin server, and no PHP extensions dropped to make it fit
  • Thirteen repositories, most of which stand alone: a Drupal database driver, a Workers compatibility layer, a wasm-interpreter runtime, a deployment CLI, a PHP HTTP stream wrapper, a dependency-free tar extractor, and a documented SQLite layer for Durable Objects

phasm

2026 - Present

  • A statically linked PHP 8.5 interpreter compiled to WebAssembly for the workerd runtime
  • Built because every published php-wasm build uses dynamic linking, whose linker synthesizes trampolines at request time, which workerd forbids; that makes PHP extensions unloadable and Drupal impossible
  • Ships dom, xml, SimpleXML, mbstring, and gd inside a compressed worker bundle

gmux

2026 - Present

  • A real Linux kernel running inside one Cloudflare Worker deployment, each machine a Durable Object, on the free plan
  • Boots to a BusyBox shell in a 476 ms median; fork, dlopen, job control, signals, sockets and System V IPC pass deployed
  • A 1 GiB pipeline finishes exactly across five free-plan events; a booted machine checkpoints mid-job, survives eviction and restores exactly
  • Unchanged x86-64 binaries run through Katybug, an ELF translator, matching native Linux on 117 of 117 transcript lines
  • An unmodified BusyBox httpd serves behind the site, with response bodies equal to native Linux in 6 of 6 cases

Drift

2026 - Present

  • Why does it pass here and fail there? Captures an environment as a hashed capsule, ranks what differs between a passing run and a failing one, and re-derives every verdict from the archived case
  • Kotlin Multiplatform, with 88.4% of its lines in common code and a portability atlas of 38 programs recorded on 13 Kotlin targets
  • Publishes its weak result beside the strong ones: the right cause ranks first in 19 of 41 scenarios where random order expects 15.2

burrow

2026 - Present

  • Arbitrary WebAssembly supplied at request time, on a runtime that forbids request-time code generation
  • Ships an interpreter compiled to wasm, so a guest module arriving with a request is data rather than code

bastion

2026 - Present

  • A hardened environment for self-hosted workerd, as a single binary, so the stack can run off Cloudflare's network
  • One workerd process per tenant under a cgroup, real stores behind every binding, encrypted backups with a scheduled restore drill, hash-chained audit and deny-by-default egress
  • Published to npm, Docker Hub and GitHub's container registry

bytebox

2026 - Present

  • Java on Cloudflare Workers: a Gradle plugin that compiles a Java workspace into a Worker through TeaVM
  • Consumes cartridge, the wasm-interpreter host extracted from Drupflare, so one runtime host now serves two languages
  • Ships a code-coverage lane that runs Java inside workerd and reconstructs a real jacoco.xml

tinyimg

2026 - Present

  • Image decode, transform and re-encode inside a Cloudflare Worker, with no binding and no subrequest
  • Freestanding C compiled to a single wasm32 module behind a TypeScript wrapper, because workerd has no Canvas API
  • $0.05 per million transformations against Cloudflare Images' $500 per million

recess

2026 - Present

  • A "Go Outside" app: a few small prompts a day, drawn from a catalog of 120 and filtered by clock, season, weather, and history
  • No server, no account, no competition, no social graph; an on-device CLIP model, sentence embedder, and Whisper verify completions and nothing is ever uploaded
  • Built with TypeScript and Vue

smoke

2026 - Present

MyLoRA

2026 - Present

  • A self-hosted MLOps control plane for fine-tuning LoRA adapters
  • Trains on a home RTX 4070 over an SSH tunnel, driven from a Cloudflare Workers UI
  • Built with TypeScript and deployed on Cloudflare Workers

MyMCP
