Résumé

xenomus

Software developer · Full-stack web, game systems and developer tools

Summary

Software developer with six years of building and shipping software. I've built and run a commercial subscription platform end to end (payments, licensing API, admin tooling), led development of an online RPG, and written developer tools in TypeScript, Python, Java and C++. I'm comfortable owning a project from data model to deploy.

Experience

Full-stack developer, Subscription software platform · own product
May 2026 – Sep 2026
- Built the storefront, accounts and licensing API for a paid desktop app in Next.js, React and Postgres (Drizzle ORM).
- Integrated card and crypto payments behind a single provider interface, with discount codes and transactional email.
- Designed device-bound licensing with Ed25519-signed JWTs for sign-in, session refresh and signed release downloads.
- Shipped an admin console (sales, refunds, bans, audit log, client error reports) and affiliate and reseller programmes with payouts, API keys and webhooks.
- Wrote a Discord bot that links accounts and reconciles subscriber roles on a schedule.

Projects

Full-stack · commercial product Private

Subscription licensing platform

The storefront, accounts and licensing backend for a subscription desktop app, plus the Discord bot that keeps member roles in sync with subscriptions.

How it's built

Next.js 16 and React 19 app with Better Auth (verified email sign-up) and Drizzle ORM on Postgres.
Card and crypto checkout behind one PaymentProvider interface, with discount codes and transactional email.
The desktop client signs in, refreshes sessions and downloads signed releases through an API secured with Ed25519 JWTs; licenses are device-bound.
Admin console for sales, refunds, grants, bans, an audit log, client error reports and per-product status.
Affiliate and reseller programmes: click and conversion tracking, payouts, sub-resellers, API keys, webhooks and white-label launcher themes.
Discord bot links accounts with short-lived JWTs and reconciles subscriber roles every 15 minutes.

Android app Private

Andraude

An Android app for chatting with Claude Code running in Termux, without leaving the app.

How it's built

Streams replies live, with tool calls inline and their output a tap away.
Stop, new chat, resume past sessions, model and folder picker, plus plan-usage windows under the title.
A small Python bridge inside Termux, started through Termux's RUN_COMMAND service.
Tests drive the real bridge against a fake claude, so CI doesn't spend usage.

Roblox production workbench Private

Corestack

A local-first web workbench where an AI agent takes a production brief and works across Roblox Studio, Blender, Photoshop and FL Studio, with every change reviewed before it lands.

How it's built

Agent runs with tool history, approve/reject checkpoints, cancellation and a record of what changed in files vs. in Studio.
Plugins for HUD design, R6 animations, NPC creation, sound effects, VFX, cutscenes and thumbnails, each driving its app over MCP.
VFX are checked with frozen-frame captures and real-time viewport recordings before they're shown.
Runs as an MCP server too, so Claude Code can be the agent.

Open-source Studio plugin

Gitmolder

Syncs Roblox Studio with GitHub repositories, so you can use git without Rojo or any external editor.

How it's built

Pushes every changed script in one commit: builds a single tree with the Git Data API, then commits and moves the branch ref.
Skips unchanged scripts using FNV-1a hashes, so a push only uploads files that actually changed.
Throttled worker pool (~25 requests/sec) for parallel uploads and downloads, with progress and cancel.

Web tool

Dialogue Nodes

A visual editor for building NPC dialogue trees, exported straight into a game as a Lua module.

How it's built

Imports and exports Lua module tables, so graphs go straight into a game's dialogue system.
Multiple NPCs per project, with options, auto-advance, quest triggers and condition-based starter redirects.
Built-in validator and a chat emulator to play through a conversation before shipping it.

Website + API Private

xenomus.dev

This site, on Cloudflare Pages, with a Cloudflare Worker that pulls live player counts and visits from the Roblox API.

How it's built

The stats worker resolves place ids to universes and returns totals, per-game stats and icons in one request.
GitHub activity on this page comes from a sync script; CI tests, type-checks and deploys on every push.

Cold Call Simulator

UI & gameplay systems · team of 2 with @ineternet · 72 hours, Feb 6–9 2026

A cold-calling game played on a fake desktop OS. Built in 72 hours and awarded an honorable mention out of 500+ submissions.

The desktop window manager: draggable app windows, focus and z-ordering, a taskbar, and UI that scales with the viewport
The client game loop and in-game mail: boss emails, read states, popups and per-email actions
The boot sequence: preload, fan audio, and the reboot at the end of each shift
Co-built the voice-call app (push-to-talk mic through Roblox's audio API, call timer, hang-up flow) and AI-generated leads
