Case studies

Work before you leave

Three deep-dives: Lacuna data tooling, plus GameHub and Space Engineers plugins from the same mid-2024 – Mar 2026 SE server stack (game server now stopped; web UI under renovation).

All case studies

GameHub

Web platform for a Space Engineers server (mid-2024 – Mar 2026); under renovation

NestJS API (game_hub_nest) and Next.js UI (gamehub-next) for a Space Engineers server that operated mid-2024 – Mar 2026. The game server is stopped; se.snowmuffingame.com currently shows a coming-soon page.

Lacuna data path

Operational LLM data pipeline + a published JSONL prep library

A Prefect-orchestrated pipeline that moves heterogeneous chat / instruct sources into a single training-ready JSONL layout, paired with convmerge — the JSONL prep library it uses, published to PyPI.

Space Engineers tooling

C# plugins used with the mid-2024 – Mar 2026 SE server (grids & events)

Public C# plugin repos (SE_Grid_Manager, SE_Event_Handler) from the same Space Engineers server period as GameHub. Game server stopped Mar 2026; these repos remain the source evidence.

How I work

DEPTHACROSSWEB · DATA · GAMES

Case studies map to public repos: GameHub + SE plugins (same former server), Lacuna data path, and the GitHub project grid below.

Full-stack web products

NestJS APIs and Next.js surfaces. See the GameHub case study for the SE server web stack (mid-2024 – Mar 2026).

Data paths & merge tooling

Pipelines and utilities that turn conversational inputs into portable JSONL artifacts. Lacuna + convmerge on /work.

Space Engineers plugins

4 public SE_* repos on GitHub (Neura list), including grid and event plugins used with the mid-2024 – Mar 2026 SE server.

Hosted on this EC2

6 processes verified here: nginx, muffinstack, muffin-backend, game-hub-nest, gamehub-next, PostgreSQL. SE game server not included (stopped Mar 2026).

CI/CD

GitHub Actions appear in public repos such as convmerge (PyPI publish) and related project workflows.

LET'S GO
DEEPER

Got a half-built data pipeline or an API surface that needs hardening? Send the problem space and timeline. The case studies show how I take a repo from messy inputs to operable output — map your situation to the closest one and start there.
