Snowmuffin — Full-stack developer
Full-stack developer with operational LLM data pipelines.
Plus sustained C# game tooling for Space Engineers. The public repos and case studies here are the evidence. Open to full-time or contract.
Skills & Expertise
Case studies
Work before you leave
Three deep-dive narratives—web + API, data pipelines and merge tooling, and long-lived game plugins—each tied to public repos and how they fit together.
GameHub
NestJS API and a Next.js-facing experience
A full-stack slice: structured backend APIs and a web surface for discovery and interaction—representative of how I ship product-shaped work end to end.
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
Complementary plugins in the same mod ecosystem
Two public plugins that solve different problems in the same game stack—grid management and event-driven behavior—showing sustained C# tooling work.
DEPTHACROSSWEB · DATA · GAMES
The features below mirror the case studies: full-stack slices, data hygiene, and sustained game tooling—plus mobile and delivery when stakeholders need them.
Full-stack web products
Repeatable pattern: bounded APIs (NestJS), typed clients, and Next.js surfaces—so features ship without tangling layers. See the GameHub case study for the two-repo story.
Data paths & merge tooling
Pipelines and small utilities that turn messy conversational inputs into portable artifacts—operational stages first, model calls second. Lacuna + convmerge on /work.
Game ecosystem plugins
Long-lived C# tooling in Space Engineers: grid workflows plus event-driven hooks that complement each other in players’ saves.
Ops you can hand off
Dockerized deploys, Nginx, Linux hosts, and several concurrent servers—enough structure that builds and rollbacks are boring.
CI/CD for mobile and web
GitHub Actions, distribution channels, and guardrails so teams spend review time on product risk—not manual release steps.
Mobile (React Native)
Cross-platform delivery with the same discipline as web: instrumentation, store readiness, and iteration loops that match business urgency.

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.
