Full-Stack Developer

Nathan Risacher

I build apps and run the infrastructure behind them.

I design, build, and ship full-stack applications — from React Native mobile apps to Next.js SaaS products. I also run the infrastructure they live on: a 3-node Proxmox homelab with 25+ containers, Cloudflare tunnels, automated monitoring, and CI/CD pipelines. I care about owning the whole stack, not just writing code that runs on someone else’s platform.

Featured Work

Inbox Sentinel

SaaS email classifier that sorts your inbox with AI

Hybrid classification engine — rule-based system handles the majority of emails for free users, Claude Haiku picks up ambiguous cases for Pro. Batch API calls classify up to 20 emails per request, cutting AI costs ~90%. One-time $14.99 purchase via Stripe, not a subscription.

Powerhouse Fitness

Mobile fitness app with 900+ exercises, AI coach, and subscription billing

React Native/Expo with Firebase RTDB for offline-first sync. RevenueCat handles subscriptions across free/Pro tiers. AI routine generation calls Claude via a webhook relay on the VPS. Custom LoRA-trained avatar “Marcus” generated with Flux.1 Dev on Replicate.

ClaudeVault

Self-hosted agent workspace with real-time Claude response loop

FastAPI + PostgreSQL + Redis backend in Docker. A watcher service on a separate host polls for dashboard messages, spawns claude -p, and posts responses back to the feed. HMAC-signed webhooks with retry and auto-disable push events to n8n, which routes to Discord. Memory files auto-sync on git push via post-receive hooks.

The Lab

3 Proxmox Nodes
25+ Containers
16 Docker Services
33 Proxy Routes
99.9% Uptime

Three bare-metal Proxmox nodes, a Docker VM, and a Hetzner VPS — all stitched together with Cloudflare tunnels, Nginx Proxy Manager, and AdGuard DNS. Automated health checks run every 4 hours via n8n and Playwright, with auto-remediation and Discord alerts. CrowdSec handles intrusion prevention across the cluster.
