## Summary
Backend engineer with 7.2M lines of code across 1,603 repos, operating 11 PostgreSQL databases, 230 SQLite databases, 14 Docker services, and multiple API backends (FastAPI, Node.js) serving 48+ domains through Nginx reverse proxy.
Every feature needs an API. Built 6+ production services, unified 283 databases across 5 engines, and designed data architectures that run on $80 hardware — because the backend doesn't care how much you spent on it.

## Experience
### BlackRoad OS | Founder & Backend Lead | 2025–Present
### BlackRoad OS | Founder & Backend Engineer | 2025–Present
**API Development**
- CECE API (FastAPI): Custom AI model interaction with streaming responses
- TTS API: Text-to-speech generation service
- Lucidia API (FastAPI): Application backend with Clerk auth integration
- Image generation API: 4 backend agents (DALL-E, Flux, SDXL, Together)
- Code search API: FTS5-powered search across 354 repos
- KPI collection API: 9 collectors aggregating 60+ daily metrics
**The APIs: Each One Solving a Real Problem**
- CECE API (FastAPI) — needed custom LLM interaction with personality. Built TTS generation endpoint. Runs on Pi 5 at the edge
- AI image generation API — 4 backend agents (DALL-E, Flux, SDXL, FAL) behind a single endpoint. Automatic model routing based on prompt type
- Code search engine — needed to find anything across 354 repos instantly. Built FTS5 index, sub-millisecond lookups across entire codebase
- Fleet health APIs — SSH-based probes collect metrics from every node. Powers the KPI dashboard and automated alerting
**Database Engineering**
- 11 PostgreSQL databases across 3 fleet nodes
- 230 SQLite databases (1.4 GB) for state management and agent memory
- 22 Cloudflare D1 databases for serverless backends
- 46 KV namespaces for edge caching
- FTS5 full-text search index across code and knowledge bases
**Service Architecture**
- 14 Docker containers on Docker Swarm with service discovery
- 48 Nginx reverse proxy sites with upstream health checking
- WebSocket real-time streaming for AI model responses
- SSE (Server-Sent Events) proxy for Ollama model streaming
- GitHub-to-Gitea relay for cross-platform repository sync
**Data Processing**
- Daily KPI aggregation across GitHub, Gitea, fleet SSH, Cloudflare APIs
- Power monitoring data collection (5-minute intervals across fleet)
- Distributed tracing with nanosecond-precision span tracking
- Cron-based batch processing (52 automated tasks)
**The Data: Right Database for the Right Job**
- 11 PostgreSQL for transactional data. 230 SQLite (1.4 GB) for agent memory and local state — embedded, zero-config, fast
- 23 Cloudflare D1 for serverless applications. 47 KV namespaces for edge configuration and caching. Qdrant for vector search
- FTS5 full-text search across 156K entries — the entire knowledge base is searchable in under a millisecond
