||
## Summary
|
||
|
||
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 Engineer | 2025–Present
|
||
|
||
**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
|
||
|
||
**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
