- 🏗️ I design, build and operate production SaaS platforms end to end, solo — schema, backend, frontend, integrations, infra, monitoring.
- 💼 Founder of IFindSpec / Avocățescu (practice-management SaaS), StoryFuze (content creation & multi-channel publishing), Event Creator Hub and WeddingPages.
- 🤖 I build LLM agents that act on real business data — tool calling with RBAC and human-confirmed writes, messaging bots with autonomy levels, speech pipelines — and measure them with evals.
- 🧰 I also run my own agent development infrastructure: router → orchestrator → sub-agents with gates and cost-aware model routing, plus an autonomous healer.
- 🔐 Security-minded by default: prepared statements, CSRF guards, ownership checks, least-privilege keys, self-run IDOR/SQLi audits.

| Repo | What it shows | Results |
|---|---|---|
| tool-calling-agent | Tool registry with 3-point RBAC, writes as human-confirmed proposals, router with circuit breaker, metering, MCP server | 40 evals × 4 models: 88-98%, RBAC refusal 100% |
| autonomy-levels-agent | WhatsApp-style agent: off / suggest / auto, customer-confirmed writes, server-side identity, dedup and loop guards | Prompt injection resisted 100% on 4 models |
| speech-pipeline-bench | Provider-agnostic STT/TTS, transcript-based video editing, RO/EN benchmark | Whisper vs Scribe vs Gemini vs Google vs OpenAI: WER, cost, latency |
| server-update-agent | Weekly patching agent for my production server: policy decides (7-day soak, follow-up patch, human approval for minors), backup → test → prod with auto-rollback; the LLM only summarises changelogs | Rollback drill 5/5 restored in ~1 s each, 0 HTTP 5xx |

Most of my work lives in private, commercial repositories — the numbers above include private contributions.
- Pragmatic over fashionable — framework-free PHP where it's fastest to ship, Node microservices where they fit (media, PDF, queues).
- Own the whole lifecycle — test env → lint → functional checks → production, with backups and rollbacks; public repos run CI with offline eval replay on every push.
- Observable by default — metrics, logs and alerts (Prometheus, Loki, Grafana → Telegram) on everything I run.
