## What I'm looking for

```text
I'm looking to build and operate production backend and AI inference systems, owning reliable services from design through deployment, observability, and iteration on real user needs.
```

## About

```text
At AppFox, I own 10+ ASP.NET Core microservices serving live production traffic, including gateway, identity, inventory, store, and orchestration services. I reduced API latency by up to 50% through hot-path optimization, query tuning, Redis caching, and response aggregation.

Previously at Valletta Software Development, I designed and operated an HRTech SaaS AI inference layer using Semantic Kernel, Google Gemini, embeddings, and vector retrieval. I made model behavior observable and auditable with PII-safe data handling, operation logging, rationale tracking, and retry and failure handling.

I've also built high-throughput telemetry ingestion and real-time operator control systems at Empire of Bloom. I take products from discovery and schema design through deployment, production metrics, and iteration on real usage.
```
