## Profile

**Applied AI & Backend Developer**

I build AI workflows for app code scanning and publishing, blog generation, and lead sourcing, backed by production Python services.

Structured machine-readable facts and source links: [profile.json](/profile.json).

## Work & impact

At Froxy Labs, I work on app code scanning and a publishing agent for app categorization, store content, and publishing profile completion in Google Play Console and App Store Connect. I also work on blog-generation workflows and a lead-sourcing engine, with evaluation and guardrails for agent behavior.

The backend connects Python/FastAPI services, validation models, PostgreSQL, Redis/Celery, asynchronous jobs, REST APIs, and WebSockets. Related product integrations include Stripe, RevenueCat, and PostHog. Delivery work includes Docker/Kubernetes, CI/CD, and automated tests.
