## About

```text
At Miratech, I built the API foundation and shell for a multi-tenant telecom portal, then owned its customer-onboarding micro-frontend: an eight-step wizard over TMF v5 APIs that can resume after a failed step. I also added runtime checks for Module Federation shared singletons and CI coverage for affected projects.

At RocketHash, I built an A/B testing framework and shipped experiments that increased registration conversion by 17% against a 10% target. I also replaced an exposed third-party API integration with an Express proxy and built a real-time recent-wins feed over WebSockets.

Previously, at Trinetix, I built a scheduling calendar for a medical platform and an SSE-based LLM chat interface. At Capgemini Engineering, I built Node.js services for automated pharmaceutical compliance reporting, cutting processing time from hours to minutes and producing more than 4,000 screenshots monthly.
