At Younea S.à r.l., I took LetzChat V2 from its first commit to production launch as the lead and effectively sole developer. The multi-tenant WordPress SaaS platform supports AI chat and voice calling, with white-label deployments, usage-based billing, and feature flags.
I built a headless Python worker for usage events and signed billing webhooks, plus a separate async network service with a versioned REST API. I also developed the React and TypeScript admin SPA over a PHP service layer.
For LetzChat V2, I created an automated evaluation suite to test chatbot grounding, hallucination refusal, response language, and tool use. I also handled release operations across environments.
At Dextern, I led zero-downtime migrations of e-commerce platforms from Magento 1 to Magento 2 and BigCommerce while keeping third-party integrations working. I also built a Vue.js SaaS product and automated deployment pipelines that cut deployment time from hours to minutes.
