At Lyftr AI, I developed an end-to-end agentic appointment booking system integrated with Google Calendar, including slot generation, booking workflows, and reminder scheduling.

I also designed a multi-stage LLM-powered spam detection pipeline with Inngest. Its event-driven, non-blocking workflow kept spam analysis from delaying core AI replies.

At Lyftr AI, I increased dashboard performance by 40% through SQL query optimization and improved data access patterns. I also built end-to-end Meta Embedded Signup onboarding, integrating Meta Graph API for WABA provisioning, WhatsApp coexistence, and retry handling.

At Good Guys, I automated marketing and sales workflows and integrated Zapier, Zoho services, and Brevo. I also built Toshu, a CLI-based task management tool with a FastAPI-powered web interface.
