Millions of Client Records

30% Increase in User Activation Rate
Improved user activation by ~30% through targeted onboarding, activation checklists, and contextual product guidance.

Architecture

Lead Email
Designed the inbound email pipeline: AWS email infrastructure receives and stores messages before asynchronous processing and LLM-based lead extraction. Later added retries, clearer failure visibility, and model migration support.

AI-Generated WhatsApp Tasks
Designed and scaled a system that extracts daily actionable tasks from WhatsApp conversations across thousands of WhatsApp Business profiles. Evolved the processing flow as production bottlenecks emerged.

Production

Meta CAPI
Built and updated the integration across multiple vendor API versions, including asynchronous event processing, deduplication, migrations, and recovery from production failures.

Security & incidents
Fixed XSS and access-control vulnerabilities. Investigated and mitigated abusive traffic and DDoS incidents using Cloudflare controls.
