Work Experience

My professional journey in software engineering and technology

Jan 2026 — Mar 2026 · Remote

  • Architected a privacy-first vehicle lookup and alerting system using the Twilio API and Firebase, enabling users to anonymously notify owners of parking blockages via predefined WhatsApp messages triggered by license plate entry.
  • Implemented an automated time-bound escalation workflow that triggers a masked, pre-recorded audio call via Twilio if messages remain unacknowledged, ensuring prompt resolution without exposing user phone numbers.
