Experience

Lead Software Engineer · Gamma

2023 – 2025 · Remote
  • Led a team of five engineers to develop a 0 to 1 product feature that integrated a new channel (WhatsApp) into a multi-channel contact center. This required design changes across the entire stack, team management, and collaboration with other teams.
  • Set up a performance testing environment for the migration from on-prem to AWS, simulating over 4k phone calls per second. It helped detect performance issues early on, which were crucial for the migration to AWS.
