At Newshore Technologies, I led the Avianca next-generation Check-in platform on Navitaire, designed for about 130,000 daily users. I designed 12 business APIs using DDD, CQRS, and Clean Architecture, and the domain model redesign improved response quality by about 70%.

I also consolidated three repositories into one monorepo, cutting duplicated code by about 20%, and contributed to migrating backend services to .NET 8. Across the airline platform, I designed reusable multi-PSS architecture and NUnit integration testing that unblocked other teams; on Avianca Check-in, bugs per sprint fell from 13 to 5.
