About
At Cygnus, I took Trazo from product definition to a pilot-ready release as its sole developer. I own the e-signature platform end to end, using Angular, .NET, and SQL Server.
At Cygnus, I was also a core team member of KLOC, an attendance-tracking SaaS authorized by Chile's Labor Directorate and used by 5,000+ people. I built its public API single-handedly in one month and contributed to its backend foundations and core features.
At Conavicoop, I took part in migrating a legacy platform with 30+ modules and approximately 10,000 users to .NET Core. I also optimized SQL Server stored procedures, reducing execution times from up to 30 seconds to about one second.
