Ismael Osvaldo Cedano Vargas
@ismaelosvaldocedanov
I build high-performance full-stack applications across data, frontend, and platform systems.
Dominican RepublicWhat I'm looking for
I've improved critical applications for Sun Life Financial, Rivian, and The New York Times, working across frontend, backend, data infrastructure, and delivery pipelines.
At Sun Life Financial through XTeam, I rebuilt backend data flows with Go and NestJS, migrated ETL to ELT, and reduced batch processing failures to five minutes. I also brought API response times down from three minutes to seconds and delivered an internal app ahead of schedule.
At Rivian through Turing, I helped move core modules from a monolith to micro-frontends, built Node.js middleware for authentication and data transformation, and reduced load time by 40%. I also standardized CI/CD configurations, cutting pipeline deployment time by 35%.
At The New York Times, I led React and TypeScript frontend work, supported Node.js and Express services, and helped migrate REST endpoints to GraphQL. My work reduced page loads from two minutes to milliseconds and moved Core Web Vitals metrics from red to green by more than 80%.
