Jose De La Rosa is a Senior Software Engineer based in New York with 9 years of hands-on experience building full-stack and infra solutions across startups and enterprise products. He combines backend, frontend, DevOps, and ML expertise—having driven major migrations, cut infrastructure costs, and lifted Next.js core vitals from 34 to 90 while introducing React Server Components and Tailwind. As a sole engineer at times, he established agentic engineering practices to manage multi-repo systems, shipped AI assistants and model classification pipelines, and modernized legacy stacks. He is an active open-source contributor, improving array utilities in the Grain language and adding CSS-module and framework integrations to Plasmic’s visual builder. Comfortable working across Go, Python, Ruby, TypeScript, and C, Jose blends pragmatic engineering with product focus to deliver measurable business value. Outside work he playfully describes himself as a "fireman developer," hinting at a knack for tackling urgent, messy problems and putting systems back under control.
