Daniel Núñez

Ruby on Rails developer with a strong data background, I build production-grade web applications that are cleanly architected, well-tested, and easy to evolve. I’m comfortable owning features end-to-end: designing the domain model, building Rails controllers/services, shipping polished UI with modern frontend tooling (Hotwire/Turbo/Stimulus, ViewComponent, Tailwind), and ensuring performance and reliability in real-world usage.

On the data side, I bring hands-on experience with PostgreSQL and analytics-style workflows: writing efficient queries, shaping data for reporting, integrating external APIs/data sources, and building search/filter experiences that feel fast and intuitive. I care a lot about code quality and maintainability—clear boundaries, pragmatic refactors, and automated tests (RSpec) so teams can ship confidently.

I can help teams deliver high-impact Rails features, improve data pipelines/reporting, and turn messy requirements into simple, dependable software. I value direct communication, predictable delivery, and leaving the codebase better than I found it.
