Daisy Oliani

Full-stack developer, I design and develop web applications and complete digital products, from defining the need to deploying in production.

I can assist you in creating or evolving:

a SaaS application or a business platform;

a high-performing and responsive website or landing page;

interfaces with multiple user profiles, authentication, and dashboards;

features integrating artificial intelligence;

multilingual products;

a clear, maintainable, and accessible front-end architecture.

I primarily work with React, Next.js, TypeScript, Node.js, Ruby on Rails, PostgreSQL, and Tailwind CSS. I value code quality, user experience, visual consistency, performance, and product goals equally.

I have notably designed and developed Practice-BR and Practice-FR, two EdTech platforms used by real teachers and learners, with role management, interactive exercises, automatic grading, dashboards, progress tracking, automated tests, CI, and production deployment. I also created the website for LeCLUB Fitness & Wellness, a Next.js landing page designed to present a premium brand and convert visitors into leads.

My experience in training and instructional design constitutes an additional specialization for EdTech, e-learning, and user experience projects, but I can work on any type of digital product.

Do you have an idea, a product to structure, or an application to improve? I'll help you transform it into a clear, reliable, and truly usable solution.
