Founder & Fractional CTO | Ruby on Rails 8 Architecture | vhsotoing@gmail.com
I am the technical founder of Licitador.co, a B2B SaaS (GovTech) built on Ruby on Rails 8. My specialty lies in designing architectures capable of ingesting, processing, and analyzing complex data—such as public procurement records—and transforming it into tools that boost companies' commercial success.
I currently serve as an asynchronous technical partner for startups across Europe and the U.S.
I do not operate as a traditional developer. I leverage artificial intelligence (Cursor / Claude) to orchestrate the rapid generation of boilerplate code, allowing me to dedicate 100% of my bandwidth to the elements that truly make or break a product:
- 🏗️ Complex Data Architecture: PostgreSQL, high-volume processing, web scraping, and search engines.
- ⚙️ Performance & Scalability: Hotwire, Solid Queue/Sidekiq (heavy background jobs), and B2B workflow optimization.
- 🛡️ Security & Deployment: Rigorous PR reviews, CI/CD, and continuous delivery.
