Full Stack Ruby on Rails Engineer

About me

Here's a LinkedIn summary optimized for Rails roles:

Full-Stack Ruby on Rails Engineer | 6 Years Building Production Platforms | AI Integration Specialist

I build production web applications that solve real business problems. Over the past 6 years, I've developed two full platforms from the ground up—IBICASA.com and True Trek—handling everything from database architecture to deployment.

What I Do:

I specialize in Ruby on Rails backend development with strong full-stack capabilities. My work focuses on building scalable APIs, optimizing database performance, automating workflows, and integrating AI features that enhance user experiences.

Recent Highlights:

- Built IBICASA.com: Production Rails platform automating real estate workflows, reducing operating costs by 33%
- Developed True Trek: AI-powered travel platform with OpenAI integration, optimized LLM latency by 80% (10s → 2s)
- Shipped AI-enabled features using OpenAI APIs, background jobs, and performance optimization techniques

Technical Stack:

Background:

Before transitioning to software engineering in 2018, I spent 5 years as a financial auditor at firms including PwC and Crowe Horwath. That experience gave me an analytical mindset I now apply to debugging, system design, and building reliable, maintainable code.

What I'm Looking For:

Backend or full-stack Rails engineer roles where I can own features end-to-end, work with collaborative teams, and contribute to meaningful product development.
