Presentation
I am a senior developer based in Costa Rica, offering a full 8-hour daily overlap with EST/CST teams. If you are tired of losing development velocity to 12-hour communication delays, I provide the real-time collaboration your sprint needs.
What I deliver to your product:
- Modern Full-Stack Mastery: Expert-level development using React, Node.js, and TypeScript to build scalable, production-ready applications.
- Data-Driven UX via A/B Testing: I eliminate guesswork in the design process. By implementing rigorous A/B testing, I use real user data to identify which UX changes actually increase engagement, reduce friction, and drive conversions. Every UI update is backed by statistical significance, ensuring your product evolves based on what users actually do, not just what they say.
- Performance Optimization: I focus on building high-speed, responsive interfaces that keep users in the "flow," reducing bounce rates and improving overall satisfaction through technical efficiency.
- Professional Reliability: I prioritize English-first communication, thorough documentation, and a "Proof of Work" approach that keeps stakeholders informed and confident
