Luis Felipe Fernández Betancur

I’m a backend developer building high-demand systems with PHP/Laravel, focused on scalable architectures, reliability, and measurable performance gains. With 3+ years of experience, I specialize in multi-provider integrations and production-ready automation for B2B platforms.

In B2B travel search and booking, I integrated and certified 28+ international providers across 7 categories, scaling the platform from 5K to 50K searches/day without degradation. I improved latency from 8s to 1.2s (85%) and reduced query volume from 150 to 12 (92%) by restructuring API usage and caching.

I also delivered large-scale data engineering: unified 1M+ hotels using Levenshtein + Haversine to reduce duplicates from 30% to 5%, and built pipelines for 5M+ images with 40% storage savings. My multi-level Redis cache reduced API calls by ~70%, while circuit breakers and retry logic cut errors by ~40%.

Beyond core services, I automate intelligence with AI—using Apify for scraping plus OpenAI API sentiment analysis to generate a 0–100 Hotel Intelligence Score with real-time destination comparison. I’ve worked on regulatory-compliant subscription and verification systems, mentored junior developers with daily code reviews, and value documentation and clean, maintainable code.
