Ben Aouicha

Senior Backend Java Engineer with 3+ years of production experience building scalable applications with Java, Spring Boot, and MongoDB. I specialize in performance optimization — I reduced a critical production function's execution time by 95% (from 5s to 60ms) through deep query analysis and refactoring. I also designed a dynamic MongoDB search/filtering engine from scratch, offering SQL-like expressiveness over document collections, and automated backup systems with scheduling and email reporting. Async-friendly, remote-ready, and available for fixed-price gigs or hourly engagements. Payment in USDT.
