Ruan Lopes

Backend Engineer with 10+ years of experience designing and scaling SaaS platforms and high-transaction systems. I specialize in Ruby on Rails and system architecture, building products from concept to production in both startup and regulated environments. Throughout my career, I have architected multi-tenant platforms, designed scalable database models handling millions of transactions, and delivered compliance-sensitive systems in regulated markets. I've led end-to-end backend development, built API-first architectures powering web and mobile applications, optimized performance under production load, and contributed to technical strategy aligned with business growth. Beyond code, I bring strong system design fundamentals, product thinking, and cross-functional collaboration experience across distributed teams and time zones. I’m particularly interested in scalable backend architectures, performance optimization, and long-term technical strategy in environments that value quality, ownership, and impact. Open to new challenges.
