About
Staff Software Engineer & Systems Architect | Ex-Google, Twitter, Goldman Sachs
About Me:
Hi, I'm Reinaldo. Over the past 15+ years, I've designed and scaled systems that handle planetary-level traffic. As a former Staff Engineer at Google and Twitter, and a Managing Director at Goldman Sachs, I specialize in building highly resilient distributed systems, search ranking algorithms, and large-scale data pipelines.
Throughout my career, I've patented social graph algorithms and led engineering teams at the highest levels of Big Tech and finance. I enjoy breaking down complex architectural problems and helping engineers level up their technical and strategic thinking.
I can help you with:
* System Design & Architecture: Mastering large-scale distributed systems, indexing, NoSQL databases, and MapReduce paradigms.
* Search & Data Science: Deep diving into search ranking algorithms, information retrieval, and scaling data processing.
* Core Technologies: Writing production-grade, highly optimized Python and JavaScript.
* Career Growth & FAANG Prep: Navigating the challenging path from Senior to Staff/Principal, mastering Big Tech system design interviews, and thriving as an engineering leader.
Whether you are looking to ace a high-stakes interview, architect a complex data pipeline, or strategically navigate your career progression, I'm here to provide actionable, proven guidance. Let's build something great together!

What happens when you start
You tell Reinaldo your goals. They see exactly what you want to work on before session one.
You meet within days. Reinaldo reviews your application and books your first session, usually within a day or two.
You leave with a plan. Concrete next steps and a weekly rhythm from your very first week.
