About Saurabh Sethi
I’ve always been fascinated by how people find what they’re looking for, whether it’s the perfect product in an e-commerce/quick-commerce app/site or the right piece of information in a vast system. That curiosity led me into the world of search engineering and scalable backend systems, where I now thrive as an at Majid Al Futtaim Carrefour, powering retail for millions across MENA region.Over the last few years, I’ve:Built & optimized search systems (using ElasticSearch, Lucene, Algolis, Azure Cognitive Search) that serve multi-country e-commerce platforms (UAE, KSA, etc.).Owned end-to-end search relevance (ranking, reranking, synonyms, spelling correction, autosuggest, query rewriting).Shipped personalized discovery features that move the needle on CTR, CVR, and add-to-cart rates.Build resilient backend pipelines (Java, Node.js, Kafka, Kubernetes, Azure) that serve millions of daily updates with p95 latency SLAs.Experimented fast, measured rigorously (A/B testing), and tie wins directly to GMV and revenue growth.Delivered personalization features that helped millions of customers discover products faster, boosting both engagement and revenue.Partnered cross-functionally with product, analytics, and data teams to align technical execution with business impact.What sets me apart isn’t just the stack, it’s the mindset:I don’t just write code, I design systems that solve real customer problems. From tuning search relevance to optimizing multi tenant analytics dashboards.I’m constantly asking and working to make discovery smarter, faster, and more human.If you’re looking for someone who blends deep search expertise, strong backend engineering, and business impact thinking, let’s connect.I’d love to bring that mix to your team :)
