ABOUT VATSALA SINGH

I build intelligent systems that operate at real-world scale.I’m a Senior Software Engineer with 4+ years of experience at the intersection of backend systems and AI/ML, focused on designing scalable platforms and bringing LLM-powered applications into production.Currently at Oracle, I’m working on AI-native Electronic Health Record (EHR) systems used across hospitals and healthcare facilities globally. My work involves building distributed systems and FHIR-based APIs, while integrating LLMs and agentic workflows to simplify how physicians interact with clinical data - improving productivity by up to 30%.Previously at Walmart Global Tech, I contributed to large-scale marketplace and personalisation platforms serving 200K+ sellers, 420M+ items, and 120M+ users. I built systems that directly drove business impact- including reducing seller onboarding friction by 40% and enabling 35% catalog growth — while also developing AI-powered experiences like smart product discovery and internal RAG-based knowledge systems.What I bring:• Strong foundation in backend engineering: Java, Spring Boot, Microservices, Distributed Systems, REST APIs, GraphQL• Hands-on experience with AI systems: LLMs, NLP, Retrieval-Augmented Generation (RAG), Agentic Workflows, LangChain• Proven ability to take systems from idea → production with measurable impact• Experience optimising performance (35% latency reduction) and improving reliability (15% MTTR reduction)What excites me:I’m particularly interested in building AI-native systems — where large language models, data, and scalable infrastructure come together to solve real-world problems.From automating clinical workflows to enabling intelligent search and developer productivity tools, I enjoy working on problems where AI doesn’t just assist, but fundamentally transforms how systems operate.I’m always open to conversations around AI Engineering, Backend Systems, and Applied AI.If you\'re building something impactful in LLMs, distributed systems, or intelligent platforms — let’s connect.
