Himanshu Singh — Software Engineer

SDE with 10+ years of experience building high-impact, scalable Web & Mobile platforms across Amazon, Walmart, Delivery Hero, and McKinsey. I specialize in architecting modern JavaScript/TypeScript applications (React, React Native, Node.js) and also bring solid backend development experience with Java, microservices, and distributed systems. At Amazon and previous roles, I’ve led engineering for complex platforms — from server-driven UI systems that drastically reduced release cycles, to enterprise-scale retail and logistics solutions used globally. I focus heavily on clean architecture, system design, performance optimization, and building reliable CI/CD pipelines. I also have hands-on experience with AI and Generative AI use cases, including: • Building LLM-powered features using Amazon Bedrock • Designing AI-assisted workflows for automation and developer productivity • Applying embeddings, vector search, and prompt engineering for real-world apps • Integrating AI models into production-grade React/Node systems On the cloud side, I am proficient in architecting and operating solutions on AWS, with experience using: Lambda, S3, DynamoDB, CloudFront, API Gateway, SNS/SQS, CloudWatch, ECS, IAM, and IaC practices. I’ve set up complete infrastructures for mobile & web applications, including observability, cost optimization, and secure deployment strategies. Beyond hands-on development, I enjoy leading teams, conducting design reviews, mentoring engineers, and driving engineering best practices such as TDD, performance benchmarking, and automation-first culture. I’m passionate about building systems that scale, shaping engineering strategy, and delivering products that make a measurable business impact.
