ABOUT UJJWAL SINHA

I design and build intelligent cloud systems that power real world airline operations. My work focuses on scalable, event driven architectures on AWS that process high volume data across ticketing, PNR flows, and operational platforms.With a strong foundation in serverless technologies and real time data pipelines, I enjoy turning complex airline problems into reliable, cost efficient cloud solutions. Alongside this, I am actively integrating Generative AI into backend systems to create smarter workflows, conversational interfaces, and data driven automation. Professional ExperienceI currently work with a leading Canadian airline through Tata Consultancy Services, where I build and scale operational data platforms that handle critical airline data in real time.My responsibilities include designing microservices in Node.js, building event driven pipelines using AWS Lambda and Kafka (MSK), and ensuring high reliability across distributed systems. I also focus heavily on monitoring, performance optimization, and system resilience.🧠 GenAI & Intelligent SystemsI am deeply interested in how Generative AI can be embedded into real production systems. This includes AI powered search, conversational experiences, reasoning over structured airline data, memory based personalization, and RAG driven knowledge systems.My goal is to make AI a core part of system architecture, not just an add on feature. Technical SkillsAWS Lambda, DynamoDB, S3, SQS, SNSAmazon MSK (Kafka), Kinesis Data StreamsAWS CognitoCloudFormation and infrastructure automationNode.js microservices and real time processingGenAI integrations and LLM based workflows What Drives MeI enjoy working on high scale systems where performance and reliability truly matter. The airline domain constantly pushes engineering excellence, and I love combining that with modern cloud and AI technologies to build the next generation of intelligent platforms.
