Hi there! 👋 I’m Rajat Kumar Dabas, a Software Engineer at Paytm and B.Tech Computer Engineering student at Delhi Technological University (DTU, 2025). I specialize in backend development, distributed systems, and AI-driven automation — building scalable and reliable software that powers real-world impact. My tech stack includes Java, Spring Boot, Python, LangChain, RAG, MCP, Kafka, RESTful APIs, gRPC, Protobuf, MySQL, Postgres, Redis, Elasticsearch, Kubernetes, AWS, and CI/CD pipelines. At Paytm, I’ve: Engineered AI-powered MCP servers and chatbots with LangChain + OpenAI, cutting API dependency by 99% and automating internal workflows. Built multi-tier rate-limiting architectures in Java/Spring Boot with Kafka-based consumer segmentation, sustaining 10x traffic surges with 99.9% uptime. Migrated high-traffic APIs from JSON → Protobuf, reducing payload size by 35% and improving latency by 15%. Beyond work, I’m passionate about competitive programming and algorithmic problem-solving, achieving: 🧠 LeetCode Knight (1850+), Codeforces Specialist, CodeChef 3★. My interests span backend engineering, cloud computing, AI integration, microservices architecture, and data infrastructure — and I’m always eager to collaborate on innovative, large-scale projects that push system performance and intelligence further. Open to Software Engineer, Backend Engineer, and AI Engineer roles — both remote and global. Outside of coding, I enjoy reading biographies, exploring new AI tools, and playing football or badminton to recharge.
