Rajat Chaudhary — Senior Software Engineer
Backend & Data Engineering | 9+ Years | Startup-First | Scalable Systems | Event-Driven Architectures Software Engineer with 9+ years of experience in building scalable backend systems and data platforms—primarily in high-growth startup environments. My expertise spans backend development, data engineering, and system design, with a strong track record of building complex systems from scratch, leading product-critical initiatives, and driving architectural improvements across teams. Over the years, I’ve designed and implemented RESTful APIs and microservices, built batch and real-time ETL pipelines, set up distributed databases and data warehouses, integrated ML workflows into production, and managed infra and DevOps using modern tooling. 💡 Highlights of My Journey 🏥 DaaS Platform for Medical Data: At my first company, I co-created a Data-as-a-Service platform that exposed curated medical data (CTs, publications, congresses, etc.) through public APIs—reducing server costs by 40% while unlocking a new revenue channel. 🛍️ Widget Platform at Konigle: I built a dynamic JavaScript plugin platform that allowed e-commerce sellers to inject smart widgets on their sites for pricing nudges, alerts, and conversion boosts—all without engineering effort. 📈 High-Scale Systems at Koo: At Koo (a Twitter-scale social app), I developed highly available backend services for analytics, media uploads, and kafka sinks — designed for scale, fault-tolerance, and low latency. 🤖 In my current role: Building AI-powered B2B platforms using event-driven architectures. I work on ETL pipelines, OLAP (Snowflake), analytics systems. 🛠️ Tech Toolbox Python · Node.js · Postgres · Redis · Snowflake · Clickhouse · Kafka · Airflow · DBT · MongoDB · Docker · Kubernetes · AWS/GCP · CI/CD · TypeScript · Event-Driven Systems · OLAP/OLTP · Flink I thrive in environments that demand clarity, speed, and ownership.
