- Lead Data Engineer @ Blue Ridge | Ex-Jio | Mathematics and Computing (MnC) @ IIT Roorkee | Tohoku University | UiT | WorldQuant Building Next-Gen Data Platforms Transforming big data chaos into business-critical insights through innovative engineering. Currently leading the Data Platform Initiative at Blue Ridge, where I modernise legacy systems and architect scalable data solutions. Across my career, I’ve delivered measurable impact: 75% reduction in data processing time via streaming optimisations, 90% pipeline performance boost by migrating from batch to real-time, 40% improvement in Jio’s cellular network latency affecting millions across India through data-driven network optimisation, and 80% cost savings through vendor evaluation, project sign-offs, and in-house builds. As a Software/Data Engineer with deep technical expertise and several years of experience, I specialise in modern data engineering with expertise across Hadoop, SQL, cloud-native platforms (AWS, Databricks), and next-gen frameworks like Polars and Rust. My work spans real-time streaming architectures to cloud-native data platforms, gained through experience at telecom giants (Jio), supply chain leaders (Blue Ridge), and data observability platforms (Unravel Data). Big Data & Streaming: Apache Spark, Kafka, Hadoop, PySpark, Scala, Python, Rust, Polars Cloud & Orchestration: AWS, Azure, Databricks, Airflow, Jenkins SQL & Analytics: Deep experience with SQL-based technologies and analytics solutions Performance Optimisation: Built petabyte-scale systems at Jio; expert in Spark optimization, Kafka multithreading, Polars HPC, and benchmarking frameworks GenAI & Innovation: Embedding AI/ML into pipelines and exploring LLMs for automation Led cross-functional teams delivering critical data platforms under tight timelines. Mentored engineers, creating best practices that became organizational standards. Designed data solutions aligned with business strategies, driving growth. I connect with engineers, leaders, and innovators pushing the limits of data. Whether you’re scaling platforms, integrating GenAI, or building next-gen products, let’s share insights. I write on data engineering, GenAI, and emerging tech. My newsletter “Code & Compute” simplifies complex data architecture and shares real-world lessons. I believe in making data engineering knowledge accessible, helping the community stay current. Always learning and evolving with new trends in data engineering and GenAI. DM me to discuss architecture, GenAI, or collaborations. 📧 ritvik.iitr@gmail.com | topmate.io/ritvik_raj
