About

Over the past decade, I've developed software across various sectors such as Governance, E-Commerce, Video Streaming, and Electric Vehicles, among others. My focus has primarily been on Backend Engineering and Data Engineering, allowing me the privilege to tackle intricate technical challenges on a international scale. I have expertise on various technologies, including Java, Python, AWS, Azure, and a range of database systems including RDBMS (MySQL, PostgreSQL) and NoSQL (MongoDB, Scylla). Additionally, I'm proficient in tools such as Redis, Elasticsearch, Apache Flink, Apache Spark, Apache Kafka, Microservices, API Gateways, Kubernetes, and Docker, to name a few. In my current capacity as a Technology Leader at Ola Electric, my team and I focus on building highly scalable and robust Microservices and Data Pipelines for Ola Cabs and Ola Electric. We operate at an impressive scale of approximately 6 billion events per day, ensuring subsecond latencies. My responsibilities encompass making critical Architectural and Design decisions, overseeing High-Level Design (HLD) and Low-Level Design (LLD), conducting thorough code reviews, establishing and upholding technical standards within the team, spearheading Proof of Concepts (PoCs), fostering the development of highly efficient tech teams, and, naturally, engaging in hands-on coding.
