About Jatin

I am a data engineer and software engineer with a strong focus on building reliable data systems in distributed and production environments. I work across the full data lifecycle, from data ingestion and transformation to modeling, deployment, and monitoring.

My experience includes designing scalable data pipelines, working with cloud and containerized infrastructures, and collaborating closely with data scientists and product teams to turn complex data into actionable systems. I am comfortable operating in high volume, low latency environments and enjoy solving problems related to data quality, performance, and system reliability.

I have a solid background in Python and experience with distributed technologies such as Kafka, Spark, Kubernetes, and cloud platforms. On the data science side, I work with statistical analysis and machine learning when it brings real value, always with a focus on production readiness rather than experimentation only.

I value clean architecture, well tested code, and clear communication. I am used to working autonomously while staying aligned with stakeholders, and I enjoy taking ownership of systems that need to work reliably at scale.

    • ● Improved the reliability of the Datadog Agent on Kubernetes by fixing Admission Controller issues, including configurable UDS socket paths, safer handling of missing parent resources, and resolving leader-election race conditions to ensure consistent pod behavior.
    • ● Led performance and scalability improvements in Kubernetes metadata discovery by redesigning the resource cache, reducing API server load, migrating label-as-tags to ConfigMaps to lower etcd pressure, and cleaning up legacy Tagger abstractions.
    • ● Built practical debugging and validation tools for developers by adding workloadfilter and verify-cel CLI commands, making it easier to inspect active CEL filters, validate rules locally, and troubleshoot Unified Workload Filtering behavior.
    • ● Improved code quality and test coverage across multiple Datadog Agent components by writing reusable test utilities, adding unit and end-to-end tests for Kubernetes workloads, introducing typed workload metadata sources, and contributing to documentation and PR reviews.
