What I'm looking for

I’m looking to build production-grade data and ML pipelines with strong MLOps: end-to-end orchestration (Airflow), repeatable dataset/model versioning, automated CI/CD deployments, and first-class observability—so data scientists can run workflows self-serve without hand-offs.

I’m a Senior Software Engineer with 12+ years of experience specializing in data engineering, pipeline orchestration, and ML platform infrastructure. I built the data foundation for an ML organization from the ground up—ingesting from an S3-based data lake, transforming and versioning datasets, and engineering production-grade features orchestrated end-to-end with Apache Airflow.

I’m hands-on across the full ML lifecycle: I designed Airflow DAGs for ingest, cleaning, and transformation to produce ML-ready datasets; built feature engineering pipelines feeding SageMaker training jobs; and implemented data versioning to keep data and model versions consistent. I also created a custom lightweight model registry on S3 as a deployment gate, coordinated model and data versions between Airflow (training) and CircleCI (deployment), and enforced controlled rollbacks—while defining observability standards from scratch using structured logging and New Relic metrics to give teams full visibility into pipeline behavior and model health.
