What I'm looking for

I’m looking for a senior role where I can build reliable cloud data platforms—real-time streaming, modeling, and AI/ML—partnering with product and operations to deliver measurable business impact.

I’m a Senior data engineer who thrives on turning business requirements into scalable, production-grade data engineering and AI/ML solutions. At CEMEX TOPMIX LLC, I collaborated with sales, operations, customer care, stakeholders, and the CEO to design “Big Data Engineering” solutions that improved how resources, inventory, and customer journeys run day to day.

I build end-to-end systems across batch and streaming: Customer 360 and hyper-personalized campaigns (improving retention by ~20%), near real-time inventory and supply chain optimization (reducing out-of-stock incidents by 30%), and forecasting delay risks using Databricks, Airflow, and critical-path dependencies (reducing unexpected delays by 18%). I also containerize and automate pipelines with Docker, Kubernetes, DevOps, CI/CD, and Terraform, and I’ve delivered strong outcomes like reducing idle machinery time by 30%, fraud analytics that cut fraudulent chargebacks by ~25%, and migration performance improvements (44%).
