What I'm looking for

I seek roles where I can lead delivery of scalable AI systems, implement MLOps best practices, mentor teams, and drive measurable business impact in collaborative, product-driven environments.

I am a Lead Data and Machine Learning Engineer with over 10 years of experience building and scaling end-to-end data and AI solutions across fintech, SaaS, and enterprise environments.

I specialize in designing robust ETL/ELT pipelines, cloud-native architectures on AWS, GCP, and Azure, and production-grade MLOps practices including CI/CD, model monitoring, and cost optimization.

I have delivered measurable outcomes such as improving data velocity by 45%, enhancing model accuracy by 30%, tripling data throughput, and saving $150K+ annually through standardization and automation.

I am passionate about Retrieval-Augmented Generation, LLM fine-tuning, multimodal AI copilots, and leading cross-functional teams to operationalize responsible, observable, and scalable AI systems.
