What I'm looking for

I seek a senior engineering role building scalable, AI-enabled backend and data platforms in a collaborative, product-driven team with strong engineering practices and growth opportunities.

I am a Staff Software Engineer with 11+ years building large-scale distributed systems, AI-driven platforms, and real-time data pipelines across cloud-native environments. I have led high-impact engineering initiatives at Instacart and Amazon, delivering scalable microservices, ML infrastructure, and data lake architectures that support millions of users and mission-critical workloads.

My core expertise is backend development in Go and Python, cloud infrastructure (GCP/AWS), streaming systems like Kafka and Flink, and AI/ML integration using PyTorch and TensorFlow. I drive reliable production systems with CI/CD, container orchestration, observability, and security best practices while mentoring engineers and collaborating cross-functionally to accelerate delivery.
