What I'm looking for

I seek senior backend or platform roles building AI/ML production systems, with strong collaboration, cloud-native tooling, growth opportunities, and measurable product impact.

I am a Senior Backend Engineer with 10+ years building AI-driven platforms, scalable APIs, and high-performance data pipelines for enterprise applications.

I design and optimize distributed systems and model-serving architectures, integrating MLflow, TensorFlow Serving, and SageMaker to enable reliable model deployment and low-latency inference.

My work has delivered measurable impact: 50K+ daily inferences at <150ms latency, 35% throughput improvement with distributed inference, and 40% faster release cycles through Terraform and CI/CD automation.

I collaborate closely with data scientists and cross-functional teams to productionize models, implement streaming feedback loops with Kafka, and deploy cloud-native solutions using AWS, Docker, and Kubernetes.
