What I'm looking for

I seek roles building scalable, AI-enabled backend systems with strong dev practices, cloud-native infrastructure, and opportunities to lead technical teams and improve delivery.

I am a Senior Backend Engineer with 7+ years designing high-performance backend systems, distributed microservices, and AI-driven applications across cloud platforms. I focus on Python-first architectures and practical AI/ML integration to deliver reliable production systems.

At Oracle, I led a team of six developers to deliver educational AI systems, introduced Server-Sent Events for real-time UI synchronization, and architected Kafka-based event pipelines to improve scalability and reduce downtime.

Previously I built AI-ready backend services and optimized Java and Python microservices to raise performance and client satisfaction, and earlier I developed cloud-native, high-throughput systems using async processing, Celery, and serverless components to lower costs and improve response times.

I prioritize high availability, observability, and automated CI/CD while mentoring teams and driving measurable improvements in delivery speed, reliability, and user engagement.
