What I'm looking for

I seek backend or platform roles where I can lead scalable, AI-integrated systems, improve security and performance, and drive measurable business impact in cloud-native environments.

I am a senior backend engineer with 10 years of experience designing and scaling enterprise-grade platforms that integrate AI to drive measurable business value. I specialize in Python/Django, Java/Spring Boot, and Node.js, building high-performance, secure, and resilient systems across fintech, hospitality, and travel domains.

I have led backend development for payment processing, fraud detection, and AI-powered compliance workflows, directing teams and systems to shorten feature delivery and improve transaction security. I designed and deployed TensorFlow fraud detection models that reduced fraudulent activity and lowered manual review time, and I optimized PostgreSQL and Redis to boost throughput and reduce latency.

I modernize architectures using microservices, event-driven patterns, and cloud-native tools (AWS, Docker, Kubernetes, Terraform). I deliver robust APIs (REST, GraphQL, gRPC, Kafka) and automated CI/CD pipelines that improve uptime, performance, and developer productivity while driving growth through personalization and integrations.
