Architecture Expertise by Domain
My technical portfolio spans five core domains of modern software architecture. From cloud-native infrastructure to frontend visualization, each area represents deep hands-on experience building production systems at scale. These presentations distill years of architectural decisions, patterns, and lessons learned from real-world implementations.
Whether you're exploring serverless patterns on AWS, implementing OAuth flows with WSO2, or building ML pipelines, these resources provide practical guidance grounded in enterprise requirements and operational realities.
