I am a Senior Java Software Engineer with 15 years of experience designing, developing, and maintaining cloud-native applications, distributed systems, and microservices architectures.

I specialize in Java, Spring Boot, RESTful API design, event-driven systems, and scalable data ingestion and retrieval platforms. I focus on delivering reliable, high-performance software through thoughtful architecture, schema design, and query optimization.

My background includes work across AI networking, blockchain and digital assets, payment platforms, e-commerce, and data-center networking. I have built solutions that improve operational efficiency, latency, reliability, and developer productivity.

I am experienced with cloud infrastructure and DevOps practices, including AWS, Azure, Google Cloud, Kubernetes, Docker, and CI/CD automation. I also work with relational and NoSQL data stores such as PostgreSQL, DynamoDB, and Elasticsearch.

I enjoy leading technical initiatives, contributing to architectural decisions, and collaborating with cross-functional teams to solve complex engineering problems. I am committed to security, data privacy, compliance, and software quality.

I also mentor engineers in coding standards and development best practices, helping teams build a culture of continuous learning, strong engineering execution, and sustainable delivery.
