Work Experience & Projects

Working full-time on-site in Vietnam, developing scalable cloud-native backend microservices, automated CI/CD delivery pipelines, workflow engines, and production observability solutions using Golang and AWS.

Focus areas:

• Backend microservices and workflow engines with Golang and Amazon DynamoDB — single-table schema design optimized for sub-10ms transaction latency
• Multi-environment cloud infrastructure provisioned with AWS CloudFormation (Lambda, ECS, S3, IAM) across secure isolated environments
• CI/CD pipeline automation with Buildkite — integrated unit tests and end-to-end integration test suites for faster, more reliable deployments
• Production observability with Datadog APM tracing, custom metrics dashboards, and alerting rules for real-time system health monitoring
• Mission-critical payment gateway integrations (Westpac QuickStream, VisionNext) handling high-throughput asynchronous financial transaction streams

Key stack: Golang, Amazon DynamoDB, AWS Lambda, ECS, S3, IAM, CloudFormation, Buildkite, Datadog.

Contributed to end-to-end development of a full-stack web application in Vietnam — from frontend interfaces and backend APIs through containerization and AWS cloud deployment.

Focus areas:

• Responsive web interfaces with Next.js and TypeScript — component architecture, routing, and API integration
• High-throughput RESTful APIs with C# and .NET Core — clean layered architecture, database schema design, and third-party service integration
• Docker containerization for consistent local, staging, and production environments — optimized multi-stage build pipelines
• AWS cloud deployment, resource usage optimization, monitoring configuration, and performance support
• Database schema architecture and API gateway design discussions contributing to system-level decisions

Key stack: Next.js, TypeScript, C# (.NET Core), PostgreSQL, Docker, AWS.

Worked on-site in Vietnam within a structured cloud security program — hands-on practice with secure AWS infrastructure configuration, compliance auditing, and Infrastructure as Code.

Focus areas:

• AWS IAM least-privilege policies, VPC subnets, route tables, security groups, network ACLs, and S3 bucket security controls
• Encryption at rest and in transit, bucket policies, and foundational cloud security controls aligned with AWS Well-Architected Framework
• Infrastructure as Code with Terraform and AWS CloudFormation — writing, testing, and deploying compliant infrastructure scripts
• Cloud misconfiguration research and remediation using AWS monitoring and audit tooling (CloudTrail, Config)
• Professional workflow experience through direct mentorship with senior cloud engineers

Key stack: AWS IAM, VPC, S3, CloudTrail, Terraform, CloudFormation, Linux.
