Alyssa Carter-Ngo

Distributed Systems, Infrastructure, and Full-Stack Engineer

Software engineer with a deep understanding of how systems scale, break, and recover in environments where reliability and developer velocity are non-negotiable.

About Me

I'm a Software Engineer with deep expertise in distributed systems and cloud infrastructure. Currently at Amazon Web Services, I build and operate core networking services that power VPC and other critical AWS infrastructure. My experience spans from hyperscale data-plane services to secure key infrastructure and CI/CD pipelines that safely ship changes across classified and production partitions.

I thrive on solving complex technical challenges in high-reliability environments, whether that's optimizing VPC networking architecture for AI workloads, architecting key-management services for encryption, or introducing AI-assisted tooling to reduce operational toil.

As cofounder/CTO of a startup during university, I regularly subcontracted development work, learning to delegate effectively while maintaining accountability for results. I've been applying these skills increasingly in today's AI-powered development environment to accelerate delivery timelines.

Software Engineer

Building and operating core networking services that power AWS VPC and other critical infrastructure. Working on distribution-plane services, CI/CD pipelines, and key-management systems across multiple classified partitions.

  • Developed and maintained a distribution-plane service that constructs and distributes guest-network configurations powering VPC
  • Built a new CI/CD pipeline that dramatically improved reliability and speed of infrastructure changes
  • Optimized VPC networking architecture to accommodate new AI workloads
  • Architected key-management services for on-the-wire encryption across all encryption-capable instance types
  • Operated services in multiple high-side classified partitions for government partners worldwide
  • Wrote a custom MCP server and indexed 30,000+ documents, enabling AI agents to assist operations

Software Engineer (Intern)

Worked on the team for the BigMac service, a hyperscale data-plane service that powers NAT Gateway, NLB, AWS service endpoints, and many other AWS services. Focused on integration testing and network topology validation.

  • Developed a CDK-based integration-testing framework for non-standard network topologies
  • Architected custom CloudFormation resources with Lambda handlers to manage AWS-internal components that lacked native CloudFormation support
  • Integrated internal AWS tooling and imperative management methods to bridge gaps between declarative infrastructure-as-code and internal service APIs

Co-Founder & Chief Technical Officer

Co-founded a web development startup where I led the technical vision and execution. I worked closely with clients to transform their ideas into full-fledged web applications, managing the entire product lifecycle from initial design to final deployment.

  • Owned the end-to-end development of custom web solutions, working directly with clients and designers to meet business requirements.
  • Implemented agile development processes, leading iterative design, development, and review cycles to ensure high-quality deliverables and client satisfaction.
  • Managed subcontracted developers, overseeing project timelines to ensure successful delivery.
