Henry Kiem

Zeptta · Seattle, WA

• Lead engineer on an AWS Resilience Hub implementation covering 50+ production services across four product verticals. Derived service definitions, user journeys, and recovery objectives (RTO/RPO) from infrastructure tagging and EKS namespace structure, working with service owners and domain leads in three countries to settle what belonged to each service while the platform was mid-migration.
• The deployment is central to the client's compliance with GLI-33, the regulatory standard for licensed event wagering systems, where disaster recovery and business continuity are audited controls.
• Trained the client's staff resilience and security analyst, new to both Resilience Hub and Terraform, to own and extend the deployment in-house.
• Escalated bugs blocking infrastructure-as-code deployment and cross-account administration to the AWS service team, and worked with them until fixes shipped during the engagement.
• Extending the deployment into additional domains and integrating AWS Fault Injection Service, running game days against the same service definitions to exercise incident response, with experiments codified in Terraform.

AWS for Games · Seattle, WA

• Led development of the Cloud Game Development Toolkit (105 stars, 46 forks), an open-source infrastructure-as-code repository for deploying Unreal Engine Horde, Cloud DDC, and Perforce on AWS. Set its architecture, contribution standards, CI/CD pipelines, and documentation. The contribution model brought outside engineers up to core-team scale, including 24 merged pull requests from a single external studio.
• As the solutions architect aligned to Perforce, led alignment on cloud strategy with their executive team. Built the original proof of concept for an MCP server connecting AI coding agents to Perforce P4 version control and delivered it to Perforce, who productized it as their official p4mcp-server, now community-maintained at roughly 2,200 monthly downloads.
• Led the Cloud Game Development focus area. Worked with studios including EA, Warner Brothers, and Riot Games as a specialist alongside their account teams, advising on build infrastructure, cost management, and DevOps architecture.
• Presented cloud infrastructure patterns to 100+ attendees at UnrealFest 2024 and delivered chalk talks at AWS re:Invent 2024 (GAM304) and 2025 (IND354).

Amazon Luna · Seattle, WA

• Built GDPR compliance integration services for the Luna commerce platform.

Amazon Luna · Seattle, WA

• Designed and shipped React/TypeScript administrative portals used daily by 20+ engineers to manage in-game purchases, entitlements, game-session authorizations, and customer permissions; still in use after the internship ended.
• Built an automated regression testing service on AWS Step Functions parallelizing behavioral tests across commerce microservices.

Moovila · Charleston, SC

• Built frontend features in AngularJS for an enterprise project management platform, including its mobile experience.
• Ran market analysis of telematics vendors for corporate construction partners.

Neural Acoustic Processing Lab, Zuckerman Institute, Columbia University · New York, NY

• Administered EEG recording sessions with human subjects under an approved IRB protocol and completed Columbia's human-subjects research training. Built analysis pipelines mapping neural responses to time-aligned acoustic and semantic representations of natural-speech stimuli in Python (word2vec) and MATLAB, for research on how listeners encode linguistic structure.

BS Computer Engineering, minor in Philosophy · New York, NY

• Dean's List, School of Engineering and Applied Sciences.
