Created Spoonfy, an AI-powered language-learning app to build truly native fluency in a foreign language via a unique verbal-only approach.Developed open-source Python tooling to automate dataset creation, perform training and inference. Uses HuggingFace and PyTorch.Developed Spoonfy Editor, a purpose-built multiplatform iOS/macOS app for human volunteers to create & clean datasets in a compelling and intuitive manner. Written in Swift/UIKit/SwiftUI.

Worked on a project from early concepts through two HW release cycles.Designed & built the OTA (Over-the-Air) service, a fault-tolerant multi-tenant microservice-based system with embedded software to safely & reliably keep fleets of edge caches up to date under challenging network/electrical conditions. Hosted on AWS using AWS Lambda, DynamoDB, S3, SNS/SQS, AWS IoT Jobs, IAM, etc.Created the HSS (Hot-Swap System), an automated system that maintained undeployed edge caches, drastically reducing backhaul costs.Incorporated structured logging & tracing into our cloud services, reducing ticket resolution times.Built pipelines/automation for CI/CD on Amazon’s internal platform in Ruby.Wrote automated unit/integration testing for cloud/embedded packages.Designed REST APIs and built monolith (Docker, AWS Fargate) services.Built embedded software (daemons) in C and Go for OpenWRT that performed IPC using Ubus. Wrote networking rules using iptables.Built libraries in Go, Python for various embedded/cloud use cases.Mentored new team members, wrote documentation/runbooks, participated in Agile development, ran tech talks, participated in on-call rotations.

Created Phoenix, a videogame emulator & library manager built with a strong UX focus. Built for high real-time performance and low I/O latency. Multithreaded with a flexible pipeline architecture.Written in C++/QML/JavaScript using the Qt framework. Uses SQLite for library, metadata storage. Uses Objective C for macOS-specific code.

Ported a Linux kernel driver to Windows as part of a computer security research project at Penn State called "Process Firewall". Written in C.

Developed a tool called "Reaper" at Northrop's Information Management & Storage org for evaluating the performance of high-speed (40-100Gbps) network hardware. Written in C.
