Andrew Walker

Architected and delivered scalable web applications using React, Node.js, and Rust; implemented modular design principles and maintained full-stack architecture. Designed and developed backend services with Python and Node.js; integrated third-party APIs and built secure, high-performance RESTful APIs.

Worked with clinical geneticists to create bioinformatics pipelines in AWS for analyzing cardiovascular disease risk and drug response (PGx). Used industry-standard tools such as samtools and bcftools to debug issues and support clinical laboratory operations including variant and gene curation and the diagnosis of rare and undiagnosed genetic diseases. Developed a visualization platform for lab bioinformatics data using TypeScript and Rust, enabling novel visualization of whole-genome data. Built a full stack application for tracking, managing, and analyzing genomic data using TypeScript, Next.js, and PostgreSQL.

Developed distributed Python/C++ applications to match genomic data to a database of over 1 million samples. Built scalable backend pipelines with PostgreSQL and Python for managing large volumes of genetic data. Integrated Nomad for multi-host deployment and collaborated with R&D to move bioinformatics machine-learning projects from experimental prototype to production pipelines. Led deployment across multiple hosts and data centers using AWS, GCP, Docker, Terraform, Kubernetes, GitHub CI/CD, and CloudFormation; worked with diverse data stores including MySQL, MongoDB, PostgreSQL, SQLite, Firebase, and DynamoDB.
