<section id="about">
<p>I have 13+ years of experience working at all levels of the software stack, including front-end, back-end, microservices, testing, database, cloud, infrastructure as code, and CI/CD. I'm passionate about building reliable, type-safe, fault-tolerant, distributed systems without over-engineering. I often specialize in DevOps but approach it like a software engineer.</p>
<p>My background in DevOps and full stack development makes me a highly desirable candidate for Staff Engineer roles. My roles have primarily focused on DevOps, and I've always worked across teams and with all parts of the software stack, giving me a unique, holistic perspective. I love mentoring, training, and collaborating with cross-functional teams, users, customers, and business leaders. I'm motivated by improving team efficiency, polishing rough edges, and fixing issues that are often ignored.</p>
<p>My current favorite tools are Rust, Typescript, Deno, React, GraqhQL, Pulumi, Kubernetes, GitLab, Linux, and Git.</p>
