Luke Larsen – Full-Stack Developer & Systems Architect

What I Do

Full-Stack Web Apps

From a fast marketing site to a full application with auth, data and an admin backend. PHP and JavaScript front to back, built to be maintainable long after launch — not just demoed once.

Systems & Performance

When it has to be fast or correct at the metal: Rust, C and C++ for native tooling, performance-critical services, parsers, and the WebAssembly that runs in the browser.

Infrastructure & DevOps

The Linux, Docker, Terraform and Ansible underneath. CI/CD, reverse proxies, self-hosting and deployment — I run my own homelab, and I'll run yours too.

Security Review & Hardening

Threat-modelling, code and config review, and hardening before things ship: TLS and headers, auth and input handling, secrets, and the boring correctness that keeps you out of trouble.

Need something that spans a few of these? That's the point — it's all one set of hands. Start a conversation

About

I'm a full-stack developer and systems architect with a background in web development, systems programming, and DevOps. I work in PHP and JavaScript on the front end, drop down to C, C++, and Rust when performance matters, and design and manage the Linux infrastructure it all runs on.

I contribute to open source projects, develop interactive applications and tooling, and manage my own self-hosted infrastructure. I bring that same end-to-end ownership to client work: architecture, implementation, deployment, and the maintenance afterward.

AI can generate snippets; shipping reliable software still takes someone who owns the whole picture. I bring the architecture decisions, security review, and accountability that turn code into production systems.

Currently Partnering with clients across a range of industries to deliver full-stack web and desktop applications, custom software and tooling, and scalable infrastructure solutions

Reyes leaned in the doorway, arms folded tight against her chest. "You're three hours late, Marlowe."

He shrugged off his coat, draped it over the chair. "Traffic."
