Utility
Independent developer / homelab hobbyist / Istanbul
I’m Halil Oğuzcan Toptaş. I build web interfaces, homelab systems, and browser experiments.
I work with Next.js, TypeScript, automation, homelab operations, and browser runtimes. I document the decisions, constraints, and failure modes behind each build.
Three kinds of work
I build client-facing interfaces, self-hosted systems, and browser experiments. Each project states its scope, constraints, and shipped result.
Product interfaces
Landing pages and frontend systems that explain a product, show evidence, and guide visitors to the next action.
Homelab + automation
Small, inspectable systems for learning self-hosting, operations, repeatable workflows, and the failure paths between them.
Browser experiments
Motion, WebAssembly, game runtimes, and interface studies isolated from the main product payload.
Featured projects from the archive
The archive lists every project. Selected entries explain the problem, implementation, stack, and outcome in more detail.
Motion supports orientation
Scroll-linked movement shows relationships between sections, and state changes confirm user actions. Reduced-motion users keep the same content and navigation.

A live demo adapted from home-media-portal: DOSBox-X for Web, a curated ROM manifest, and a lazy iframe that keeps the runtime off the homepage until requested.
How I take a build from idea to release
The process is built around visible decisions, tight scopes, and proof before release.
Frame
Define audience, conversion path, constraints, and what should not be built.
Shape
Turn the brief into routes, content models, tokens, components, and motion boundaries.
Ship
Commit in slices, verify with CI, review in browser, and release with notes.
Have a website or interface to build?
Send the product, portfolio, or landing-page problem. I can help turn it into a buildable scope.
