I build the interface — and the systems behind it.

I'm Yusuf, a developer based in Istanbul, Türkiye, focused on AI tooling, full-stack applications and desktop software. I turn practical problems into connected products: the interface people use, the API behind it, and the automation that keeps it moving.

My background in automation, e-commerce and technical service shapes how I build: understand the workflow, make it easier to use, and pay attention to the details that matter after launch.

Interested in: AI application development · full-stack engineering · desktop products.

Selected work

Four projects, with a different engineering problem behind each one.

Riftroam — desktop software and release engineering

01 / Riftroam

A desktop companion for League of Legends.

Connects the client experience with customization workflows and in-app updates. My work spans the desktop interface, Rust integration and release delivery.

Tauri Svelte Rust

DerdiniSeveyim — mobile, web and real-time messaging

02 / DerdiniSeveyim

A social support and matching application.

A TypeScript monorepo bringing together an Expo mobile app, Next.js website and admin panel, and a NestJS API with authentication and real-time messaging.

React Native Next.js NestJS PostgreSQL

Windows FPS Utility — desktop settings automation

03 / Windows FPS Utility

System settings, with less manual work.

A portable WPF application that brings Windows power, visual-effect and gaming settings into one interface, with documented steps for reverting changes.

C# .NET WPF

Harborlights — reservations and administration

04 / Harborlights

From a static template to a working backend.

An educational hospitality project: I extended an existing HTML template into an ASP.NET Core MVC application with reservations, content management and an admin panel.

C# ASP.NET Core Entity Framework

Also exploring: AI developer tooling

YuefIDE is my AI development-environment project, focused on prompt building and code assistance. Its public repository currently contains the project overview.

What I work with

Area	Technologies I use
Interfaces	TypeScript, React, Next.js, Svelte, Tailwind CSS
Mobile & desktop	React Native / Expo, Tauri, Rust, C# / WPF
APIs & data	Node.js, NestJS, ASP.NET Core, PostgreSQL, Prisma, Redis
AI & delivery	Python, OpenAI API, LangChain, Docker, GitHub Actions

I care about clear interfaces, maintainable architecture and performance. I like working across product boundaries: connecting a mobile screen to its API, a desktop action to its native integration, or a release to its update flow.

GitHub, in context

_{Generated from public GitHub data; the collection date is shown in the chart. Contributions reflect the publicly visible calendar and the current month is partial. Language shares measure code bytes across owned public repositories, excluding forks — not proficiency or time spent.}

Data sources and scope

The activity chart uses the public GitHub calendar. It may include anonymized private contribution counts if profile settings expose them. The language chart uses the GitHub repository languages API; libraries or generated files counted by GitHub can affect the result. Private application source is not represented in that chart.
