Active systems on the bench

Open source on GitHub

A few projects I’ve shared publicly, take them, fork them, build on them.

Proprietary technology

All core software, systems and infrastructure across these projects were developed in-house and are not available for third-party licensing or resale.

From one test server
to an ecosystem

Three years, one throughline: designing systems people show up for, and building what they run on.

From idea to operating product

Strategy, interface, engineering and launch in one accountable pipeline. The scope can be a focused website, a full software platform, a game system or a custom product built around your business.

Web Platforms & Full-Stack Products

High-performance websites, dashboards and web applications with custom APIs, authentication, databases, admin tools and production-ready deployment.

Game Systems, FiveM & Live Worlds

Economies, progression, factions, jobs, launchers and full roleplay server architecture, designed as durable systems rather than isolated scripts.

Web3, On-chain Economies & Launches

Web3 products and game launches with mint flows, token logic, on-chain progression, marketplace thinking and community-ready launch infrastructure.

Business Software, CRM & Operations Tools

Custom internal tools, desktop apps and CRMs that match real workflows: imports, reporting, permissions, backups, launchers and update delivery.

Interactive, 3D & Premium Web Experiences

Three.js, WebGL, motion and immersive interfaces for brands, products and portfolios that need to feel engineered, not templated.

AI Tools, Automation & Data Intelligence

AI-assisted tools, scoring systems, analysis pipelines and automation layers that turn messy inputs into usable decisions and repeatable workflows.

Frequently asked questions

Do you work remotely and worldwide?

Yes. I work with clients anywhere, fully remote, in English or Turkish.

What kinds of projects do you take on?

Websites and web apps, game systems and FiveM servers, Web3 launches, desktop software and CRMs, and interactive 3D web.

How do we get started?

Send a short brief through the form on this page. It opens a ready-to-send email in your own account, and I reply personally.

How much does a project cost?

It depends on scope. Share your budget range and goals in the brief and I will tell you honestly what is realistic.

Who owns the code?

You do. Delivered client work is yours; my own products such as heyCRM and RECON can be licensed separately.

Systems thinker.
World builder.

I'm Hakan Efe Yalçınkaya. Since 2022 I've been designing, building and operating live gaming ecosystems, Web2 communities that hit full server capacity within days, and Web3 titles with real on-chain economies.

Everything my projects run on is built in-house: CRM platforms, game launchers, FiveM script suites, original web games and the server infrastructure underneath. I own the whole pipeline, concept, design, code, launch and live ops.

Work with me
  • End-to-end: design → code → launch → live ops
  • Studio work and independent products, one pipeline
  • Working languages: Turkish (native) & English
