01SELECTED WORK
NOWCURRENTLY BUILDING
A few projects I’ve shared publicly, take them, fork them, build on them.
All core software, systems and infrastructure across these projects were developed in-house and are not available for third-party licensing or resale.
02EXPERIENCE
Three years, one throughline: designing systems people show up for, and building what they run on.
Official Lead Game Designer of the KEK ecosystem: College seasons, KEKV, King's Tomb and HAYLORD. Economy design, seasonal live-ops, creator programs and full-capacity launches.
→ 16,000+ registered players · every launch at full capacity · 98+ partnered streamers
Where it started: KEK Community's original 2022 test server. Gameplay systems, economy scripts and the server infrastructure that grew into the KEKV platform.
→ one test server grew into KEKV: 8,300+ members, running at its cap
Independent product development alongside the studio: heyCRM for insurance agencies, original web games, JARVIS AI and the platforms they run on.
→ heyCRM in daily agency use · RECON audience-AI for brands · original web games · JARVIS AI
The proprietary systems and engines running underneath everything above.
03CAPABILITIES
Not a wishlist, every skill below is proven in production, across KEK Studio’s worlds and my own products.
04SERVICES
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.
High-performance websites, dashboards and web applications with custom APIs, authentication, databases, admin tools and production-ready deployment.
Economies, progression, factions, jobs, launchers and full roleplay server architecture, designed as durable systems rather than isolated scripts.
Web3 products and game launches with mint flows, token logic, on-chain progression, marketplace thinking and community-ready launch infrastructure.
Custom internal tools, desktop apps and CRMs that match real workflows: imports, reporting, permissions, backups, launchers and update delivery.
Three.js, WebGL, motion and immersive interfaces for brands, products and portfolios that need to feel engineered, not templated.
AI-assisted tools, scoring systems, analysis pipelines and automation layers that turn messy inputs into usable decisions and repeatable workflows.
Yes. I work with clients anywhere, fully remote, in English or Turkish.
Websites and web apps, game systems and FiveM servers, Web3 launches, desktop software and CRMs, and interactive 3D web.

It depends on scope. Share your budget range and goals in the brief and I will tell you honestly what is realistic.
You do. Delivered client work is yours; my own products such as heyCRM and RECON can be licensed separately.
05ABOUT
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.
