Yoann AMAR ASSOULINE

Software Developer

With over 20 years of practice in computer science, including 15 years of professional experience in Software Development and Semiotics, I started learning programming and computer graphics as a self-taught developer at 14, back in 2004.

In 2021, I founded my company in order to develop alone and from scratch (without AI for content generation) my first game Goldanniyatech, and to share my expertise as a computer science instructor.

Computer Science Instructor

Independent Higher Education Instructor since 2022, I provide teaching services to multiple institutions for a wide range of audiences (Associate’s, Bachelor’s, Master’s, and adult career changers), primarily in programming, 3D graphics, 3D game development, and web development.

PhD in Semiotics

Specialized in Semiotics applied to 3D software development, I have been studying Semiotics since 2013, starting with a Bachelor’s (French Licence) and Master’s degree at Paris Cité University, before pursuing a Ph.D. research at Sorbonne University in 2018.

In 2024, I successfully defended and published my doctoral thesis, which provides a semiotics and technical analysis of the evolution of 3D game development since the 1990s.

Creating My 3D Game

I’m developing alone and from scratch my first Action-Adventure game Goldanniyatech, allowing me to maintain full creative control over my virtual world, with these tools:

Unreal Engine 5 for gameplay programming (Blueprints & C++) and world creation
Blender for modeling, sculpting, and animation
Substance Painter for creating PBR textures
FL Studio for composing lightweight sounds and music (not a specialist of FL, thought)

Besides, I don’t use generative AI to automate modeling or programming tasks. While I do use this fantastic tool for brainstorming, learning, and skill improvement, I firmly believe that hand-crafted models and code is the only way for me to maintain full control over my game’s quality (and creativity).

Developing My Website

Alongside my game, I am continuously developing my website using the Astro static site framework, HTML and CSS languages, and the TypeScript programming language (a superset of JavaScript).

Teaching Computer Science

Computer Science Instructor since 2022, my courses focus on hard skills and real-world projects based on technologies I’ve worked with extensively over the years.

Courses Taught

I offer courses on the following topics, preferably on-site:

3D Game Development from scratch with Unreal Engine 5 (UnrealEd, Blueprints, C++, assets importing, etc.)
Programming in C++ 20 and Python 3 with a focus on fundamentals (data types, programming paradigms, software architecture, etc.)
3D Computer Graphics involving the creation of 3D models in Blender for offline rendering (Eevee, Cycles) or real-time 3D rendering in Unreal Engine. PBR texture creation in Substance Painter
Web Development using the Astro framework, with HTML, CSS, and TypeScript
Fundamentals of computer science, including history, hardware, office tools (Microsoft 365), and more

Game Engine

I have deep expertise in Unreal Engine 5 as a solo developer, with a focus on gameplay systems, open-world environments, animation scripting, visual effects (Niagara), and NPC artificial intelligence (behavior-driven, not generative AI).

I write in Unreal C++ for low-level base classes with Blueprint-exposed properties and methods. I have strong knowledge of engine architecture and best practices (smart pointers, UBT, UHT/reflection, GC, UObject lifecycle, CDOs) and extensively use Unreal Gameplay Framework (GameInstance, GameState, PlayerState, SaveGame). I tend to follow Unreal’s opinionated architecture.

I use Blueprints for rapid prototyping (Construction Scripts, Timelines, delegates, interfaces) and to instantiate my custom C++ classes. I rely on C++ as Blueprints will be deprecated in a future UE 6.X release in favor of Verse.

As an open-world specialist, I use World Partition (HLODs, Data Layers), optimize meshes rendering & reduce draw calls (ISM, HISM, Packed Level Actors, custom C++ culling, master materials & instances), and use a modular workflow (Level Instances, Blueprints’ Construction Scripts).

I also work with materials (Master Materials with parameters, Material Instances), Enhanced Input, Animation Blueprints, Niagara systems with complex emitters, rudimentary Artificial Intelligence behaviors (Behavior Trees, Tasks)

3D Graphics

I have extensive expertise in Blender and Substance Painter as a 3D generalist, creating both hard‑surface and organic models of all kinds.

I create all my stylized assets entirely from scratch in Blender, starting from primitive geometric shapes (cube, sphere, torus, etc.). I never rely on 2D blueprint references or concept art; instead, I block out forms directly in the viewport.

My modeling approach is based on traditional polygonal modeling techniques using basic operations (edge loops, extrusions) and non-destructive modifiers (mirror, array, subsurface). I rarely use sculpting unless I need to reshape the overall structure of the mesh. I also do quick UV unwrapping while ensuring it’s optimized for the engine (no overlapping UV islands, optimized texel density)

For animation, I use keyframe animation to test basic models before exporting, and I handle rigging and skinning for my organic meshes for armature or bone-based animation (with custom rigs only). I tend to avoid Shape Keys for exporting my meshes in favor of reusable bone-based animations in Unreal.

I export all my models in the FBX format and solve issues when needed (normal orientation, scene scale for animated rigs, exporting deformation bones). I’m also knowledgeable in USD and glTF exporting to prepare for Unreal Engine 6.

For texturing, I work in Substance Painter with a semi‑stylized PBR art style. I bake directly from my low‑poly meshes (without HPM) and use generators, smart materials, and filters.

Web Development

I design and maintain my Goldanniyatech website entirely from scratch, using HTML, CSS, and the TypeScript programming language (superset of JavaScript). I’ve chosen to avoid using UI libraries or frameworks like Tailwind or Bootstrap to maintain full control over my site’s design.

Since my website is purely static, I chose the Astro framework, with an SSG build (Static Site Generation). This approach helps me achieve better performance, which I regularly measure using tools like Lighthouse (PageSpeed Insights), while also providing a modern, scalable architecture for my content.
