Gameplay Systems
Core loops, combat, movement, inventories, interaction — architected to scale without falling over in the third act.
Mohamed Nasr.
Scroll
A one-person studio,
disguised as a freelancer.
I'm Mohamed Nasr — a solo game developer from Cairo with a single, stubborn focus: building polished, playable experiences in Unreal Engine.
Over the past six years I've taken dozens of projects from empty level to shipped build. Gameplay systems, level design, Blueprints, C++, materials, VFX, tools, UI — the whole pipeline lives in one pair of hands. When something is wrong, I fix it. When something is missing, I build it.
Clients come to me when they need someone who can own a concept and deliver it without a committee. No handoffs, no meetings about meetings, no "that's not my department." Just a game that works, feels good, and ships on time.
If you're building something in Unreal and you want it done right — you're in the right place.
Full-stack Unreal Engine.
Every layer of the pipeline.
ii.
C++ (High-Level)
Deep Unreal C++: modules, subsystems, gameplay framework, custom components, and the boring-but-critical architecture work that holds a game together.
iii.
Blueprints
Clean, legible Blueprint graphs that don't turn into spaghetti. Macro libraries, interfaces, and patterns that non-programmers can actually read.
iv.
Networking
Replication, RPCs, authority, prediction, rollback-friendly design. Multiplayer that actually works over the wire — not just in the editor.
v.
AI
Behavior trees, EQS, state trees, perception, pathfinding. AI that feels reactive and alive — and debuggable when it misbehaves.
vi.
Niagara & VFX
Impacts, trails, weather, ability feedback — effects that make the game feel alive without tanking the frame budget.
vii.
Tools & UI
Editor utilities, Python tooling, UMG interfaces. The unglamorous infrastructure that turns a week of work into an afternoon.
viii.
Machine Learning (High-Level)
Integrating ML models into gameplay and tools — classification, inference, data pipelines. Practical ML that solves real problems, not research papers.

What clients say
after the build ships.
The graphics are insanely cool, the atmosphere is perfect, the little cinematic sequence at the beginning is so cool, the controls are really solid… and there’s both flying and ground enemies. The sound effects and background music give it the perfect vibe. I’m still extremely impressed with this project and how good it looks for such a small time period of development.

If there’s anything you need in Unreal Engine, this guy can do it. His knowledge of the program is vast and in-depth, and he quickly learns complex new tools and plugins. Match this with his high level of C++ skill and you have an all-in-one Unreal Engine solution for any need. Nasr is my go-to developer for everything, he is very polite, creative and honest. Couldn’t recommend more.

Working with Mohamed was absolutely amazing! He provided me with an amazing foundation and prototype to continue building my project off of. He kept amazing communication during the entire process and sent me amazing video and photo progression updates. If you’re starting a project and need to hire external help, definitely go with Mohamed.

Nasrrx helped me with the practical component for my MFA degree (Game design). A very complicated project that changed shape and direction multiple times over the course. Nasrrx was always very accommodating, helpful and eager to assist, input and grind as needed. The final product played great, worked smoothly and looked fantastic! Thanks for everything M!

Six years.
One craft.

2018–2019
General Dev · Google Play Console
Started as a general developer and published work on the Google Play Console — a shipped game and a shipped app live on the store. Early proof that I could take an idea from empty folder to a build someone else could install.

2020
Going Freelance
Launched freelance services and started taking client work. Fiverr, Upwork, direct contracts — smaller gigs to begin with, building a reputation one delivery at a time.
-
2021
Bigger Projects
Graduated to larger engagements — full Unreal Engine projects, bigger budgets, longer timelines. The work became less about one-off fixes and more about owning whole systems and slices.
-
2022–2023
Content & Community
Started the @nasrrtm YouTube channel — devlogs, tutorials, breakdowns. Teaching the craft I was using every day and growing an audience that still watches today.

2024–2025
UE5 · Full Pipeline
Moved heavier projects into UE5. Deeper C++, multiplayer networking, AI, tooling, and optimization work. Featured in a community spotlight as one of the solo devs worth watching in the region.
