Development of backend logic in Node.js with deterministic result

Hello!

First, I want to assure you this is not an AI-generated comment.

I am Ahmed Atwa, a software engineer with major experience in TypeScript and Node.js. I have made many Node.js backends, systems and platforms before, including a Managed Cloud Hosting platform, a Recruitment System, and most importantly, I have made many game mods for a game called Warcraft III using TypeScript. You can check everything out on: https://www.github.com/nightknighto

I studied and have solid knowledge and understanding of cryptography, so I fully understand the stated requirements. I am well-suited and prepared to take on this new challenge.

And as a token of appreciation for you being my first customer, I will provide you with a free gift. You can choose from the following:
… - Complete Docker configuration for the project.
- Complete Kubernetes configuration for the project.
- Simple CI/CD to automatically deploy any new updates.
- Simple frontend to test out the backend functionalities.

Interested? Kindly send me the specification and let us discuss!

Hello.

We are The Dev Company team, specializing in backend development on Node.js and TypeScript, as well as having experience in cryptography, game mechanics, and verifiable logic.

What we can do:

– Implement deterministic mechanics based on seed-based RNG, hashes, salts, and other cryptographic tools;
– Thought-out mechanism for generating and verifying results (before and after the action);
– Flexible architecture to allow scaling and refining mechanics;
… – If necessary — model basic physical interactions of objects;
– Work carefully, quickly, and with understanding of how similar logic works for competitors.

Ready to discuss details and receive the technical assignment privately.

Waiting for your response.

Hello!

I am ready to undertake the implementation of backend logic in Node.js using TypeScript.
I understand the key requirements:

– Deterministic calculation of the result before the action begins (seed-based RNG, hashing, salt)
– Ability for post-factum verification of outcomes
– Use of cryptographic primitives
– Flexible architecture with the possibility of refinement
… – If necessary — implementation of basic object physics

I have experience in creating similar mechanics — I have implemented verifiable game mechanics with predictable results on the server side, worked with Crypto, seedrandom, OpenSSL, and other tools. I also have cases in my portfolio.

I am ready to discuss the technical specifications, review competitors, and propose an architecture.

Hello Ihor,
Your idea of a gamified mobile product sounds very interesting. We specialize in creating B2C platforms with gaming mechanics that combine user experience, technology, and business goals.

We create:
- Gamified mobile applications
- Unity/AR games with backend on ASP.NET Core
- Integration with eCommerce / CRM / API
- Analytics, rating systems, rewards
- Mechanics with character development and progression
…
To get started, it would be helpful to clarify:
- What is the target audience of the game?
- What is the core gameplay (mechanics)?
- Is there a plan to integrate with eCommerce or a real product?
- Which platform do you focus on: iOS, Android, or both?

We have experience in similar projects. Here are a few examples:
Captain TCG — a mobile AR game with ship development, token scanning, and interaction with physical products:
- 100k+ downloads
- 20k+ concurrent players
- Integration with retail chains, ROI analytics

Golden Wood — a mobile game + eco-platform:
- Player buys a tree in the game — planted in the real world
- Full tokenization, backend development
- Website on Next.js/Nest.js + mobile Unity app
https://freelancehunt.com/showcase/work/golden-wood/1961710.html

I would be happy to discuss the details of your project, timelines, budget, and next steps in private messages.
