Project Description:

I am looking to hire an experienced developer or team with strong expertise in cryptographic algorithms, web scraping, and app development to create a Crash Prediction App for the Aviator Game. The goal of the app is to predict the game’s crash multiplier before the round starts, using the "Provably Fair" system the game is based on.

How the Game Works (As per public documentation):

The Aviator game uses cryptographic fairness via the "Provably Fair" system.

Each round's result is generated using a SHA512 hash of a combination of:

A server seed (random 16-character string generated by the game operator)

Three client seeds (generated by the first three players joining the round)

The server seed is published in hashed form before the round, and the client seeds are generated during gameplay.

Your Responsibilities:

Analyze and Reverse-Engineer the Game Logic:

Understand how the server and client seeds are structured and published.

Capture and interpret the hashed values using SHA512 hashing.

Web Data Extraction (Scraping or Monitoring):

Build a tool to monitor and extract server and client seed data in real-time from the Aviator game webpage
If data is encrypted or obfuscated, implement decryption or browser-level interception.

Prediction Engine:

Implement the hash merge logic (server seed + client seeds).

Generate the SHA512 hash.

Decode the game crash multiplier from the hash before the round starts.

User Interface (Mobile or Web App):

Build a simple app or dashboard that:

Shows the upcoming round’s predicted result.

Displays the server and client seeds used.

Optionally logs historical predictions vs actual results.

Hi! I’m currently looking for an anime-style illustrator to help me with the covers of my new digital novel.
I've already created the base designs for the covers myself (I’m not a professional artist, but I’ve done my best). What I’m looking for now is someone who can take them to the next level in terms of quality and polish.

This is a dark fantasy novel with anime vibes, and I’d love to reflect that atmosphere in the artwork. The character designs are already done, and in some cases, the covers are nearly complete — they just need refinement and a professional touch to improve the illustration and composition.

Later on, I’d also like to commission scene illustrations and world-building visuals, so this could be a long-term collaboration.

I saw your work and I really liked it!
If you're interested, let me know so I can send you the first drafts.
I'm also open to hearing about your pricing and rates.

Hello! I need someone to design a logo for a website (and kinda a banner logo+name or name+logo or both in one)

I think something similar or like that cube (but probably better) would be nice as a logo: https://imgur.com/gzG9w5B (without the "live" inside). Maybe "news" or the name of the site "Cryptogen" could be written on it, I don't know. Just like I am up to anything else aside that cube if you have better ideas.

In the end I need:

- a favicon with just the logo
- a banner really light/optimized for my header on each page
- the logo vectorized with transparence on a sheet on Canva (so I can put on each cover image of my website).

Feel free to give me some examples/ideas or ask any question. Thank you!
