90 USD Mod for Minecraft Forge 1.20.1 on Inventory, horse harness for the server
Javascript and Typescript
I implemented a custom mod for a Minecraft server aimed at expanding the standard inventory system and creating a deeper gameplay mechanic for item storage. The main idea of the project was to rethink the player's basic inventory: instead of standard access to all slots, a bag system was introduced that opens additional space depending on the type and size of the equipment. This made the gameplay more logical, atmospheric, and closer to the medieval style of the server.
Within the mod, several types of bags for the character were implemented, which are equipped in a separate slot and expand the available inventory. Each bag has its own capacity level, allowing the player to gradually gain more options for carrying resources. If a bag is not equipped, some slots remain inaccessible, creating an additional element of balance and affecting resource management during survival, trading, or traveling.
… A separate horse inventory system was developed with support for saddle bags. The player can equip the horse with special bags of various sizes that open additional slots for transporting items. For this, a separate interaction interface with the horse was created, displaying the slots for equipment, saddles, armor, and bags. The interaction logic between items was configured so that the mechanics work correctly and do not conflict with the basic rules of the game.
From a technical standpoint, the project included a complete implementation of the modification on Minecraft Forge: registration of new items, menus, interfaces, and tabs, creation of custom GUIs for the player and horse, configuration of client-server interaction through network packets, as well as the implementation of an inventory data saving system. Custom slot handlers, dynamic inventory containers, and patches for the game's base classes were used to integrate the new mechanics into the standard Minecraft architecture.
Special attention was paid to the visual design. The inventory interface received a stylized design in a medieval paper style, enhancing the server's atmosphere and improving the overall experience of using the mod. Localization of item names, hints, system messages, and interface elements was also performed, making the mod understandable and convenient for players.
As a result, not just a set of new items was created, but a full-fledged server mechanic that changes the approach to working with the inventory, adds new opportunities for transporting resources, and organically integrates into the overall concept of the gaming server. Such a mod can be used in RPG, medieval, survival, and roleplay projects where atmosphere, progression, and unique gaming systems are important.

135 USD Mod for Minecraft Forge 1.20.1 on Block-Mine for server
Javascript and Typescript
A mod for the Minecraft server on Forge 1.20.1 that adds a special block-mine for automated resource extraction. The player can choose the desired resource and set the working radius of the block, after which the system analyzes the number of corresponding blocks within the area and based on this generates passive resource income over time.
The mod is implemented with consideration for server performance, stable operation, and flexibility of configuration for a specific project. Such functionality is well-suited for RPG, economic, and survival servers, where it is important to add automation, base development, and additional earning mechanics for players.

1000 USD Telegram Mini App Star Wars
Bot Development
Test all the functionality of the Telegram Mini App Bot using the tag — @StarWarsArenaBot
I developed a Telegram Mini App themed around Star Wars with full gaming logic, a web interface, a Telegram bot, and an administrative panel. The project is an interactive browser game within Telegram, where the user launches the application through the bot, creates a character, chooses a side of the Force, and interacts with game mechanics in real-time.
… The system includes a client part, server API logic, a Telegram bot for players, a separate admin bot, and a web admin panel for managing the game. The main goal is to create a full-fledged gaming product with a well-thought-out architecture, custom design, and the ability for stable deployment on a server.
Implemented in the project:
• Telegram bot to launch the Mini App
• Separate admin bot
• Web application (Telegram WebApp)
• Registration and character creation
• Faction selection (Jedi / Sith)
• Leveling and stats system
• Ability restrictions by factions
• PvP arena with queue and combat logic
• Planet capture with rewards
• Daily modes (boss, farming)
• Inventory and equipment
• Item transfer and deletion
• Shop (in-game currency + donations)
• Crafting and weapon upgrades
• Online player status
• Rating and leaderboard
• Maintenance mode
• Secure authorization (Telegram init data)
Players can develop their characters, participate in PvP battles, collect equipment, farm resources, upgrade abilities, and engage in planet capture. A progression system, in-game economy, and player interaction have been implemented, making the project a full-fledged multi-module game, not just a Mini App.
Administrative part:
• Telegram admin bot
• Web admin panel
• Search and edit players
• Manage stats and currencies
• Issue / delete items
• Control daily activities
• Manage planets
• Remove players / complete wipe
• Enable maintenance mode
The admin infrastructure allows managing the project, testing balance, and moderating the game without changing the code.
Server part and VDS:
The backend is deployed on VDS to ensure stable operation 24/7. API request processing, data synchronization between the bot, client, and admin panel, as well as secure authorization via Telegram have been implemented.
On the server, the following are implemented:
• REST API
• Working with game data
• Validation of Telegram WebApp
• Generation of start tokens
• Separation of user/admin logic
• Storage of game states
• HTTPS access
VDS serves as the central point of the entire system, ensuring stability and scalability of the project.
Technologies:
Python, Aiogram, Aiohttp
JavaScript, HTML/CSS
Telegram Bot API, Telegram Web Apps
JSON storage, VDS deployment
You can test the project: @StarWarsArenaBot

275 USD Launcher for the Minecraft project
Gaming Apps
1. Upon entering the launcher, there should be a check to see if the game is downloaded. (The path to the game should be C:\Games\MineServer)
2. If the game is not present, instead of the play button, there should be a download button.
… 3. When the download button is clicked, there should be a check for the existence of Java. If it is not present, there should be a download.
4. After that, the official version 1.18.2 of Java should be downloaded.
5. Forge Optifine should be installed immediately with it.
6. After that, a file with the list of mods should be downloaded, etc. (The file can be on GitHub) [Also requested to include three mods and shaders of your choice.]
7. A cancel button during the download.
8. Display a progress bar during interactions.

12. In the settings, there should be an option to open Minecraft in full screen and windowed mode.
13. In the settings, there should be an option to change the amount of RAM. (Default is 8GB.)
14. Additionally, the program should determine how much RAM is on the device. If the device has 8GB or less, it should set 2/3 of the memory.
15. If the user sets more than 3/4 of the RAM, a warning should pop up with confirmation from the user.
16. In the settings, there should be buttons for weak device, standard device, powerful device, and no shaders. (Default is without shaders.)
17. When selecting any device, Minecraft should load with shaders and its own config. (Of course, the config should be loaded once so that the user's settings in the game are not disrupted.)
18. Language settings. Launcher size from 100% to 200%.
19. When the game is running, hide the launcher.

Setting up equipment in Windows 11
Yes, everything is fine. The contractor set up the equipment in Win11, but at the same time, he knows how to code in C# and C++, for this reason, he understands Windows very well. He found the problem and solved it. Before this, I tried to solve the same task with AI and after 12 hours of work, I couldn't manage it. Everything works stably. The person is in touch, communicates, explains what he is doing and why, which is important when the work is being done on your computer. I recommend him for collaboration.
