I’ve sketched out an original video-game concept that stands or falls on smart, well-integrated artificial-intelligence features. Right now I’m looking for a developer who can help me turn that idea into a playable prototype, starting with a tight vertical slice that proves the AI-driven mechanics work in real time. The headline requirements are simple: • Build an early, playable scene in the engine you feel is most suitable—Unity, Unreal or Godot all fit the brief. • Design and code at least one core AI system that directly shapes gameplay—think believable NPC behaviour, procedural level generation or dynamic difficulty that reacts to the player. We’ll decide together which element delivers the biggest “wow” factor first. • Supply clean, well-commented source files and a short read-me so I can keep the project moving after delivery. A clear, frequent communication style is essential; I’ll share concept art, flow-charts and reference builds the moment we connect so you can estimate t

Please, this must be the first line of your bidd: DEVIWORKS DOLIBARR - ERP CUSTOMIZATION In Dolibarr, I need to: Copy the BOM module and customize it so I can view nested BOMs in a tree view, including descriptions. Currently, the default module only shows the first nested level, but I want to see all of them. Copy the Manufacturing Orders module and add the ability to launch manufacturing orders for a BOM and all nested sub-BOMs in one step. Stocks: I need manufacturing orders and replenishment to pick up product stocks only from one warehouse. For example, if a product is in the “Quality Warehouse,” it cannot be consumed in an MO, and it must be proposed for purchase unless you move it to the “Main Warehouse.” Add product states (for example: Released, Under Modification, Obsolete, etc.). The product state must block manufacturing and purchasing orders. The modifications must be compatible with new releases of Dolibarr, if possible. You must also create clear documentation expla

LlmConnector Development for Copilot and Codex - C# App (incl source available)

Jaroslav delivered quickly and stayed fully engaged throughout the work. He was flexible with changes and adapted to new requirements without delay. Communication was clear, prompt, and constructive. He took ownership of the integration tasks and moved them forward decisively. His implementation added useful functionality with minimal disruption to existing code. Overall, he was reliable and effective, and I would gladly work with him again.
