I build AI voice agents and multi-agent systems that replace manual work, 15+ deployed for clients, not demos. Recent agents cut clients' manual workload ~60% and LLM token costs 70–90%. Over the past year I've designed agentic systems for a SaaS company serving 50+ enterprise clients, LangGraph/LangChain Text-to-SQL agents with tenant-safe execution, a multi-agent business-automation pipeline (dynamic pricing, invoicing, workflow orchestration) running on Azure, and a Claude MCP–powered BI automation layer that cut reporting time 50%. What I can build for you: 🎙️ Voice AI agents & phone bots: real-time pipelines (Gemini Live API ~ GPT-4/Claude ~ ElevenLabs, on Vapi or Retell) for support, booking, lead qualification, and 24/7 reception. 🤖 Multi-agent workflows: LangGraph, CrewAI, and AutoGen orchestration with tool use, memory, routing, and guardrails for end-to-end automation. 📚 Agentic RAG systems: accurate, grounded answers over your own documents and data (ChromaDB, FAISS, Pinecone), with strict policy enforcement. 👁️ Computer vision: real-time object detection, tracking & segmentation (YOLO, SAM) and OCR for monitoring, compliance, and document processing. ⚙️ LLM fine-tuning & cost reduction: QLoRA/PEFT and LLM routing to cut inference cost without losing quality. Background: CS degree from FAST NUCES (Dean's List of Honours), Finalist at NETSOL, biggest corporate hackathon and Anthropic Certified Engineer. Tell me what you're trying to automate and I'll reply with exactly how I'd build it.

I'm a Software Engineer with 3+ years of professional experience shipping 50+ games with 100M+ combined downloads. I've worked with international publishers including Voodoo and built products across mobile, FPS, AR, and AI tooling. 🎮 Game Development (Unity / C#) I build complete game systems from scratch — FPS mechanics, roguelite progression, multiplayer foundations, mobile-optimized UI, and physics-based gameplay. I've shipped hyper-casual prototypes for Voodoo, contributed to titles at Game District, and currently lead development on a co-op FPS roguelite targeting Steam. What I deliver: — Gameplay systems, character controllers, AI behaviours — Mobile optimization for iOS and Android — Fast prototyping with publisher-ready quality — Bug fixing, performance profiling, and legacy code cleanup 🤖 AI Engineering & LLM Integration I build AI-powered tools and integrate LLMs into real workflows. I created EditorMind MCP — an open-source tool that gives AI agents like Claude direct control over the Unity Editor, enabling autonomous code writing, error querying, and file management inside Unity. It uses a C# HTTP listener, Node.js MCP server, and ships self-contained binaries for Windows, macOS, and Linux via GitHub Actions CI/CD. What I deliver: — MCP server development and LLM tool integration — AI agent workflows using Claude, OpenAI APIs — Python scripting and automation pipelines — AI-assisted development tooling for game engines 💻 Web & Software Development Comfortable building full-stack web projects including Next.js apps, REST APIs, and developer tools. I built and deployed my own portfolio site (Next.js 14, Vercel, cyberpunk aesthetic) and have experience with GitHub Actions pipelines and CI/CD workflows. Previous clients say: "Raheeb is an amazing, talented, hard-working developer with deep gaming industry knowledge. His dedication to the job and pure talent allowed the work to be finished perfectly." Available full-time · Response time under 30 minutes · Open to long-term contracts
