Project details

You will get a production-ready RAG & LLM backend system designed for real-world deployment, not demos. I build scalable AI backends that connect large language models to structured and unstructured data with reliability, security, and performance in mind.

This project is built for teams that need more than a simple chatbot. Whether you're integrating AI into an internal tool, customer-facing platform, analytics system, or enterprise workflow, the system is designed to be modular, secure, and extensible.

Each tier represents a complete solution for a defined project scope. Smaller tiers cover focused AI integrations with controlled data sources. Higher tiers support multi-source ingestion, hybrid retrieval, scaling strategies, monitoring, and production hardening.

The result is a stable, API-driven AI backend that can be deployed, maintained, and extended confidently.

30 minute consultation "Deep expertise in LLMs & Program Systems. Highly recommended."
I requested a technical review of my documents(LLMs, Program Synthesis, Reinforcement Learning), and the quality of his feedback exceeded my expectations. He provided detailed and profound answers specifically on the drafts I submitted.

He clarified complex concepts regarding LLM and Program Synthesis, advising on the accuracy of terminology, current trends, and technical feasibility. His insight into graduate-level research topics, including specific papers and research direction, was incredibly impressive. I look forward to working with him again.

I build production AI systems and tools for great performance, accuracy and reliability: LLM inference and runtimes, RAG pipelines, and agentic systems. Faster and correct code analysis and transformations within compiler/runtimes for verification and optimization purposes.

Recent work: a local LLM runtime that saved 541 seconds through KV cache optimization, a RAG classification system at 95%+ accuracy, and an AI agent querying SQL databases with millions of records.

Whatever you're building, I've likely engineered the layer underneath it.

• Local deployment: llama.cpp, Ollama, vLLM, GGUF, TensorRT-LLM, MLX
• Models: LLaMA, Mistral, Phi, Qwen, DeepSeek, Hugging Face Transformers
• Optimization: KV cache, speculative decoding, continuous batching, tensor & pipeline parallelism
• Fine-tuning: LoRA, QLoRA, PEFT, RLHF, DPO, distillation, quantization
• GPU: CUDA, cuDNN, TensorRT, multi-GPU, distributed inference

𝗥𝗔𝗚 & 𝗥𝗲𝘁𝗿𝗶𝗲𝘃𝗮𝗹

• Vector stores: FAISS, Pinecone, Milvus, ChromaDB, Qdrant
• Search: hybrid search, dense retrieval, BM25, GraphRAG, knowledge graphs
• Embeddings: OpenAI, Gemini, Mistral, open-source models
• Delivered: real-time RAG classification system, 95%+ accuracy in production

𝗔𝗴𝗲𝗻𝘁𝗶𝗰 𝗔𝗜

• Frameworks: LangChain, LangGraph, MCP
• Capabilities: tool calling, function calling, memory systems, reflection, self-correction, planning
• Delivered: AI agent over SQL databases with millions of records, 5-star review

𝗦𝘆𝘀𝘁𝗲𝗺𝘀 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴

The layer most AI engineers never touch, and the reason my systems hold up when others break.

• Languages: Python, Rust, C++, C
Compiler optimizations, static analysis, instrinsics, loop unrolling, verification
• Runtime: CUDA, cuDNN, NCCL, LLVM, MLIR, JIT, AOT
• Low-level: SIMD, AVX, SSE, OpenMP, OpenCL, lock-free programming, POSIX, epoll
• Profiling, benchmarking, kernel optimization, distributed training

𝗪𝗵𝘆 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵 𝗺𝗲

① PhD in compiler and static analysis: I know if the system is right, not just if it runs
② 10 years at Microsoft: I know what production reliability actually requires
③ Full-stack depth: from CUDA kernels to agent orchestration to RAG pipelines
④ Every project delivered, every client satisfied

I work with funded startups, scale-ups, and engineering teams building serious AI infrastructure across any industry.
