📌 LLM Implementation, RAG & Agentic Workflows
✅ Proficient in deploying and fine-tuning Large Language Models (LLMs) such as Llama 3, Claude, Mistral, Phi-3, and OpenAI GPT models for diverse conversational and reasoning applications.
✅ Built advanced Retrieval-Augmented Generation (RAG) systems with custom chunking, hybrid (dense + keyword) search, and vector databases like Pinecone, Weaviate, ChromaDB, and FAISS for accurate, traceable answers over large datasets.
✅ Architected multi-agent orchestration frameworks using LangChain, LangGraph, OpenAI Agent SDK, and Mastra — designing Planner, Retriever, Executor, and Feedback agents for memory-rich workflows.
✅ Engineered Model Context Protocol (MCP) servers enabling unified natural-language querying across infrastructure, security, and code-quality systems.
✅ Expertise in parameter-efficient fine-tuning (LoRA) for domain-specific performance without overloading infrastructure.
📌 Enterprise AI & Observability Platforms
✅ Developed Natural-Language-to-SQL agents integrating DevSecOps tools like Datadog, Snyk, SonarQube, and Qualys into a single conversational layer.
✅ Built real-time vulnerability correlation engines and automated root-cause-analysis pipelines for enterprise agentic platforms (10+ integrated tools).
✅ Delivered production GenAI systems for enterprise clients through the Andela Talent Network, including Scholastic and News Corp.
📌 Conversational AI & Voice Agents
✅ Expert in real-time voice AI agents using the OpenAI Realtime API, ElevenLabs, and Twilio Voice for natural, low-latency phone conversations.
✅ Built end-to-end voice bots with interruption handling, emotion detection, transcription (Whisper), and multi-language support.
✅ Designed WebRTC voice pipelines with sub-200ms latency using Twilio Media Streams and FastAPI + AWS Lambda backends.
✅ Created conversational IVR systems blending traditional telephony with modern AI for enterprise contact centers.
📌 Document Intelligence & Computer Vision
✅ Engineered LLM-driven document intelligence pipelines using VLMs (Qwen2-VL, Donut) and YOLOv10 for zero-shot, generative parsing of complex layouts.
✅ Built intelligent document-routing pipelines with a custom EfficientNetV2 architecture achieving 95% top-2 accuracy in PDF page classification before generative processing.
✅ Trained transformer-based OCR models (with Tesseract, EasyOCR, Textract) to extract high-fidelity text from degraded, noisy scans and feed clean context downstream.
📌 Generative AI for Business Applications
✅ Delivered enterprise generative AI using Stable Diffusion, MimicMotion, DWPose, ControlNet, and ComfyUI for branded content, avatar animation, and video-to-video generation.
✅ Integrated generative models with chatbots for document generation, image-based responses, and personalized outputs.
📌 Cloud, Backend & Deployment
✅ Scalable deployments on Azure AI, AWS, and GCP — including Azure Cognitive Services (Speech-to-Text, Text Analytics, Computer Vision).
✅ Production backends with FastAPI, Docker, GPU scaling, and custom high-performance local ML hardware.
