Hassan Abbas

I help startups and businesses design, build, and deploy production-ready AI solutions using Machine Learning, Generative AI, LLMs, RAG, AI agents, NLP, computer vision, and workflow automation.

I have 2+ years of hands-on experience building end-to-end AI systems, from model integration and retrieval pipelines to backend APIs, databases, automation workflows, deployment, and production optimization.

My services include:

• Custom AI and LLM applications using OpenAI, Anthropic Claude, Google Gemini, Hugging Face, and open-source models
• RAG systems with semantic search, hybrid retrieval, embeddings, re-ranking, FAISS, pgvector, and vector databases
• AI agents and multi-step agentic workflows using LangChain and custom orchestration
• AI chatbots and conversational AI systems for customer support, sales, HR, and internal knowledge bases
• Voice AI agents using Twilio, Retell AI, transcription, lead qualification, and workflow automation
• Document AI, OCR, intelligent document processing, information extraction, and document search
• Machine Learning and Deep Learning solutions using Python, PyTorch, TensorFlow, and scikit-learn
• NLP solutions including text classification, sentiment analysis, entity extraction, embeddings, and summarization
• Computer vision solutions using YOLO, ArcFace, OCR, and deep learning models
• FastAPI, Flask, NestJS, and Node.js backend development for AI-powered applications
• Docker, Kubernetes, CI/CD, cloud deployment, Redis, PostgreSQL, and production AI infrastructure
• n8n and API-based automation integrating AI with CRMs, communication platforms, and business systems

I focus on delivering scalable, secure, maintainable, and production-ready solutions rather than simple prototypes.

If you need an AI-powered SaaS product, RAG system, AI agent, ML model, automation workflow, voice AI solution, or custom AI integration, I can help take it from idea to deployment.
