Ghulam A.

I transform raw LLM capabilities into real-world business solutions. From concept to deployment, I build AI systems that deliver measurable results. Recent AI + RAG projects. 1- Architected a high-scale pipeline indexing 500K+ documents using Pinecone and OpenAI. Optimized retrieval via hierarchical chunking, metadata filtering, and hybrid search to minimize hallucination. 2- Engineered a LangGraph-driven agent handling 1K+ daily queries. Implemented stateful orchestration, tool-calling, and self-correction loops for reliable multi-turn automation. 3- Boosted engagement by 40% using cross-encoder re-ranking and dense vector embeddings to maximize Mean Reciprocal Rank (MRR). 4- Deployed LLM microservices for 50K+ users, utilizing Redis semantic caching and LangSmith for observability and latency optimization. What I Build: • RAG-Powered Knowledge Bases: Index millions of documents, deliver answers in milliseconds • AI Agents & Chatbots: Multi-turn conversations, memory, tool use, human-in-the-loop • LLM Integration: Seamlessly embed OpenAI/Claude into existing applications • Custom AI Workflows: LangChain, LangGraph, multi-agent systems • Semantic Search: Find relevant content with 95%+ accuracy using vector databases Why Hire Me? 1- Expert in AI Driven SaaS & MVP development – Helping startups launch and scale 2- Performance-focused development – Optimized, scalable, and secure web applications 3- On-time delivery & agile workflow – Meeting deadlines while maintaining quality Technical Expertise: • Frontend: React, Next.js, Redux, TypeScript, Tailwind CSS, MUI • Backend: Node.js, Express.js, Python, Django, FastAPI, Flask, REST/GraphQL APIs, WebSocket • Database: MongoDB, PostgreSQL, Redis, Firebase • Tools: Docker, AWS, CI/CD pipelines AI-Powered Chatbots & Conversational AI: • AI/LLMs: OpenAI GPT, LangChain, Claude AI, LlamaIndex • Messaging Platforms and Voice Assistants Portfolio Highlights • Maple HRMS (MERN, Microservices): Built a scalable HRMS with granular RBAC, automated workflows, and payroll integrations, reducing administrative overhead by 40%. • Boon ATS (MERN): Revamped frontend performance by 50% and engineered a custom integration engine for seamless applicant tracking and reward automation. • AI-Powered Chatbots: Deployed NLP-driven support bots (BERT/GPT-3.5) cutting response times by 60% for 20+ clients. 📩 Let’s Discuss Your Project!
