Since 2010, I have been architecting production-grade software. Today, I bridge the gap between complex AI capabilities and scalable full-stack infrastructure. With over 16 years of experience, 10,000+ hours logged on Upwork, and a 100% Job Success Score, I specialize in building, deploying, and optimizing AI SaaS platforms and intelligent automation systems. I don’t just write code; I act as a technical co-founder. I help early-stage startups and enterprise teams select the right LLMs, design cost-efficient vector search architectures, and integrate autonomous workflows that drive real business value. 𝐂𝐎𝐑𝐄 𝐀𝐈 & 𝐅𝐔𝐋𝐋-𝐒𝐓𝐀𝐂𝐊 𝐂𝐀𝐏𝐀𝐁𝐈𝐋𝐈𝐓𝐈𝐄𝐒: • AI Engineering & LLM Ops: RAG (Retrieval-Augmented Generation) pipelines, multi-agent orchestrations, custom LLM fine-tuning, prompt engineering, and cost/latency optimization. • Vector Datasets & Frameworks: LangChain, LangGraph, LlamaIndex, Pinecone, ChromaDB, OpenAI API, Anthropic Claude, and open-source models. • Backend & Cloud Engines: Python (FastAPI/Flask), Node.js, secure API design, AWS (EC2, S3, RDS), Google Cloud, and complex database management. • Frontend & SaaS Dashboards: React.js, Next.js, and highly responsive web platforms built for dense data visualizations. • Cross-Platform Mobile: Flutter, React Native, Native iOS (Swift), and Native Android (Kotlin) embedded with client-side or cloud-based AI features.
