I'm a Python Full Stack & AI Engineer with 6+ years of experience building scalable web applications, AI-powered products, and production-ready backend systems. I specialize in Python, FastAPI, Django, React, Next.js, PostgreSQL, Docker, REST APIs, and cloud-native application development, with a strong focus on integrating AI into modern business software.

I design and build AI agents, LLM applications, RAG systems, conversational AI, workflow automation, and AI-powered SaaS platforms that automate business processes, improve customer support, streamline document processing, and enhance operational efficiency.

My AI expertise includes OpenAI, Claude, Gemini, LangChain, LangGraph, LlamaIndex, MCP, vector databases, embeddings, prompt engineering, function calling, structured outputs, semantic search, hybrid retrieval, reranking, and multi-agent workflows. I develop production-ready AI systems with secure architecture, monitoring, validation, and human approval workflows.

As a full stack engineer, I build scalable applications using Python, FastAPI, Django, React, Next.js, TypeScript, Node.js, PostgreSQL, MongoDB, Redis, Docker, and cloud platforms. My work includes secure REST APIs, authentication, background processing, third-party integrations, and maintainable software architecture.

Projects I've delivered include:

• AI agents with tool calling and workflow automation

• Enterprise RAG assistants with citations and access control

• AI chatbots for web, Slack, WhatsApp, and internal platforms

• Voice AI assistants for customer support and appointment booking

• AI document processing for invoices, contracts, and forms

• Multi-tenant AI SaaS platforms with analytics and administration

• CRM automation and integrations with HubSpot, Salesforce, GoHighLevel, and custom platforms

I enjoy building products where AI and software engineering come together. Whether developing FastAPI or Django backends, React/Next.js frontends, or LLM-powered AI applications, I focus on delivering secure, scalable, and production-ready solutions that solve real business problems.
