I build fast, scalable, and production-ready software solutions using Java, Python, and modern backend technologies. My focus is developing reliable backend systems, APIs, and AI-powered tools that solve real business problems.

FAQ
What types of AI applications can you build?
I build AI chatbots, LLM web apps, AI SaaS platforms, RAG systems, AI agents, document Q&A tools, voice AI, and Python automation workflows using LangChain, FastAPI, OpenAI, Claude, and Gemini APIs.
What is included in the $10 Basic package?
A full AI strategy plan — requirements analysis, workflow design, system architecture diagram, and tech stack recommendation. The perfect first step before committing to development.
Which LLMs and AI models do you work with?
OpenAI GPT-4o, Anthropic Claude, Google Gemini, Mistral, Llama 3, and any Hugging Face or Ollama model. I recommend the best fit based on your budget, speed, and privacy needs.
Can you integrate AI into my existing platform?
Yes — I can add AI chatbots, intelligent search, or LLM features to any existing web app or website via REST API, whether it's custom-built or a platform like WordPress or Shopify.
Should I message before ordering?
Absolutely. Every AI project is different. A quick chat ensures we pick the right package, set realistic timelines, and avoid any surprises. I usually reply within a few hours.
