Custom LLM Application Development
End-to-end LLM-powered applications: system prompt engineering, context window optimization, streaming response implementation, conversation state management, token cost management, multi-model routing. Foundation models: GPT-4o, Claude 3.5 Sonnet, Gemini 1.5 Pro, Llama 3, Mistral.
RAG System Development
Complete RAG pipelines: document ingestion and chunking, embedding model selection, vector database setup, semantic and hybrid retrieval, reranking, and LLM response generation with citation grounding. For knowledge Q&A, support AI, contract analysis, and compliance lookup.
AI Chatbot Development
Production-grade chatbots with multi-turn conversation, persistent memory, tool use/function calling, human escalation with context handoff, multilingual support, channel integration (web widget, Slack, Teams, WhatsApp), and analytics dashboards.
AI Agents Development
Autonomous agents using ReAct framework, tool-use patterns, and structured output schemas. Research agents, data processing agents, customer interaction agents, and coding agents with human-in-the-loop checkpoints and full audit logging.
AI Automation Pipelines
Document processing and generation at scale: invoice/contract extraction, report generation, personalized content at volume, email triage, meeting summarization, and regulatory classification batch or real-time with confidence scoring.
LLM Fine-Tuning & Model Customization
Supervised fine-tuning (SFT) and RLHF on open-source models (Llama 3, Mistral, Phi-3) for self-hosted deployment. OpenAI fine-tuning on GPT-3.5 and GPT-4o-mini for cloud-hosted customization when RAG accuracy is insufficient.
AI Integration into Existing Products
AI feature architecture design, LLM API integration, streaming UI components (React), token usage monitoring and cost controls, prompt versioning and A/B testing infrastructure, and AI feature flags for controlled rollout.
