AI Agent Development & Software ArchitectureTran Tien Van
I design and build production AI agents that do real work inside your business tools, from the first workflow map to a live, monitored system.
What you get
A workflow audit and agent design: which steps the agent handles, which tools it calls, and where a person approves
An agent built with LangGraph / LangChain, tool calling and MCP integrations, with memory and guardrails
RAG over your documents and data (Pinecone, pgvector, FAISS) so answers stay grounded
Deployment on AWS, GCP or Azure with logging, evals and cost controls
30 days of support after launch
Proof
Alice AI: a LangGraph supervisor routing requests to specialised agents across 70+ MCP tool integrations, on FastAPI and AWS ECS Fargate
OBJX Intelligence: a five-agent enterprise suite with persistent memory (MEM0), five-tier RBAC and 6+ OAuth integrations
Timeline
A single-workflow agent usually ships in 2 to 4 weeks; a multi-agent system in 4 to 8 weeks.
Popular projects
Custom AI agents and AI assistants for support, sales and operations workflows
Multi-agent systems and agentic workflows with LangGraph, CrewAI and the OpenAI Agents SDK
MCP servers and tool integrations that connect LLMs to your CRM, APIs and databases
RAG chatbots and knowledge assistants on GPT, Claude or open-source LLMs
LLM app architecture and AI integration for SaaS products
Pricing
The starting price covers a 2-week first release of one agent workflow. Scope and timeline expand to your requirements, quoted after a free 30-minute call.
