AI Agent Development

Autonomous agents that plan, call tools, and finish workflows — built for your business logic, not generic chat demos.

Custom AI Agents That Ship

AI agent development is building software that acts toward a goal: researching a lead, processing a document, opening a ticket, or coordinating across APIs. TESARK engineers custom agents with LangGraph, CrewAI, and n8n side-effects — with memory, evals, and human approval where compliance requires it. We are not reselling a platform; we write the orchestration layer that fits your stack. For category context (chatbot vs agent vs agentic workflow) see agentic AI; for wiring agents into an existing product see AI integration services. Clients include fintech, logistics, and B2B SaaS teams globally. PoCs typically land in 4–6 weeks.

Core Capabilities

  • Multi-Agent Orchestration: Specialist agents coordinated by a supervisor — research, execute, verify — with clear handoffs and retries.
  • Tool Use & MCP: Agents invoke your internal APIs, databases, and SaaS tools securely via MCP or custom connectors.
  • Memory & Context: Session and long-term memory so agents maintain state across steps without blowing token budgets.
  • Evals & Guardrails: Automated test suites and output validation before agents touch customer-facing or financial systems.
