Andranik G.

I’m a Senior Backend Engineer specializing in AI agent systems and LLM-powered applications that are built to work reliably in production. I design and develop backend architectures where AI models do more than generate text — they execute multi-step workflows, make structured decisions, call tools and APIs, and interact with databases and queues in a controlled way. My core stack includes Python, FastAPI, LangGraph, LangChain, PostgreSQL, Redis, async task processing, and API integrations. I can help you build: - AI agent systems for automation, decision support, and workflow execution - LLM-powered APIs and backend services - RAG systems with retrieval, validation, and logging - Data-driven platforms with real-time processing - Integrations with external APIs, messaging systems, and databases My approach is engineering-first: I focus on architecture, reliability, observability, and predictable behavior before implementation. I pay close attention to performance, cost efficiency, and security, especially when working with multi-LLM and agent-based systems. If you need an AI backend that is scalable, maintainable, and built for real-world use rather than a quick prototype, I’d be glad to help. Send me a message and let’s discuss your project.
