Python / PHP / Laravel / Node.js / AI / RAG

Senior backend and AI developer

I build AI assistants, backend systems, custom CRM platforms, Telegram bots and API integrations with Python, PHP/Laravel and Node.js. I work on focused improvements and MVPs as well as complex systems with integrations and business logic.

You do not need a finished specification. We can start with the business outcome, define the smallest useful solution and choose a stack that fits the task.

Core expertise

Have a problem but no detailed specification?

Describe what happens today and what result you need. You do not have to select the technology, database or architecture in advance.

I will examine the workflow, propose an implementation and break it into clear stages. If an MVP or a small integration is enough to test the idea, we can begin there.

From a focused task to a complete system

I handle individual improvements, prototypes and integrations as well as larger systems. Before development starts, I define the smallest scope that can produce the required result within the available budget.

Technology selected for the task: Python · PHP / Laravel · Node.js · AI / LLM · RAG · Qdrant · Telegram · REST API · MySQL / PostgreSQL · Redis · Docker

My name is Andrey. I am a senior backend and AI developer with over 15 years of experience. I work with Python, PHP/Laravel and Node.js, building AI and RAG systems, custom CRM platforms, API integrations, Telegram services and software with complex business logic.

I enjoy projects where the work starts with understanding the process and the desired outcome, not simply implementing a finished specification. I select the stack and architecture after the problem is clear.

I take on focused improvements and MVPs as well as complete systems that need ongoing support and development.
