Frequently Asked Questions

How long does a typical project take?

A simple bot or integration takes 1-2 weeks. A full SaaS platform or complex AI system typically takes 4-8 weeks. Timeline depends on scope — I provide a detailed estimate after the free discovery phase.

What is your development process?

I follow a structured process: Discovery (understanding the business problem), Architecture (system design and stack selection), Development (iterative builds with regular demos), Launch (deployment and testing), and ongoing Support. You see working software every week.

Do you work with international clients?

Yes. I am based in Barcelona and work with clients worldwide. Communication is in English, Spanish, or Russian. I use Telegram, WhatsApp, and email for project coordination. Time zones have never been a problem.

What technologies do you use?

Primary stack: Python, Django, Django REST Framework, PostgreSQL, Redis, Celery, Docker. For AI: OpenAI API, LangChain, AI agents. For integrations: Telegram Bot API, Stripe, CRM systems, Google Shopping.

Can you integrate AI into my existing system?

Yes. I specialize in embedding AI (OpenAI, LangChain) into existing business workflows — chatbots for support and sales, content generation, recommendation engines, and custom AI agents. Integration can be done without rebuilding your current system.
