Freelancer profile translated to English.

Description

I develop scalable SaaS backends and bring AI integration into productive operation – not as an experiment, but as real business value.

With over 10 years of PHP/Laravel experience, productive AWS usage (RDS, S3, SQS, Bedrock), and Kubernetes infrastructure, I work on systems that need to grow yet remain maintainable.

In the last two years, I have specifically implemented:

Complete V2.0 architecture of a multi-tenant SaaS platform (Laravel + Vue + AWS + Kubernetes)

AI support assistant based on AWS Bedrock and LangChain – in productive use

RAG pipelines and automations with n8n

CI/CD infrastructure, coding guidelines, and architecture standards for interdisciplinary dev teams

I accept project-based engagements – remote, 2-3 days/week, with a clear scope and real ownership.

Not a ticket-pusher. I think in systems and outcomes.
