Freelancer profile translated to English.

Description

Senior Software Engineer with 10 years of experience in designing, developing, and scaling SaaS, AI, and cloud platforms. I have consistently held architecture responsibilities: designing microservices distributed systems, aligning business and technical stakeholders, and driving the adoption of new technologies.

Expert in cloud architecture (GCP, Terraform, Docker, Kubernetes), microservices, and data pipelines (PostgreSQL, BigQuery). Strong experience in generative AI (LLM, RAG, semantic search) and integrating AI into enterprise systems.

Excellent communication skills, with a strong background in mentoring engineers and interacting directly with clients. Agile certified (PSPO), strengthening my abilities in client workshops, pre-sales, and product scoping.

In parallel: developing apps ranked Top 5 on app stores, selling a Document AI project, regularly writing about generative AI, and publishing open-source experiments – experiences that enhance my ability to explain complex technologies and demonstrate their concrete value.
