Description

I am a Platform Architect specialized in stabilizing, restructuring, and scaling complex production systems.

Since 2017, I have taken over live applications used by international teams, reducing technical debt, improving performance, and extending functionality without disrupting operations.

Recent impact includes:

• Laravel API optimizations — up to 3x faster response times by restructuring queries and moving logic from frontend to backend + Elasticsearch

• AI-generated Node.js refactoring — removed redundant logic, consolidated queries, migrated from NoSQL → PostgreSQL, achieving up to 5x faster performance and cleaner architecture

Core expertise:

• Refactoring legacy Laravel & Node.js applications

• Designing scalable APIs & backend architectures

• Database & search optimization (SQL, NoSQL, Elasticsearch)

• Integrating payment gateways and third-party services

• Implementing DAM platforms & advanced permission systems

• Introducing AI-driven features into existing products

• Deployment workflows with Docker & microservices

I specialize in transforming fast-built or AI-accelerated systems into stable, scalable platforms ready for long-term growth.
