Backend Architecture & System OptimizationVolodymyr Oliinyk
Cover image for Backend Architecture & System Optimization
Stop struggling with technical debt and slow performance.
I help companies build scalable, high-performance backend systems from the ground up or optimize existing ones to handle growing user bases. If your system is lagging or you're planning a complex migration, I’m here to ensure your infrastructure is rock-solid.
What I focus on:
Architecture Design: Shifting from monoliths to Microservices or implementing Event-Driven Architecture.
Performance Tuning: Optimizing PostgreSQL/DynamoDB queries and API response times.
Scalability: Setting up robust backend logic with NestJS that's ready for high traffic.
Security & Reliability: Implementing advanced Auth, data encryption, and automated testing (Jest/Playwright).
Cloud Native: Leveraging AWS and Docker for seamless deployment and management.
The Result: A backend that doesn't break, costs less to maintain, and provides a lightning-fast experience for your end users.
