Specialized Services
With over 7 years of experience in backend development and distributed systems, I specialize in building high-performance, scalable solutions using modern technologies and best practices. My focus is on delivering robust, maintainable systems that solve complex business challenges.
Architecture & Design Patterns
I implement a clean, maintainable architecture focusing on scalability and maintainability:
N-Tier Architecture
Organized in DB, Data, Business, and Service layers for clear separation of concerns
Repository Pattern
For database abstraction and clean data access
Unit of Work
Managing database transactions and ensuring data consistency
Strategy Pattern
For flexible, interchangeable algorithms in notifications, processing, and authentication
Backend Development & API Design
Expert in building robust backend systems using ASP.NET Core and C#. Specializing in RESTful APIs and GraphQL endpoints that handle high traffic with optimal performance. Proven track record of reducing system resource usage by 60% through efficient query optimization and caching strategies.
Real-time Systems & Message Processing
Design and implementation of scalable real-time solutions using WebSockets and message queues. Built high-performance systems handling 500+ concurrent users with Redis caching and RabbitMQ for efficient message processing. Expertise in implementing real-time comment systems and notification delivery.
System Architecture & Database Design
Architecture design focusing on scalability and maintainability. Extensive experience with PostgreSQL and SQL Server database optimization, implementing efficient caching strategies, and designing secure authentication systems with JWT. Specializing in high-availability distributed systems.
Security & Performance Optimization
Implementation of robust security measures including JWT authentication, rate limiting, and daily backup systems. Experience in performance optimization through query tuning, caching strategies, and load distribution. Focus on maintaining high security while ensuring optimal system performance.
