I'm a Senior Backend Engineer with 6+ years of experience building scalable, production-ready systems. My primary focus is on the Node.js ecosystem (TypeScript, NestJS, Express), where I specialize in creating modular, efficient, and secure applications.

My passion lies in engineering fast and reliable systems, especially where blockchain, APIs, and scalability intersect. I have extensive experience developing multi-currency crypto payment gateways, designing secure wallet services, and implementing real-time transaction monitoring.

• Backend Architecture: Designing and implementing scalable microservices, modular systems, and clean architecture.
• Blockchain & Crypto: Building secure crypto payment gateways, wallet services (UTXO & Account-based), and real-time monitoring solutions.
• API Development: Crafting efficient and developer-friendly APIs using REST, GraphQL, JSON-RPC, and WebSockets.
• Performance Optimization: Leveraging database indexing, caching strategies (Redis), and message queues (RabbitMQ) to build high-performance systems.
• TDD & CI/CD: Advocating for test-driven development and automating deployment pipelines with tools like GitHub Actions.
