I am a Senior Software Engineer with 8+ years of experience designing and developing reliable, scalable web and backend applications. My main expertise is backend engineering with Node.js, TypeScript, NestJS and Express, combined with strong knowledge of modern frontend technologies such as React, Next.js, Angular, JavaScript, HTML5 and CSS3.
I have extensive experience designing REST APIs, backend architectures, authentication and authorization systems, third-party integrations, and business-critical applications. I work confidently with PostgreSQL, MySQL and MongoDB, including database modelling, complex queries, indexing, transactions and performance optimization. I also use Redis for caching, queues and improving application performance.
My cloud and infrastructure experience includes AWS services such as Lambda, API Gateway, DynamoDB and CDK, as well as Docker, Docker Compose and CI/CD pipelines. I am familiar with microservices, asynchronous processing, RabbitMQ, event-driven architectures and distributed systems.
I have contributed to projects in fintech, e-commerce, marketplaces and startups, working across the full development lifecycle: technical design, implementation, testing, debugging, deployment, monitoring and continuous improvement. I pay particular attention to code quality, scalability, security, maintainability and performance.
I am comfortable working independently or as part of distributed international teams. I collaborate effectively with developers, product managers and designers, and I can quickly understand existing codebases and business requirements. I also have experience contributing to open-source projects.
I am particularly interested in building scalable digital products, cloud-native applications, fintech solutions, automation and AI-powered features. I enjoy solving complex technical problems, improving existing systems and continuously learning technologies that can create measurable business value.
