About Kristiyan
I am a Senior Software Engineer specializing in AI-powered applications, full-stack development, cloud solutions, and API integrations.
I help businesses build reliable, scalable, and maintainable software products, from modern web applications and backend systems to cloud-based platforms and automation workflows.
My core stack includes JavaScript, TypeScript, React, Next.js, Node.js, Python, PostgreSQL, MongoDB, AWS, Azure, and REST API integrations. I am comfortable joining existing teams, improving legacy systems, building new features, and taking ownership of full development workflows from architecture to deployment.
I focus on clean code, clear communication, and business-oriented delivery. My goal is always to build software that is not only technically solid, but also practical, maintainable, and useful for the business.
I am available for full-stack development, AI integration, backend/API work, cloud deployment, and long-term engineering support.
