O mnie
I'm a Senior Full Stack Engineer with 10+ years of experience building scalable web applications, cloud platforms, and distributed systems for startups and established companies across SaaS, healthcare, eCommerce, fintech, and insurance.
My expertise spans Node.js, TypeScript, Python, C#/.NET, and Go, along with modern frontend technologies such as React and Next.js. I've designed and built APIs, microservices, event-driven architectures, and cloud-native solutions on AWS and GCP. More recently, I've helped teams integrate AI capabilities using OpenAI, LangChain, RAG pipelines, and intelligent automation workflows.
Beyond software development, I have strong DevOps experience with Docker, Kubernetes, CI/CD pipelines, cloud infrastructure, and production operations. I enjoy taking ownership of projects from architecture to deployment, solving complex technical challenges, and delivering reliable solutions that create real business value.
