Backend-kehitys

With 12+ years of experience in software development, I design and deliver scalable, secure, and maintainable applications for businesses ranging from startups to enterprises. I combine deep technical expertise with a hands-on, problem-solving approach, whether as part of a team or as a freelance partner. I specialize in: Backend & Frameworks: PHP 8, Laravel, C#, Node, Frontend: Vue, Angular, React, HTML/CSS/SCSS, JavaScript, TypeScript, Databases: SQL / NoSQL, Elasticsearch, RavenDB, Cloud & DevOps: Docker, Kubernetes, Google Cloud, AWS, Azure, Terraform, Other Focus Areas: Architecture design, performance optimization (both back- and front-end), CI/CD pipelines, system modernization. As a freelancer, I help companies quickly turn ideas into reliable software solutions for example building new platforms, optimizing legacy systems, and setting up cloud infrastructure. My goal is always to deliver clean code, long-term value, and measurable business impact.
