FinlandWhat I'm looking for
I am a Senior Full Stack Engineer focused on building reliable, scalable web platforms that deliver measurable product value. I bridge frontend and backend development to turn complex ideas into clean, maintainable code and interactive user experiences.
At Enterpret I designed and optimized data pipelines, implemented real-time alerts, and built AI/ML integration layers to classify and surface user feedback, while improving backend performance with Redis caching and query tuning.
I have led feature development for product editors, optimized site performance through code-splitting and lazy loading, introduced logging and monitoring, and mentored junior developers to improve code review practices and cross-team collaboration.
