Independent Senior / Lead Software Engineer

As an independent Senior/Lead Software Engineer working on a freelance basis, I help businesses design and implement scalable, maintainable backend systems using Kotlin. I specialize in cloud-native architectures, microservices, and event-driven patterns, ensuring high-quality results tailored to meet business needs. I lead by example, coaching developers within my team to improve their skills while driving projects forward.

I have worked with leading organizations to deliver impactful solutions, leveraging my AWS and Azure certifications and extensive expertise in building secure, efficient systems. I am also an AWS Community Builder in the Serverless category, contributing to the AWS community by sharing insights and best practices in cloud-native development.

In addition to software engineering, I provide Kotlin training sessions to help teams enhance their skills and productivity. My training programs are based on practical, real-world experience and include content from my book, Kotlin Crash Course—a comprehensive guide to learning Kotlin, from basics to advanced concepts. Learn more about my tailored training programs on the Training page.

Beyond my immediate projects, I write about Kotlin and cloud-native solutions on my blog and share insights at conferences like KotlinConf, Voxxeddays and Kotlin Dev Day Advanced. Check out my upcoming talks.

Outside of work, I enjoy running, yoga, cross-country skiing, and spending time with my kids & family.
