Resume

As a skilled software engineer with expertise in distributed systems design and implementation and scalability, I have contributed to both commercial and open-source projects. My experience in designing and deploying cloud-native architectures, particularly in big data environments, has been invaluable in helping organizations achieve their engineering goals.

My track record of delivering successful projects and technical leadership have made me a valuable asset to teams. I possess expertise in distributed systems, systems engineering, networking, virtualisation, operating systems, performance, concurrency and functional programming.

I also like about various topics including Kubernetes, compilers and distributed systems in general to my blog.

Projects

• Sila programming language (2023 - Present)

  • Sila is a programming language that, like all new languages, has somewhat optimistic aspirations. Implemented in Common Lisp, it includes sophisticated type system and garbage collection. Currently targeting x86-64 and aarch64. Sila’s development log available here: https://topikettunen/blog/tag/sila

• TOPS (Topi’s Own Plugin Suite) (2019 - Present)

  • TOPS is a work in progress plugin suite for VST/AAX/AU audio plugins mainly created for various personal needs. This includes different DSP and MIDI tools. These have been mainly built as closed source but recently I have started the process of open sourcing what I can.

Work Experience

Polar Squad
