I am a futuristic software engineer.
I am interested of distributed systems, parallelism, concurrency, lockfree algorithms, database architecture and internals, programming language design, algorithms and data structures. You shall find various straightforward, simple implementations of various algorithms on my Github profile. Change the dropdown types field to 'Sources' to see things I created. My code is Zero Clause BSD licenced.
Are you looking for a devops software engineer? Send me an email.
I'm a devops software engineer with skills in Python, Java, Javascript, Terraform. See my personal-manifesto.
Some highlights of what I am building:

I wrote a toy amd64 in Python and JIT compiler in C and the beginnings of a browser engine
I implemented a three way merge diff algorithm based on Myers algorithm. A distributed pseudo multimodal keystore database and a mazzle build server. I also implemented a merkle CRDT and part of the YATA text merging algorithm.
