· an engineer's notebook
I’m Yahampath, a software engineer. Point me at anything.
I build web systems end to end: the interface, the services behind it, and the deployment around both. Lately that means putting language models into production and automating the manual work around them. Healthcare, education, retail, transport, finance: most of what I have built is still in daily use.
