About
I'm Selwyn — a software engineer writing about the systems I build: distributed backends in Java and Spring Boot, event pipelines on Kafka, and the investment management and digital-asset platforms they sit inside.

Editorial standards
Original and first-hand. Articles come out of work I have actually done. Where a claim rests on someone else's work it is cited and linked.
No paid placement. Nothing on this site is sponsored, and no vendor has ever paid for a mention. There are no affiliate links.
Corrections are visible. If a post is wrong, it gets fixed and the correction is noted rather than silently edited away. Report one at contact@scalefirst.org.
Employer independence. Views here are my own and are not those of any employer or client, and no confidential material from any of them appears in an article.
