About

Who is Kennedy.

Software engineer who owns the spec, the schema, the deploy — and the post-mortem. No "that's not my layer."

Started coding at 13 with RPGMaker scripts. Fell into JavaScript at 15 and never came back up.

Shipped my first production system generating real revenue at 18. Today, at 22, I act as de-facto CTO across multiple SaaS in parallel — owning every technical call, every architecture decision, every deploy.

I single-handedly built 25 WordPress plugins for the Univer ecosystem and 6 SaaS products running in production today — payment infrastructure, WhatsApp dispatch at scale, AI-native review systems, omnichannel support. All mine from schema to deploy.

Multi-runtime by design: TypeScript across the full stack, Ruby on Rails 8 for AI-native APIs, Go when latency matters, PHPfor the WordPress ecosystem I've been deep in for years. I architect for scale, not for tutorials.

Off-hours: rock, video games, books. Self-declared nerd.

End-to-end ownership

Schema, infra, interface, deploy, on-call. No "that's not my layer."

HMAC-signed flows, idempotency keys, audit logs, anti-ban, crash recovery — the unglamorous parts that keep revenue safe.

Scale over tutorials

Sub-2KB vanilla JS where it matters, multi-tenant by default, real edge cases over happy paths.
