About
Abdullah Zakariyya
I'm an engineer who works across four fairly different disciplines, and I like keeping the seams between them clean. Most of what I build shares one instinct: make the trust-critical part small, explicit, and easy to reason about — then let everything else be downstream of that discipline.
The home page is the honest version of this résumé: a star map of real projects, grouped by the field they belong to. Bigger stars are the work I've invested the most in; a glow means there's a written story behind it. Open any project to read the case study, and follow it into the companion write-ups.
Web3
Non-custodial settlement, on-chain indexing, NFT tooling and smart contracts — systems where the trust boundary has to stay small and auditable.
Security
Mobile threat defense and forensic artifact matching — reading device signals and checking them against structured threat intelligence.
Commerce
Nigeria-focused marketplaces on a repeatable Next.js + Mongo/Redis reference architecture I clone and adapt across products.
Tools / Labs
Productivity tools, marketing sites, and sandboxes for learning — where new stacks and ideas get a first run.
