Community product
ActiveCommunities rank anything.
A full-stack rankings platform where communities create, share, and vote on top-10 lists — music, movies, tech, travel — rebuilt multiple times as the product vision matured.
My role: Built
Nzubechukwu Cyprian.
Pharmacy Software AI Full-Stack Dev
I study Pharmacy at the University of Nigeria, Nsukka. Outside the lecture hall I build software — full-stack products, AI experiments, and open-source contributions — and I treat both like they matter, because they do.
Now
Currently building
A living product ecosystem — community products, developer tools, AI systems, fintech, media, and infrastructure. This is what's alive right now, not a graveyard of past work.
Fintech · Ecosystem product
BuildingSavings circles, on rails.
Digital savings circles built around transparent, programmable financial infrastructure — modernizing rotating savings groups (Ajo, Esusu, ROSCA) with on-chain escrow and automated payouts.

Developer tool · Ecosystem product
MaintainingKnow a domain's worth.
A domain appraisal engine that evaluates domains across 16 dimensions and produces a dollar-value estimate — shipped as a CLI, a terminal UI, and an HTTP API.

Media · Ecosystem product
ExploringMovieDB
Find your next film.
A film discovery experience built around structured movie data — search, details, and watchlist-oriented browsing.
My role: Built
Every item above states its status and exactly what my role was. Cloned or forked repositories never appear here — a repository is evidence, not ownership.
The ecosystem
O4A INNOVATIONS
A holding company. Building and operating businesses.
O4A INNOVATIONS is a holding company that builds, operates, and invests in businesses across technology, media, and services. Its first operating company — Cocor Tech — is where the products Cyprian builds and operates live.
Most builders stop at the product. O4A exists to go further — to take things that work and run them like businesses, across technology, media, and services.
Build
Found and build businesses across technology, media, and services — from first product to operating company.
Operate
Run what we build with real ownership: systems, teams, and businesses that keep working after launch.
Invest
Put capital and engineering into adjacent opportunities that fit the businesses already being built.
Ventures under this roof
- Cocor Tech ↗Operating company that builds, acquires, and scales digital assets — Products, Agency, and Brand Assets divisions.
Co-founder: Nzubechukwu Cyprian — Co-founder. Builds software and ships products inside the O4A ecosystem while studying Pharmacy at UNN.
Contribution
Open source
Contribution over ownership — work done in other people's repositories, with evidence. A repository is proof of work, not proof of authorship.
Drips Wave · Open-source contribution
Stellar ecosystem open source
Contributing to open-source repositories across the Stellar ecosystem through Drips Wave — recurring one-week contribution sprints where contributors earn points and rewards for merged work.
GrantFox · Open-source contribution
Stellar open-source collaboration hub
Contributing to open-source issues and bounties surfaced through GrantFox, a community-run collaboration hub connecting contributors with Web3 and open-source opportunities on the Stellar ecosystem.
I started coding in 2022 on an Android phone with Termux — no AI assistant doing the work, no laptop, just learning by figuring things out. Later, a PC gave me room to build bigger things.
The phone was where I started. The PC was where I started scaling. What began as small experiments grew into full-stack development, products, AI, and open source — all while I studied Pharmacy at UNN. Both are real, and both are me.
Thinking
Writing
Notes on engineering, AI, products, open source, and the Pharmacy × Tech life — original, first-person, self-hosted.
The model is not the product
Everyone debates which model is smartest. Almost nobody talks about the ninety other things standing between a prompt and a shipped feature.
AI
Naming things is the whole job, sometimes
Most codebases don't have a naming problem — they have a thinking problem that shows up in their identifiers.
Software engineering
Shipping is a skill, and I practised it badly for years
Finishing things is not a personality trait — it's a practice with techniques. The ones that turned my graveyard of half-projects into shipped products.
