Web3 Engagement Systems Engineer
I Build The Systems
That Make Communities
Stay.
Retention infrastructure for Web3 ecosystems. NFT locking mechanics, participation economies, autonomous game engines, and off-chain token systems - built and running in production on Base.
Case Studies
Systems Built.
Each project is live infrastructure. Not a prototype. Real users, real mechanics, in production.
PunkArcade
Competitive Web3 Gaming Platform
Modular competitive gaming platform on Punkverse. Includes Showdown - a tournament bracket game with NFT matchups and $JUNK staking - and Real // Rebased, a daily prediction game with on-chain burn mechanics. Autonomous cron-driven round lifecycle, deflationary off-chain economy, and full wallet authentication.
View System Architecture →PunkLocker + PP
NFT Locking & Progression Infrastructure
Hybrid on/off-chain staking. Lock NFTs to accrue Punk Power on-chain. Harvest PP via a bridge contract; an event indexer credits the off-chain ledger after confirmation. The retention backbone of Punkverse.
View Architecture →Real // Rebased S2
Autonomous Daily Prediction Engine
Daily Web3 prediction game with fully autonomous round lifecycle. On-chain $JUNK burn-to-play, EIP-191 wallet auth, NFT holder multipliers, streak bonuses, and anti-abuse infrastructure.
View Architecture →$JUNK Economy
Deflationary Game Currency Architecture
ERC-20 on Base with a dual-state model - on-chain claim layer plus off-chain arcade currency. Merkle proof claim system with five operator types. Designed for circulation and burn, not speculation.
View Design →PunkVault
NFT Portfolio Intelligence System
Wallet-connected NFT analytics command center. Historical portfolio replay, smart money tracking, wallet tier segmentation, cross-chain aggregation, and alert systems. Architecture and data pipeline designed.

Persistent Idle Growth Economy
Web-based persistent idle world tied to the Secrets of the World NFT collection (555 items, Ethereum). Plant–harvest–reinvest loop, three-tier currency system, treasure discovery mechanics, and community raffle infrastructure.

Solo founder.
Systems engineer.
15 years shipping.
I'm Chris Nwasike - Lagos-based full-stack engineer. I've spent 3 years building live Web3 engagement infrastructure at Punkverse, a project I took over solo mid-lifecycle and rebuilt around retention.
My stack is PHP/MySQL/JS with ethers.js. I integrate contracts - I don't write Solidity. That's an honest distinction. What I do well: backend systems that compound, economy design that holds up, and retention mechanics that actually keep people around.
Not a contractor-for-hire. An operator who ships complete systems and understands the product layer.

Approach
How I Think
About Systems.
Retention Over Reach
Getting people in is marketing. Keeping them in is architecture. I focus on the second problem - the daily reason to return, progression that feels earned, and an economy that rewards patience.
Systems Over Features
A feature solves one problem once. A system compounds. I design loops - lock → earn → spend → burn → reward - where each action feeds the next. The system does the work.
Honest Scale
Punkverse is indie-scale. I don't overclaim it. What I can demonstrate is that the systems work: mechanics are sound, code ships, architecture scales. That's what transfers to your project.

Building Something That Needs
To Retain Its Community?
If you're working on a Web3 gaming platform, NFT ecosystem, or community product and need engagement infrastructure - not marketing, not vibes, actual systems - let's talk.
