Blockchain & Web3 Development

Web3 that ships — secure, careful, real.

I build Web3 products with a security-first mindset — smart contracts, decentralized apps, token launches, and wallet integrations on Ethereum and EVM chains. The same detail obsession I bring everywhere, applied where a single bug can be expensive and permanent.

The challenge

Web3 is full of rushed code and copy-pasted contracts — and on-chain, a single bug is permanent and public. Most projects move too fast to catch the mistake that costs them everything.

What’s included
  • Smart contract development in Solidity (ERC-20, ERC-721, ERC-1155)
  • Decentralized app (dApp) front ends with wallet connect
  • Token, NFT, and minting-site launches
  • Thorough testing and security-minded review before mainnet
  • Web3 features integrated into existing sites and stores
  • Clear docs so you understand exactly what you're deploying
What you get
A working, security-reviewed on-chain product
Wallet and dApp UX that regular users can actually follow
A launch you can trust, not a rushed gamble
How we approach it

A clear path from where you are to results.

Step 01

Scope & model

I map exactly what should happen on-chain versus off, and design contracts around clear, minimal rules.

Step 02

Build the contracts

Clean Solidity written to established standards, favoring simple, auditable logic over clever complexity.

Step 03

Test & review

Extensive tests and a security-minded review of every path before anything touches mainnet.

Step 04

Deploy & integrate

Careful deployment, wallet-connected front end, and a UX real users can follow — with docs to match.

Who it’s for
  • Founders launching a token or NFT project
  • Brands exploring real Web3 utility (loyalty, ownership, access)
  • Teams needing smart-contract or dApp work done carefully
  • Anyone who wants Web3 built with security first

Client result
3-week delivery
Peter delivered our whole build in about three weeks — on time, on budget, and better than our spec. His AI-accelerated workflow is the real deal: same quality, a fraction of the usual cost and time.

Questions

Frequently asked.

Which chains do you work with?+
Ethereum and EVM-compatible chains (Polygon, Base, Arbitrum, and similar). I help you pick the right one for cost and audience during scoping.
How do you handle security?+
Careful, standard-based contracts, extensive testing, and a security-minded review before mainnet. For high-value contracts I'll also recommend a formal third-party audit.
Can you add Web3 to my existing site or store?+
Yes — wallet connect, token gating, or minting can be integrated into an existing site or Shopify store without rebuilding it.
