01 — About

Hi, I'm Jaz.
Nice to meet you.

Software developer. Blockchain & AI.

I build blockchain applications — smart contracts, DeFi protocols, real-world asset (RWA) tokenisation and full-stack dApps — along with AI-powered tools that make them smarter and easier to run.

I work mainly in Rust, Solidity, TypeScript and Python, and I care about the basics that matter: clean, well-tested code, sensible security and clear communication from first idea to launch. If you're planning something on-chain, I'd be happy to help you shape it and build it.

> clean code. tested contracts. clear updates.

02 — Services

What I build.

Practical, secure blockchain software, with AI where it genuinely helps.

Smart Contracts

Solidity and Rust contracts written with tests first, an eye on gas costs and proven security patterns such as access control, reentrancy guards and upgrade paths.

/01

DeFi Protocols

Vaults, staking, swaps and yield mechanics, with token economics that are clear and easy to reason about.

/02

RWA Tokenisation

Bringing real-world assets on-chain with ownership tokens, compliance-aware transfer rules and transparent registries.

/03

Full-stack dApps

Decentralised apps from end to end: TypeScript front-ends, smooth wallet flows, indexing and the contracts underneath.

/04

AI-Powered Tooling

Python and TypeScript tools and agents that monitor chains, analyse data, automate repetitive workflows and bring AI features into on-chain products.

05 — Process

How I work.

  1. 01

    Scope

    We agree the goals, the chain and any constraints, so we start from a clear brief.

  2. 02

    Architect

    I map out the contract design, data flow and security considerations before writing code.

  3. 03

    Build

    Test-driven contracts and a clean front-end, using AI tooling to work efficiently.

  4. 04

    Test & review

    Thorough testing, fuzzing and code review. I recommend an independent audit before any mainnet launch.

  5. 05

    Launch & iterate

    We deploy, monitor and keep improving based on real-world use.
