01 / SELECTED WORK

From the first idea
to the last detail.

Product thinking, full-stack software, and on-chain systems.

ENTERPRISE / WEB301
SIMBA Blocks

A product’s story.
Made traceable.

DIGITAL PRODUCT PASSPORTS

SIMBA Chain

Product engineering

Making complex blockchain tools feel clear and usable.

Inside the project

Product engineering for SIMBA’s Blocks and digital product passports, with a focus on product records, schemas, permissions, and the interfaces that connect them.

The work combines TypeScript, reusable components, and product decisions that make complex enterprise workflows easier to use and maintain.

CAMPAIGNS · PROFILES · REWARDS

Clasho

Full-stack development

Connecting campaigns, community, and participation.

Inside the project

A community product with campaigns, profiles, account connections, and rewards. Full-stack development connects the user experience with the services and account flows behind it.

From the first visit to a completed profile, the focus is a consistent experience across a product with plenty happening underneath.

IDENTITY MEETS ON-CHAIN CLAIMS

EPIK

On-chain systems

Connecting identity, wallets, and on-chain claims.

Inside the project

A campaign and claim platform combining a distinctive visual experience with Solana wallet connections, social identity, and a Merkle-based claim system.

The implementation brings together authentication, deterministic claim tooling, and an Anchor distributor. An ongoing build, with production release gates still being worked through.

Co-founder

Helping teams turn technical ambition into working products.

Inside the practice

I co-founded WebThree Consulting to help teams move from an idea to a working product, connecting product decisions with engineering delivery.

The practice brings together software development, Web3 integrations, and smart-contract security work, with a hands-on approach from scoping through implementation.

02 / A LITTLE ABOUT ME

Curiosity is
the common thread.

Siddig — or Ziggy.

I like the complicated stuff.
I just don’t think it should
feel complicated.

I’m a Web3 Product Engineer, senior software developer, and co-founder of WebThree Consulting, based in London. My work spans product decisions, full-stack development, and blockchain systems.

From community work at POA Network to product engineering with SIMBA Chain and building through WebThree, I connect what people need with the software that delivers it: interfaces, services, data, and on-chain logic.

These days, that means building products, reviewing systems, and exploring where AI can make the work better. I care about clear architecture, useful software, and taking a product from an early idea through implementation and beyond.

03 / HOW I WORK

From product thinking
to working systems.

01

Understand the product.

Find the actual problem. Work out what matters to the people using it. Make the scope clear before making it bigger.

02

Engineer the whole product.

Connect interfaces, APIs, data, and on-chain logic into software that works as a complete product.

03

Build for the long run.

Make deliberate choices about architecture, security, and maintainability, so the product can grow without becoming harder to change.

TOOLS OF THE TRADE

TypeScript / React / Next.js / Vue / Ethereum / Solana

GOOD PEOPLE. INTERESTING IDEAS.
