Open to freelance & contract work

Software that moves money, built end to end.

I’m Sajjad. I lead frontend for the ChainGPT ecosystem, where minting runs live across eight EVM networks. On my own time I ship whole products: the interface, the API and data pipeline behind it, and the AI doing the work in the middle.

Who / what

I take products from an empty repo to something with users on it.

Three years in, most of my work has been on systems where a bug is not a rendering glitch. It is somebody’s transaction. That shapes the order I build in: the data model, the failure paths and the state that survives a network switch get designed first, and the interface goes on top of them.

At Funavry Technologies I went from Associate to Frontend Lead in under two years, and I own frontend for the ChainGPT ecosystem. Away from that I build products by myself, which means the API, the ingestion pipeline and the schema as much as the screen: Node and Nest on the server, Postgres and Mongo underneath, and retrieval, agents and tool calling doing the work in the middle. That overlap between shipping product and shipping AI is where I want more of my time.

Four things I built, and what each one had to solve.

Every entry below says who owns the source. Where a link is missing, it is missing because the work is client-owned, not because there is nothing to show.

LIVENEXT.JSETHERS.JS8 EVM CHAINS

ChainGPT NFT Generator

Multi-chain NFT minting

Problem: ChainGPT’s model could generate artwork, but there was no path from a generated image to an asset that actually existed on a chain. Users had to leave the product to mint anywhere, and the handoff was where they dropped off.
My role: I led the frontend from an empty repository through to production. I owned the wallet layer, the network-switching logic, and the mint pipeline itself: generate, pin to IPFS, then call the contract. I designed it so a failed or rejected transaction never loses the artwork the user just paid to generate. I also built the OpenSea integration so a freshly minted piece can be listed without leaving the app.
Outcome: Minting runs live on eight EVM networks from a single flow, with wallet sessions handled through Web3Modal and Ethers.js. It has been in continuous production since launch and is the product I am still responsible for today.

LIVENEXT.JSREDUX TOOLKITWHITE-LABEL

ChainGPT Launchpad

IDO / token sale platform

Problem: A token launch is not one feature. Purchase, vesting, claiming, staking and KYC all have to agree with each other and with the contract, and getting any single one of them wrong means somebody loses money in public.
My role: I built the frontend for the full token lifecycle (purchase, claim, swap, staking and vesting) plus KYC verification and investor profiles, with Redux Toolkit holding sale state and SWR keeping on-chain reads fresh. I then generalised the platform so the same codebase can be deployed as a white-label launchpad for an external client rather than forked per customer.
Outcome: The platform runs public IDO sales end to end and has been redeployed under external client branding. Statistics dashboards and a blog system ship as part of the same surface.

LIVECHROME MV3JAVASCRIPTPRE-SIGNATURE

CryptoGuard

Transaction-screening extension

Problem: By the time MetaMask puts a signature request on screen, an ordinary swap and a wallet drain look almost identical. The information a user needs to tell them apart arrives after they have already signed, which is too late to be useful.
My role: I built a Manifest V3 Chrome extension that hooks the transaction events MetaMask emits and analyses them while the request is still open. The constraint that shaped the whole build was the MV3 service-worker lifecycle: the analysis has to complete and render inside a worker that the browser is free to kill at any moment.
Outcome: Risk ratings and security alerts appear inline at the moment of signing, inside the wallet flow rather than in a report afterwards.

LIVENEXT.JSTYPESCRIPTWALLET AUTH

ChainGPT AI Hub

Wallet-authenticated AI product

Problem: The AI product needed accounts, but a crypto audience will not create a password. Authentication had to be the wallet itself, across whichever wallet the user already had, without the session breaking every time they switched networks.
My role: I built the wallet-authenticated frontend: multi-wallet connection through Web3Modal and Ethers.js, session persistence across network switches, and the data visualisations the chat surface renders alongside its answers.
Outcome: A blockchain-integrated AI chatbot that signs users in with the wallet they already hold and keeps that session stable across chains.

Things I built on my own time, and shipped.

Client work is where I lead a team. These are the ones I designed, built and put in front of users by myself. Every link below is live.

Nova Support

AI support agent for online stores

Answers customer questions, tracks orders in plain conversation, recommends products, and escalates to a human only when it genuinely needs to. Retrieval runs over the store’s own catalogue and policies, and the whole thing installs with a single script tag.

Gulf Signal

Funding and tender desk for the GCC

Pulls 26 news sources into a single wire, filters it down to money events and Saudi government IT tenders, then scores the companies worth contacting. Built because finding who just raised and who is buying meant reading the same twenty sites every morning.

A Jira alternative across eight product modules: Scrum and Kanban boards, sprint planning, backlog, custom workflows, time tracking, reporting, and an assistant that plans against the sprint you actually have.
