In my own words

How I got here.

I'm Shahzaib Shoaib. I founded Zaibex and I lead every build it takes on. I've been writing software for clients since 2018, and building with large language models since GPT-3's first week. Nearly everything I ship now has a model somewhere in the middle of it, doing a job that someone used to do by hand or never had time for.

I started in 2018 at Hasati, building storefront websites, React admin panels and checkout screens. In 2019 and 2020 I took contracts on Upwork. Between 2020 and 2024 I was a senior full stack developer at Vaionex, working on digital-asset products such as NFT exchanges and crypto wallets, and mentoring the junior developers. The project from those years I point people to is Legaliser, an AI contract drafting and review platform. I was a senior engineer on its product team. My part was the contract analysis tools. For the insights tool I added a schema that makes the model fill in typed fields, so the screen gets the same shape of answer every time.

Zaibex is where I do this work directly for the people who need it. The biggest build so far is ResultPal. We built the full ResultPal platform for author Dr. Pelè. He sells it to organizations. Its AI coach helps people use his teaching, and it was in production in about three months.

I lead the technical architecture, engineering decisions, and software implementation of ResultPal, translating Dr. Pelè's proprietary methodology, product vision, and detailed functional specifications into a working SaaS platform.

Most of my work now is for coaching businesses. Some are coaching companies with a team of coaches, and some are experts who sell a method of their own. Both already have something that works in a session. What goes missing is the week after, when people go back to their inboxes. An AI practice coach built on the method gives people somewhere to keep practicing, and gives the coach a way to see whether it's sticking.

Focus

What I build now.

  • AI practice coaches for coaching businesses

    A coach built on your method and your words, that people can practice with between sessions. It checks in on the goals they set. Leaders see patterns across a group without reading anyone's chat. ResultPal works this way.

  • Voice agents

    Agents that hold a real phone conversation. For a hiring team I built one that runs first-round phone interviews, follows up with AI avatar videos and hands recruiters a shortlist with a short summary of each person. The recruiters still decide who gets hired.

  • Platforms around the AI

    When a coach or an agent needs a full product around it, I build that as well. ResultPal has five roles, and each one sees only its own part of the product.

  • AI tools for a small-business program

    For an Australian program that helps small businesses adopt AI, I've built a timed workshop exercise, an avatar that interviews people for testimonials, an event app that emails each attendee a personal AI plan, and a pipeline that turns one founder interview into eight videos.

How I work

Six things you can hold me to.

  1. 01

    I lead every build. The person on your first call is the one making the technical decisions.

  2. 02

    It starts with a free 30-minute call with me. If a build makes sense, we run a free audit and I send a one-page plan with a fixed quote in writing before any work starts.

  3. 03

    I work with several coding agents running at once, mostly Claude Code, Codex and Cursor. They make me fast. Keeping the code clean at that speed is my job, so I decide the architecture and I review what they write.

  4. 04

    Before a release I write the acceptance criteria and a scripted run through the app that checks what was saved after each step.

  5. 05

    Models get things wrong, so I plan for it. Where the output has to hold a shape, a schema checks it. Where a decision matters, like who gets a second interview, a person makes it.

  6. 06

    You own what I build, code and data included, and it runs in your own accounts. I don't take a revenue share.
