CASE 01

Conversational operations

Conversational Booking & Dispatch

A WhatsApp-first booking and operations product shaped around how passengers, drivers and operators already coordinate in real life.

Focus: Conversational AI · Workflow design · User research · Operations · Product delivery

Pilot in preparation · Oct 2026

Problem

Taxi booking and dispatch depends on fast coordination between customers, drivers and operators across a conversational workflow.

Discovery

I interviewed working taxi drivers and tested real booking scenarios to understand how booking, driver matching and operator intervention work in practice.

Product decision

Design around an existing user behaviour: conversational booking through WhatsApp, connected to a structured workflow for qualification, matching, dispatch and human intervention.

Validation

The conversational flow is being tested against real booking scenarios ahead of pilot.

Key decisions

  • Meet users in an existing communication habit
  • Connect customer conversations to operations
  • Keep an explicit route for human escalation

CASE 02

AI-assisted tender review

ElecCount

An AI-assisted product for reviewing electrical tender take-offs, designed around the way estimators work and the evidence they need to verify each result.

Focus: AI-enabled product experience · Domain discovery · Human-in-the-loop design · QA · Decision support

In development · testing on live tenders

Problem

Electrical tender take-off review is detailed work where assistance is valuable, but unreviewed automation would create the wrong kind of risk.

What I observed

The product needs to support professional judgement rather than pretend it can replace it.

Product approach

Use AI to assist the review workflow while preserving a clear human validation step before work is accepted.

WORKFLOW / 02 Current product direction
01Tender input
02AI-assisted review
03Human validation
04Reviewed take-off

Key decisions

  • Human-in-the-loop by design
  • Test against live tender work
  • Treat AI output as assistance, not ground truth

CASE 03

Consumer · investment · Web3

Digital Customer Journeys in Regulated Products

Product delivery across customer onboarding and identity journeys in regulated consumer, investment and Web3 products.

Focus: Customer journeys · Identity & KYC · Requirements · Integrations · UAT & launch

Selected product experience

Problem

Regulated journeys need to remain clear and usable while meeting business, identity and compliance requirements.

What I observed

Good delivery depends on turning policy and business needs into journeys, acceptance criteria and testable product behaviour.

Product approach

Translate complex requirements into customer journeys, edge cases and testable product behaviour, then work across design, engineering, business and external partners through delivery, UAT and launch.

How I work

I start with the problem rather than the feature.

I start by understanding the user, the context and where the current journey breaks down. I turn those insights into clear product decisions and requirements, then work closely with design, engineering, business stakeholders and external partners through build, integration, testing and launch.

In my recent independent product work, I also use AI-assisted development to move more quickly from product thinking to implementation and real-world validation.
