The problem
Portfolios are static, but hiring conversations aren't. A recruiter wants to know whether I've shipped mobile apps, a hiring manager wants a production story in STAR form, and a sourcing agent wants structured answers it can compare. A PDF CV can't do any of that.
Integrated the installer management system into Multichoice's payment process so installers are paid accurately and on time.
Centralised the customer journey and operational data, reduced manual hand-offs and set up a documented AWS foundation.
What was built
A digital version of me that holds a real interview by phone-style voice call or text, grounded only in material I curated. It changes what's on screen as it answers, logs what it can't answer so I can teach it, records and QA-scores every call, and is reachable by other AI agents over MCP and A2A.

Outcome
The twin never invents a fact about my career: when it doesn't know, it says so and I'm notified. Intent-matched navigation fires within about a second, before the first answer token. Every call is recorded, transcribed and scored so review starts with the calls that need it, and one knowledge base serves text, voice, MCP and A2A.
Over R5 million in installer payments processed within six months.
Centralised the customer journey and key operational data, reduced manual hand-offs and established a documented AWS foundation for future development.
