01 / My approach

Start with the problem.Then choose the tools.

I build document-aware AI applications, data pipelines and connected workflows - and take them past the prototype.
01

Problem first

Who needs the system, which data it can use, and what a useful result looks like - before any tool is chosen.

02

Software, not notebooks

A background in full-stack web and mobile development means AI work ends as an application people can use and maintain.

03

Reviewable steps

Architecture, prototypes and releases arrive in small pieces you can test, question and steer.

02 / Career journey

03 / Education

Academic foundation,applied at work.

Formal study in data science and AI alongside professional engineering work.

04 / How I work

Clarity at every step.

Four stages, each ending in something you can see, test and decide on.
01

Understand

Define the users, constraints, available data and acceptance criteria before choosing a tool.

02

Make it tangible

Build a focused prototype so the difficult assumptions get tested early.

03

Build & evaluate

Develop in iterations, review behaviour on real inputs and document the trade-offs.

04

Launch & hand over

Prepare deployment, monitoring and operating notes so the system can be supported.

05 / Principles

What I optimise for.

Five trade-offs I make on purpose. Hover or focus a card for the reasoning.

Useful>impressive

A small system people rely on beats a demo that only works on stage.

Simple>over-engineered

Start with the least machinery that solves the problem; add complexity when it pays.

Observable>mysterious

Logs, traces and evaluations make it possible to trust - and fix - what the system does.

Production>prototype

Deployment, monitoring and handover are part of the work, not an afterthought.

Human oversight>blind automation

People approve what is costly or irreversible; automation handles the rest.
