About me

I spent years as a consultant telling stories with data...

...now, I engineer the
systems that make those
stories possible

How I work. To me, a project isn’t finished just because the code runs. It’s finished when it solves the problem. I love owning the whole journey. From architecting the backend to pitching the final demo in the boardroom, I bridge the gap between the terminal and the stakeholders to ensure the tech doesn’t just run, but actually lands with the users.

The Proven Architect

Turning messy data swamps into trusted, single-source-of-truth systems. I don’t just build pipelines; I build assets. Leveraging my AWS Certified expertise, I architect secure, government-grade environments that balance performance with cost-efficiency.

The Award-Winning Storyteller

Awards don’t matter, but clarity does. As a Young ESOMAR Award winning, I specialize in transforming millions of rows (like my dashboard tracking 150k+ personnel) into intuitive visual narratives that the boardroom can actually use to make decisions.

The Practical Tinkerer

I build AI that earns its keep. From deploying Text-to-SQL engines that democratize data access, to engineering predictive models that achieve 1-2% MAPE, I focus on practical automation that reduces manual toil and accelerates business workflows.
