Founder & Principal
I love solving problems with data and code. There's something satisfying about taking a messy dataset or a manual process and turning it into something clean, automated, and useful. Whether it's building forecasting models, designing ETL pipelines, or creating web applications, I'm genuinely curious about how things work and how to make them better.
I work across the full stack—data engineering, machine learning, web development, cloud infrastructure—because different problems need different tools. I'm constantly learning new technologies and approaches, not because it's trendy, but because I'm genuinely interested in what's possible and what actually works in production.
Most of my projects involve government agencies, small businesses, and organizations with specific data challenges.
I enjoy the variety—one week I'm building a Power BI dashboard, the next I'm writing Python scripts for data transformation, then deploying a Blazor web app to Azure. Then I'll dive into statistical models—sometimes experimenting with them directly in Fabric—refresh my calculus to better understand the optimizers under the hood, and connect it all back to the system as a whole. That cycle of building, learning, and connecting the pieces is what makes the work interesting, satisfying, and challenging for me.

Director of Marketing and Sales
Lida Rahbar
Lida loves the variety of what she does — one day it's campaigns and content, the next she's working through the sales process or sitting with customers to understand what's really clicking. She brings real energy to all of it.
She sees marketing and sales as two sides of the same coin. She's always testing ideas, learning what resonates, and staying focused on results that actually matter.
She's worked across a surprising mix of industries — museums included — and has genuinely enjoyed figuring out the marketing angle in each one. That kind of range gives her a perspective you don't come across often.
We're glad she's here.
