Senior Data & ML Platform Engineer | dutchengineer.substack.com | Host of Ask A Data Mentor Podcast

Built real-time ML systems delivering millions of daily inferences. Integrated LLMs that saved over 1,000 hours per week across the company. Designed scalable MLOps platforms that took model deployment from months to days.

I have spent the last 8+ years driving AI and ML engineering efforts across startups and high-growth companies. My work spans productionizing models, leading company-wide ML initiatives, and building systems that work. 

Highlights:
Led LLM integration at Equipmentshare, embedding OpenAI into internal tooling to save 1,080+ hours weekly
Deployed Zwift’s real-time racing score model, handling 8.6 million inferences per day
Cut ML deployment times from months to 3 days with standardized CI/CD and packaging
Rolled out Databricks company-wide, reducing deployment cycles by 4x
Built ML pipelines for pricing $3B+ in fleet assets, churn risk, and invoice automation

I write often on machine learning systems and infrastructure on dutchengineer.substack.com, and I enjoy helping teams ship fast, reliable ML in production.

We built "data mode" for all the top LLMs 💯 

If you go into ChatGPT and ask it to a "connect to snowflake and build customer churn visualizations for our telecom customers," it will fail. 

Mito AI let's you use any LLM (GPT, Claude, Gemini etc.) and gives it the tools to complete 𝐚𝐜𝐜𝐮𝐫𝐚𝐭𝐞, 𝐭𝐞𝐬𝐭𝐚𝐛𝐥𝐞, 𝐚𝐧𝐝 𝐚𝐮𝐭𝐨𝐦𝐚𝐭𝐞𝐝 𝐝𝐚𝐭𝐚 𝐭𝐚𝐬𝐤𝐬. 

Out of the box, it can:

1️⃣ Connect to any database or gather data from the internet 
2️⃣ Build Python scripts and visualizations 
3️⃣ Turn your analysis into a shareable, self-hosted app

This means colleauges can access your analysis without needing to download any software. 

We're not building our own LLM for data -- we're supercharging all the great work that leading AI researchers are already doing.

Founder of Mito AI (YC) | Build anything from your data

If I want to merge two PDFs, why do I have to go to a website that looks like it is selling my data to North Korea?

Someone (possibly me, tomorrow) needs to build a unified tool for the long tail of random work tasks. 

- Merging PDFs
- Convert video to GIF
- Adding my signature to any form of document 
- Strip audio from video 
- Convert PDF to Word 
- Download video or audio from youtube, X, instagram etc. 

AI is surprisingly bad at a lot of this. 

I wouldn't pay for a tool that does just one of these, but I'd pay a lot for one that does them all.

🚨 Finally an agent that converts your legacy Excel processes to Python

There's a lot of hype around LLMs building Excel models. 

OpenAI famously released a (now deleted) GPT 5.2 demo, where it built a financial model that valued a midsize company at 1 trillion dollars (my numbers may be a bit off).

While these tools make for some cool demo videos, they miss where the real enterprise value is:

🚀 Converting legacy Excel models to Python

We've helped some of the largest banks in the world convert their burdensome, slow to load Excel models into automated Python scripts. 

Now we've released an agent that does this for you. 

in Mito AI you can upload your excel model, and it will return a Python notebook that completes the same process. 

#AI #Excel #Python #Data #Exceltopython #automation #finance

🚨Convert any blog post or research paper to a Python notebook 

Someone on HackerNews wrote a deep analysis of why they think Nvidia's stock price will crash. 

I don't speculate, but in 90 seconds Mito AI returned a full recreation of the methods in Python, including the visuals. 

Researchers, financial analysts etc. love this because they can bring new ideas into their IDE in seconds, with reproducible Python code ready to go.

⌛ This was 8 years ago, and if you try Python in Excel it feels like a feature they are still "considering."

The real way to integrate Python and Excel is to move your Excel work to Python environments -- NOT jam python functions into your workbook. 

Python environments can handle larger datasets, faster processing, and more sophisticated AI. 

This is what we are building at Mito AI. 

The Excel-user front end for Python/AI workflows 🚀

1️⃣ It's cool that Microsoft is responding to it's largest meme account

2️⃣ They should have said =IF(works = true, it works, use Mito AI)

#Excel #AI #Python #Spreadsheets

🚀 Building a cash flow model in Python: Mito AI versus Claude 

Mito AI (Left): Documented notebook with visualizations and scenarios analysis

Claude (Right): Oddly formatted documentation and cells that error

I love Claude, and use it every day (and we use Claude inside Mito!)

But when it comes to data science tasks, Mito AI gives Claude, Gemini, and ChatGPT the extra strength to be production ready 😊 

#AI #Python #Claude #Gemini #ChatGPT

💸 Overtime we've helped some of the world's largest Hedge Funds, PE firms, and Banks make the transition to Python. 

Mito AI now let's anyone become a Python first financial analyst. 

Below you can see how Mito AI let's you automate stock screening in a minute, using Python. 

Just describe your method, and Mito AI builds the automated process for you.

🚨 Mito AI is the best AI solution for make Python visualizations 

There's three ways you can generate charts:

1️⃣ Prompt it
2️⃣ Upload an image and Mito AI will generate code that recreates it
3️⃣ Use the new Chart Wizard to edit any chart in real time 

The most efficient environment for AI based data analysis is a combination of prompts and visual edits. Humans and AI working together.

The all time most upvoted post on r/Python. Someone created an open source Python workflow to download Alexa voice recordings and then got this email. 

This is a key example of the power open source development, and a beautiful story 💛 💙 


#python #opensource #development #datascience #reddit

I wrote out a whole post about why this meme going around doesn't make sense and OpenAI should not be focused on profits for a long time. 

But critiquing memes on LinkedIn is a place I'm not willing to go yet.

This is exactly the same way Claude encourages me when I have a disagreement with my cofounder (my brother).
