Prateek Sahni, MEng

Asking why. Building what's useful. Getting it where it's needed.

Prateek Sahni, Mechanical Engineer & AI Software Builder: I build systems,
physical & digital.

Mechanical & manufacturing engineer who now builds AI-powered software, working closely with the people who use it. Same habit throughout: understand a messy process, then engineer a better system for it.

Work together

Stuck on something? Let's think it through.

I enjoy hard problems more than finished ones. If you're building something and have hit a wall, or haven't started because you're not sure how, I'm happy to talk it through. Sometimes that turns into a project. Often a conversation is enough.

You're stuck

A second pair of eyes

A process that won't scale, a build that's stalled, a tool that doesn't fit how your team actually works. I'll help you find the real bottleneck.

Process & workflow reviews
Scale-up and quality problems
Untangling messy tools and data

You need it built

Building it with you

From a first version to something your team relies on every day, designed around the people who will use it.

SaaS products & internal tools
CRMs, automation and AI agents
Desktop and web apps

You're still deciding

Thinking it through

Which approach, which technology, build or buy, how to take it to market. An outside view from someone who has worked on all three sides.

Technical & product advisory
Manufacturing and process strategy
Sales process and go-to-market

How it usually goes

1
Tell me what you're working on
A few lines in the form is plenty. No brief or deck needed.
2
A free 30-minute call
Usually within a day or two. We work out what's actually going on and what would help.
3
An honest answer
Whether I'm the right person, someone else is, or you don't need outside help at all.
