Two years into freelancing, I'm on track to earn 7-8x my Amazon salary and have hired three engineers. There will be no better investment of your time, your money, and your learning bandwidth than being inside a community like this.
Data Freelancer gave me the confidence and clarity to bet on myself. I got my first client at $13K, converted my full-time role to consulting, and crossed $100K in revenue 3 months ahead of my original goal.
As the program progressed, it became clear that the freelance path suited me best for the coming years. Since joining, I've landed my first two AI freelance projects, which was a big milestone and proof that the system works.
I had no idea how to earn a living selling my skills, even after years in corporate as a principal engineer and director. The program gave me the confidence and insight I needed to land my first client.
This program has been a game changer in getting started with freelance work and changing how I think about running my practice. Since joining, I secured a contract, expanded my network of people actually building, and found a resource to consistently improve my processes.
As a full-time Data Scientist, I was exploring the transition to running my own data consulting business but felt overwhelmed with ideas. Data Freelancer helped me align my focus, accelerate my initial progress, and make the shift to entrepreneurship feel more attainable.
When I started to actually put it all into practice, I had an ROI within 4 weeks! I most definitely recommend Data Freelancer to you if you're into freelancing anything data related.
Data Freelancer gave me the structure and guidance I needed to turn my skills into a consistent freelance business. I landed my first contract worth just under five figures much sooner than expected, and within the first 6 months of freelancing I was able to quit my job.
Coming across Dave and Datalumina was one of the best investment decisions I've made. You'll learn practical ways to build inbound marketing, design AI solutions, and solve real business problems alongside a diverse group of talented professionals.
I'm three months into the program and have already landed three contracts, thanks to Dave, the Datalumina team and the community. I highly recommend this if you are serious about your freelance career. It is well worth the investment!
This is the best course I've ever enrolled in! Dave helped me become an independent freelancer. I had the desire to start freelancing but was afraid of losing a stable income. What I didn't realize was that I could earn more than in my regular job.

The math has changed
The market today doesn't reward what it used to. Layoffs hit every level, internal raises cap at single digits, and companies are restructuring their engineering teams. At the same time, AI gives a single engineer the leverage that used to take a small team.
If you can already ship real software, the highest-leverage move isn't waiting for the next promotion. It's building a second income on top of your day job. Real project work in evenings and weekends, charged at market rates and proven on your own terms. The risk profile is completely different than it was two years ago, and windows like this don't stay open.
