What People Who've Done the Programmes Say
These are real experiences from people who've been through Cortexia cohorts. They're honest — including the bits about what's harder than expected.

"I'd tried two other online Python courses and given up both times. The Foundations programme was different because the pacing actually made sense — and having a real person look at my code and tell me specifically what I'd misunderstood made a big difference. It took effort, but I got through it."
"The ML Engineering track is not easy — which is actually what I wanted. I work in operations for a logistics company and wanted to understand the ML tools our data team uses. The projects used familiar types of data (delivery times, demand patterns) which made it easier to see why each step mattered."
"I appreciated that the mentors were direct about what the programme covers and what it doesn't. There were no claims about what I'd be able to do afterwards — just a clear description of the curriculum. The capstone project genuinely stretched me, and having Arjun's input during the 1-to-1 sessions was worth a lot."
"I did the Foundations programme while working full-time. The sessions are recorded, which saved me several times when I had to work late and couldn't attend live. The exercises took me about 8–9 hours a week in total, which I'd managed to fit around my schedule by week 3."
"The code review feedback was honest — probably more honest than I was expecting. On one submission I got told clearly that my approach worked but was harder to read than it needed to be. That kind of feedback is what I was hoping for. The programme itself moved at a pace that felt right for the level."
"I enrolled in the Advanced programme after completing the ML Engineering track here. Having the same team and a consistent teaching style across both made the transition easier than starting somewhere new. The deployment section was the most practical AI content I've come across — actually useful for what I want to build."
Learner Journeys in Detail
A closer look at how three learners approached the programmes and what they were able to do by the end.
Starting Point
Rashidah worked in HR and had no programming background. She wanted to understand what Python actually does before deciding whether to invest more time in learning it.
What She Did
Enrolled in AI Foundations. Attended all live sessions and submitted exercises weekly. Needed extra time on data handling in week 4 but used the recordings to catch up. Completed her portfolio project — a basic salary bracket prediction model — in week 8.
By the End
Could read, write, and debug Python scripts. Understood what her data team's tools were doing. Had a working model she could explain to non-technical colleagues. Duration: 8 weeks.
"I didn't need to become a data scientist. I just needed to stop feeling lost when the data team presented their work. That's exactly what happened."
Starting Point
Kelvin had been writing Python scripts for two years to automate reporting. He knew the language basics but had never built a model or worked with ML tooling.
What He Did
Joined ML Engineering. Worked through structured projects using delivery and inventory datasets similar to his company's data. Code review sessions helped him understand why his feature engineering choices weren't working as expected in weeks 6–7.
By the End
Completed two applied portfolio pieces. Could build, evaluate, and compare classification and regression models. Had a clear sense of what he'd need to learn next to move further into ML engineering. Duration: 12 weeks.
"The code reviews were genuinely useful. Not just 'this works' or 'this doesn't' but an actual explanation of what would have been a better approach and why."
Starting Point
Siti had completed ML Engineering at Cortexia and wanted to go deeper into neural networks and learn how to deploy models as something usable — not just notebook outputs.
What She Did
Enrolled in Advanced AI. Worked through deep learning architecture over the first half, then spent the latter weeks on the capstone — an image classification system with a simple API wrapper. Used her 1-to-1 sessions to work through tuning challenges and a deployment issue.
By the End
Completed a deployable AI project with documented architecture and a clean API. Understood the decisions behind the model design. Capstone formed the centrepiece of her portfolio. Duration: 16 weeks.
"The 1-to-1 sessions made a real difference during the capstone. Having someone review not just the code but the overall design choices helped me avoid a significant architectural mistake early on."
