What Makes It Different
Linear algebra, probability, and optimization form the bedrock. You understand why, not just how.
Every concept is implemented from scratch. No hiding behind libraries until you understand the internals.
We open every layer. Transformers, attention, backprop — you build them, you own them.
The Journey
Build the mathematical intuition and implement classical ML algorithms from scratch.
Master neural architectures and understand what makes modern AI systems work.
Apply cutting-edge techniques and build production-ready AI systems.
Who This Is For
Backend or full-stack developers who want ML depth beyond API calls.
Seeking first-principles understanding of the models you use daily.
Production experience but want to think like researchers.
Comfortable with Python or another programming language
High school level algebra and basic statistics
Prior ML experience — we start from fundamentals
“I had the pleasure of working with Puru at MathWorks. My peers and I always appreciated the depth with which Puru approached engineering problems as well as his philosophy towards designing solutions. He has a commendable grasp on a variety of domains like natural language processing and audio processing.”
AI Vector Search Engineer, Oracle
“I had the privilege of learning from Puru during the System Design Fellowship. He turns each learning session into an approachable conversation, bridging the gap between theory and real-world intuition. His sessions will always leave you smarter, more confident, and genuinely excited to build.”
Senior Software Engineer, Tech
“I've had the chance to interact with Puru and learn valuable insights into Machine Learning through him. He has a natural ability to simplify complex topics and explain them in a way that makes sense, no matter how technical they are.”
Enterprise Architect, Enterprise
“Puru has a way of making machine learning feel less like rocket science and more like a conversation. During my time at the LexAI Fellowship, he made topics that usually seem intimidating feel surprisingly manageable.”
Consultant, Deloitte
“His mentoring and teaching abilities are truly outstanding, especially his approach of focusing on practical, industry-applicable knowledge. He equipped me with real-world Machine Learning skills and insights needed to thrive.”
UX Researcher, MathWorks
“I've had the opportunity to learn from Puru during the Lex AI Fellowship. He breaks down complex concepts, especially the math, into simple, intuitive steps. Even the most abstract ideas feel approachable.”
Computer Engineering Student, Thapar Institute
“Working with Puru has been one of the most enriching experiences of my journey. His technical depth across system design, AI/ML, and large-scale engineering challenges is truly exceptional. He has a rare ability to simplify complex problems.”
Software Engineer, Tech
“Puru didn't just shape how I write code, he changed how I think about technology and its purpose. Watching him work is like seeing someone translate philosophy into engineering: grounded in first principles, deeply thoughtful.”
