Where Junior Engineers Learn Senior-Level Thinking

You're here because building software that actually solves problems feels overwhelming

We get it. You're a junior engineer who can code, but when it comes to designing systems that solve real business problems, the gap feels impossible to bridge. Here's what they don't tell you: The best software engineers aren't just fast coders: they're strategic problem solvers.

What our members achieve:

✅ Strategic Problem-Solving - Approach any technical challenge by asking the right questions first, ensuring you build the right solution, not just any solution

✅ Senior Engineer Mindset - Think beyond code to consider maintainability, scalability, and business impact from day one

✅ Technology-Agnostic Design - Make architectural decisions based on requirements, then choose the right technology for the job

✅ Future-Proof Architecture - Design systems that adapt gracefully to changing requirements and business needs

✅ Cross-Functional Communication - Explain technical decisions clearly to non-technical stakeholders, managers, and business teams

Your journey to senior-level thinking starts here:

📚 System Design-Focused Courses

Our foundation course: LSD 101: Intro to System Design Theory - Learn the framework that makes any business problem manageable through software

LSD 201: System Design Fundamentals - Build the systematic thinking approach that separates junior from senior engineers

LSD 210-212: Real-World Case Studies - Learn to architect solutions for complex business problems:

• Content platforms (YouTube, Instagram)
• Communication systems (Slack, WhatsApp)
• Transactional systems (Uber, Airbnb)
• AI-powered applications (Coming July 2025)

New courses added every month based on emerging industry challenges!

🎯 Weekly Live System Design Practice

• Weekly opportunities to learn and design real systems using the 7-block framework
• Tackle real business problems with other growing engineers
• Present your architectural solutions and get constructive feedback
• Learn multiple approaches to the same challenge
• Build the communication skills that make you invaluable to any team

💬 Daily Problem-Solving Support

• Ask questions about system design challenges you're facing
• Share architectural decisions for community feedback
• Learn from others solving similar problems
• Get guidance from engineers who've mastered this thinking

Why Learn System Design transforms junior engineers:

1. We focus on what companies actually need

Companies don't just need people who can write code—they need engineers who can solve problems strategically. Our approach builds the systematic thinking that makes you invaluable.

2. Learn alongside peers at your level

Unlike resources aimed at senior engineers, everyone here is growing together. You'll learn faster when you're not intimidated by decades of experience.

3. Structured learning path to senior thinking

No more piecing together random tutorials. Follow our proven progression from basic problem decomposition to complex system architecture.

4. Created by someone who develops engineers

I've taught system design at UC Berkeley for years and have 20 years of experience turning junior engineers into strategic problem solvers.

Who am I?

My name is Kay Ashaolu [LinkedIn] [University Profile] and I am the host of this community. I am an Engineering Manager, a University Lecturer, and a former Staff Software Engineer. I have built systems end to end, managed teams that built systems end to end, and taught students to build systems end to end for 20 years.

My lifelong passion is to see junior engineers grow into the strategic problem solvers that the world needs today, as technology touches every aspect of our lives in bigger ways as time goes on.

What our members say:

"Kay has that rare gift of not only demonstrating deep expertise in his field, but also being able to communicate his insights in a way that is understandable to wide audiences." - Former colleague

"Professor Kay's approach [...] is very unique. He has this incredible ability to make any complex technical challenge seem very simple." — Former student

"Kay is deeply committed to creating an inclusive, supportive learning environment. His approachability and genuine care make him an invaluable resource, especially for those aspiring to advance in software engineering." — Former student

Don't let limited problem-solving skills hold back your career

The job market is tough for junior engineers right now. The engineers who stand out aren't just the fastest coders: they're the ones who can think strategically about problems and communicate solutions clearly.

Every day you wait is another day you could be developing the senior-level thinking that separates exceptional engineers from the rest.
