Design pattern, Architecture pattern and Microservices Training (Batch #1)
Your Code Works. But Does Your Architecture?
Here's the uncomfortable truth most senior developers discover too late: you can write clean code for years and still hit a career ceiling at ₹20 lakhs when architects are commanding ₹35-45 lakhs.
The difference isn't just experience. It's architectural thinking.
While you're debugging implementations, architects are designing systems that scale to millions of users. While you're following patterns, they're choosing which patterns prevent technical debt. While you're coding features, they're making decisions that determine if the entire application survives the next five years.
The Market Has Already Moved
Right now, companies are restructuring their monolithic applications into microservices. Cloud adoption isn't optional anymore—it's survival. Domain-Driven Design, CQRS, Event Sourcing, and Saga patterns aren't buzzwords—they're the language of modern enterprise architecture.
But here's what's interesting: most developers never learn this vocabulary. They stay trapped in implementation mode, wondering why that promotion to architect never comes.
What's Actually Stopping You
You know design patterns exist. You've probably used Singleton and Factory. Maybe you've even implemented Repository pattern.
But do you understand why these patterns exist? When to use Composition over Inheritance? How to apply SOLID principles in real-world scenarios, not just textbook examples?
More importantly: can you architect a microservices-based system that doesn't collapse under its own complexity? Do you know how to handle distributed transactions? Implement CQRS without making a mess? Design bounded contexts that actually make sense?
If you're hesitating, you already know the answer.
This Isn't Another Tutorial
On 1st November at 8 PM IST, Shivprasad Koirala (ASP.NET MVP for 6 years, 17+ years experience, trained 3000+ developers at Accenture, Bank of America, Wipro, and dozens more) will walk you through the exact architectural thinking that separates senior developers from architects.
This isn't about memorizing patterns. It's about understanding the why behind architectural decisions.
What You'll Discover in This Introduction Session:
→ Why most developers misunderstand Design Patterns (and how to think like an architect instead)
→ The connection between Abstraction and Decoupling that changes how you approach every problem
→ How SOLID principles actually work in production code (not toy examples)
→ The real difference between Strategic DDD and Tactical DDD (and why one matters more than you think)
→ Why microservices fail (and how proper bounded contexts prevent the disaster)
→ The brutal truth about moving from Monolith to Microservices

Module 12: Moving to Production
Integrating everything in ASP.NET MVC
Deployment considerations
Microfrontend patterns
Architecture Styles Covered:
Onion Architecture (Domain-Oriented)
Clean Architecture (Use Case-Oriented)
Hexagonal Architecture (Ports & Adapters)
Who Should Attend This Introduction Session:
→ Senior developers stuck at ₹15-22 lakhs wondering why that architect role isn't happening
→ Tech leads who inherit architectural messes and don't know how to fix them
→ Anyone who's built applications that "work" but can't scale or maintain
→ Developers moving from service companies to product companies who suddenly need architectural skills
→ Engineers preparing for system design interviews at product-based companies
Who This Is NOT For:
→ Complete beginners (you need solid OOP and .NET fundamentals first)
→ Developers looking for quick shortcuts (architecture requires deep understanding)
→ Anyone expecting to "master microservices" in one session (this is an introduction; the real work comes in the full course)

What Happens Next:
This introduction session gives you the architectural thinking framework. At the end, you'll have the option to join Batch #1 of the Complete Training Program (paid course with comprehensive hands-on implementation, real-world project, lifetime access, and direct access to Shivprasad for doubt resolution).
Full transparency: This introduction session is designed to show you what's possible. The complete training is a paid program. No pressure, no hard sell—just a clear pathway if you're serious about making the jump to architect-level thinking.
Reserve Your Spot Now
Space is intentionally limited because this is live, interactive, and Shiv personally answers questions.
This isn't recorded content you can "watch later." This is your chance to ask the questions that have been blocking your architectural understanding.
The real question: Six months from now, do you want to still be coding someone else's architectural decisions, or do you want to be the one making them?
See you on November 1st.

P.S. — If you're already making ₹35+ lakhs as an architect and confidently design microservices systems using DDD, CQRS, and distributed patterns, you probably don't need this. But if you're stuck in implementation mode and frustrated watching less-technical people get architect roles because they understand systems thinking—this session will show you exactly what's missing.
