I have built this FREE Spring Boot Handbook to learn all Spring Boot concepts in one place. Check it out now on my website: 🔗 codingshuttle.com/spring-boo…

Recently, while studying the second module of the Spring Boot Cohort by Coding Shuttle, I came across a topic called ModelMapper. At first, I assumed it was just another utility library. However, after understanding its purpose, I realized how much repetitive code it can eliminate in a Spring Boot application. In real-world applications, sending entity objects directly to clients is not considered a good practice because entities may contain sensitive information that should not be exposed. That's where DTOs (Data Transfer Objects) come into play. DTOs allow us to send only the required data to the client while keeping internal details secure. The challenge, however, is that converting entities to DTOs and DTOs back to entities often requires writing a lot of boilerplate mapping code. This is where ModelMapper becomes extremely useful. It automatically maps fields between objects, making conversions much cleaner and reducing manual effort. Some common use cases include: ✅ Entity → DTO for API responses ✅ DTO → Entity for create and update operations ✅ Mapping collections such as List<Entity> → List<DTO> Additionally, ModelMapper can be used alongside Optional for safer null handling and ResponseEntity for better API response management. Learning small tools like these reminds me that writing less code often leads to cleaner and more maintainable applications. #SpringBoot #Java #BackendDevelopment #CodingShuttle #ModelMapper #SoftwareDevelopment

Really loved the comprehensive, step-by-step articles. Feeling confident after completing the full handbook. Huge thanks to "Coding Shuttle" & @sudoanuj sir for such a valuable resource! 🙌🚀 Link: codingshuttle.com/spring-boo…

Great initiative. Indeed, the best way to master a concept is to teach it to others. Keep going 🔥

If you know Java but haven't built real world backend systems yet, then Cohort 4.0 is for you 🫵 5 days left to join Spring Boot Cohort 4.0 🚨 #java #springboot #cohort4

Created a GitHub video to promote open source contributions over 4 years ago, it has received over a Million views and the Repo has around a thousand pull requests. Relax, it was just a dummy repo I created 😂😂 Definitely not ExpressJS, smh

Just watched @sudoanuj video “What Every Entry-Level Software Engineer Should Know Right Now” — and it hit hard. 💡 As a fresher searching for a job, I realized a job doesn’t define your worth — skills, consistency, and mindset do.

🌙💻 Late-night grind with Anuj Bhaiya! (@sudoanuj) Deep diving into the system design of Lovable – from API gateways to LLM orchestration.

This guy is gem 💎 @sudoanuj

Day 15 of Hustle 🚀 #100DaysOfCode 1.Installed & connected Spring Boot with IntelliJ (via Spring.io website). ✅ 2.Just brush up with some basic arrays and two pointer pattern questions Thanks to @sudoanuj sir — your Spring Boot videos are super helpful!

📌 Another day in my Backend Journey 🚀 🎥 Completed API videos (thanks @sudoanuj ) ✨ What I learnt: 🔹 APIs in Spring Boot (GET, POST, PUT, PATCH, DELETE) 🔹 How mappings work in Java 🔹 DB with PostgreSQL DBeaver 🔹 Postman 📨 🔹 Validations in Java #SpringBoot #Java

What an in-depth session on spring security @sudoanuj 🙉🔐….already used before, but never understood the internals this clearly — thanks @sudoanuj #springboot #javaDev #Security

Day 22 #100DaysOfCode ✅ Learned Quick Sort ✅ Implement Quick Sort in code Learn from @sudoanuj #DSA #CodingJourney #learninpublic #100DaysOfCode #CodingChallenge

Weekend backend grind 😎 Picked up something cool with #SpringBoot Thanks @sudoanuj for detailed breakdown🙌 #backendDev #java #weekend

Any company with > 60 days notice period is a red flag. Period.

I’ve realized that great developers aren’t the smartest—they’re the most persistent. So don't give up, everyone starts as a beginner and everyone faces errors. You will do great one day.

I once spent an entire month learning Kubernetes. This was back in 2021. 4 years later, still learning new stuff in k8s. #Kubernetes

What you do after 9 PM will shape your long-term career in the true sense.

I’ve failed more times than I can count. But every failure taught me something I needed to learn. Keep hustling.

Frontend devs: ‘It’s the backend.’ Backend devs: ‘It’s the frontend.’ Reality: It’s DNS.
