I'm Swaraj Nayak — currently a Senior Software Engineer at TCS Bhubaneswar, with 7+ years building production Java systems at companies like Digit Insurance. JavaNoxLab is where I teach what working engineers actually need: not syntax — judgement.
Anyone can read documentation. What separates working engineers from the rest is knowing what tradeoffs to make, where things break in production, and how to debug when nothing in the textbook applies.
Every concept tied to how it's actually used in production — at companies handling millions of transactions and 15-20 Crore in monthly revenue. No toy examples.
I've led teams of 10, mentored junior devs, and conducted technical interviews. You'll learn what hiring managers actually look for in a backend engineer.
Java 8 streams, Spring Boot microservices, performance tuning, Kafka, Redis caching, system design — the stack that real engineers use every day.
Every class is live. Ask questions in real time. Code along. Get instant feedback. No watching pre-recorded videos at 2x and hoping you understood.
Mock interviews, DSA, system design walkthroughs — and the same Java 8 questions I've personally been asked at top product company interviews.
Limited seats per batch so I actually know your name, your code, and where you're stuck. You're not a row in a spreadsheet — you're a student.
Whether you're starting from zero, prepping for interviews, or trying to break into backend roles — there's a track designed for exactly that goal.
The foundation every backend engineer needs. We go deep into OOP, collections, multithreading, and Java 8+ features the way they're actually used in production code — not the way textbooks describe them.
Backend developers don't write Java in isolation — they query databases. This track ties Java tightly to SQL: JDBC, JPA/Hibernate, query optimization, and how to design schemas that scale.
The complete backend developer track. Build real REST APIs, microservices, and integrate with Kafka, Redis, and AWS — the exact stack used at companies hiring backend engineers in India today.
Every trainer at JavaNoxLab is an active industry professional — not a full-time teacher. What you learn here comes straight from production systems, real codebases, and live interviews.
Specialises in Core Java and collections deep-dives. Known for making multithreading finally click for students who've been confused for years.
Backend engineer with deep SQL and Hibernate expertise. Teaches query optimisation the way it's actually done when production is on fire at 2 AM.
Spring Boot and microservices specialist. Has built REST APIs serving millions of requests. Her capstone projects are what students put on their resumes and get hired for.
JavaNoxLab students don't just learn Java — they get hired. Through industry referrals, project portfolios, and interview coaching, we make sure your skills actually land you a job.
Our trainers work at TCS, Digit Insurance and top product companies. When you're ready, we refer you directly — skipping the resume black hole. A referral from inside the company changes everything.
You'll graduate with a real Spring Boot capstone project on GitHub — REST APIs, Microservices, Kafka, Redis. Three of our students got their first interviews purely because recruiters clicked their GitHub link.
We run mock interviews with the exact Java 8, Spring Boot, and SQL questions asked at TCS, Infosys, Wipro, Cognizant, and product startups — so you walk in prepared, not nervous.
These are people who joined when they were stuck in support roles or struggling with interviews — and came out the other side as confident backend developers.
"Awesome." Bikas sir's teaching style is so clear. I finally understood Java streams after struggling for months. Real production examples made all the difference.
"Nice." Raheem sir explains SQL and Hibernate so patiently. I was copy-pasting queries blindly before. Now I actually understand why queries are slow and how to fix them.
"Brilliant." Sangita ma'am's Spring Boot sessions are gold. She shares real bugs from production and asks us to debug them. Got promoted from QA to backend dev at my company.
"Incredible." Bikas sir made me restart from collections and streams the right way. Within 3 months I cleared Cognizant and Wipro both. The Java+SQL combo is the one.
"Wow." Raheem sir's live batch is small — he actually knows your name and your code. Every doubt gets answered in real time. Felt personal, not like a lecture at all.
"Game-changer." Sangita ma'am's capstone project is on my GitHub and resume. Three recruiters asked me about it. Got an offer from a Bangalore startup as backend engineer.
