About Shadaab

Hi, I'm Shadaab — Software Engineering Lead at Optum (UnitedHealth Group), Hyderabad, with 7+ years building Java backends that run in production every day.

What I do at work — and bring into every class:
• Migrated a large healthcare-finance platform from Java 11 → 21, Spring 5 → 6 / Spring Boot 3, Hibernate 5 → 6 and JBoss 7.4 → 8.1, plus a move from AWS to Oracle Cloud
• Tuned slow SQL/Hibernate queries and rebuilt batch jobs with parallel, chunk-based processing
• Fixed critical security vulnerabilities and high-priority production bugs in claims and payment flows
• Built REST/SOAP and cross-cloud API integrations
• Review code and mentor junior developers on my team

Before Optum: Java developer at NTT DATA, Bangalore (2019–2022) on a consumer healthcare platform — HSA/FSA accounts, claims, batch jobs, reports, Spring + Hibernate + Oracle.

B.E. Computer Science, Government Engineering College, Raipur.

I teach what interviewers actually ask and what real projects actually need — not textbook theory.

About the lesson

Become a job-ready Java backend developer — with real projects and interview practice.

Who it's for
• College students and freshers learning Java from scratch
• Developers switching into Java / Spring Boot backend roles
• Working professionals preparing for interviews
• Developers who need help on a live project (job support)

Pick your track
1. Core Java — OOP, Collections, Exceptions, Java 8–21 features (Streams, Lambdas, Records), Multithreading
2. Spring Boot & Microservices — REST APIs, Spring Data JPA/Hibernate, Spring Security, exception handling, Docker
3. Interview prep — Core Java & Spring Boot questions, coding rounds, SQL, system-design basics, mock interviews with feedback, resume review
4. Job support & assignment help — debug real project issues, code review, SQL/Hibernate performance, Java/Spring upgrades

️ Projects you'll build for your resume/GitHub
• E-commerce backend (Spring Boot + JPA + MySQL)
• Microservices app with Docker
• A batch/file-processing job like the ones used in fintech companies

How classes work
• Free first class: we discuss your goal, check your level and make a plan
• Live 1:1 with screen sharing — you write the code, I guide
• 80% hands-on, 20% concepts
• Notes and code shared after every class
• WhatsApp doubt support between classes
• Taught in English, Hindi or Urdu

Book your free first class and tell me your goal — interview, project, college course or job switch.

I highly recommend Shadaab as a tutor. I have seen how dedicated, patient, and supportive he is when it comes to teaching and helping others learn.

What I appreciate most about his teaching style is his ability to explain concepts in a simple and easy-to-understand way. He is patient with questions, adapts his explanations according to the learner’s level, and makes sure the concept is clear before moving forward.
