...bootcamp in Bangalore starting the first week of February and I need a seasoned instructor to lead it. The heart of the course is Core Java and Advanced Java, yet I also expect you to weave in data structures, advanced algorithms and regular competitive-coding drills so participants are battle-ready for contests. Beyond the core focus, you should be comfortable touching on Spring / Spring Boot, Hibernate, REST APIs and, time permitting, a quick primer on HTML, CSS, JavaScript or even Angular/React for well-rounded context. Eight-plus years of hands-on experience is ideal—though if you can demonstrate comparable depth and classroom presence, I’m flexible. Here’s what success looks like: • A day-by-day syllabus delivered before kickoff, including problem-s...

...sessions backed by Redis; the code must gracefully fall back to the current JDBC session store when Redis is unavailable. • Any additional backend clean-ups you spot during the work (for instance, refactoring the search service or tightening entity validation) are welcome, provided they are scoped and discussed first. You will be working with a Maven-built project that currently uses Spring and Hibernate/JPA with Postgresql. The code compiles and deploys, but the new modules are completely missing. I will give you access to the Git repository. Acceptance will be based on: 1. New user flows exercised through REST and verified by automated tests. 2. Sessions persisting correctly in Redis, visible via the CLI, and surviving application restarts. 3. JUnit tests must be ...

...smoothly on a standard servlet container (Tomcat/Jetty). PayPal is the only payment gateway I intend to support, so you will need to wire the PayPal REST or Java SDK into the checkout sequence, handle sandbox testing, and surface clear success / failure responses to the customer. Because speed to market matters, I would prefer you build on a framework you already know well—Spring Boot with JPA/Hibernate, Jakarta EE, or a similar production-ready stack. Responsive HTML/CSS and a touch of JavaScript (React, Vue, or plain JSP/Thymeleaf—your choice) are fine so long as the final bundle remains straightforward to deploy. Deliverables: • Source code in a public or private Git repo • SQL scripts or migration files for the initial schema • A README that d...

...Spring Boot, Spring MVC, Spring Security, and Hibernate. Once the offer is in hand, the real partnership begins. For at least six months (and possibly longer), I’ll rely on you for hands-on project guidance: pair-programming sessions, code reviews, design advice, and quick unblock support when production issues crop up. I work primarily with IntelliJ, Maven, Git, and JUnit, so familiarity with those tools is expected. Availability in IST evenings or weekends is ideal, since that’s when I’ll need most real-time help. Deliverables you’ll provide: • Attend and clear the technical interview on my behalf • Train me on project codebase and best practices for Core Java, multithreading, exception handling, Spring Boot/MVC/Security, and Hiber...

A partially built micro-service still needs a set of REST APIs finished. The codebase already runs on Spring Boot, so the work focuses on extending it with three concrete capabilities: • User authentication and authorization – Spring Security (JWT) is preferred so tokens can be issued and validated across services. • Data retrieval and storage – CRUD endpoints must persist through JPA/Hibernate to the existing MySQL instance (schema and credentials will be provided). • Third-party service integration – one external REST service (simple JSON over HTTPS) has to be consumed and its response mapped into our own domain model. Deliverables expected: 1. Clean, commented Java code inside a Maven/Gradle module that compiles and starts with the res...

...development phase. The core of the service is written in robust Core Java, with Spring Framework (largely Spring Boot) orchestrating each microservice and Hibernate handling ORM. Your role is to take ownership of individual services: designing the endpoints, wiring Spring components, integrating the Hibernate entities, and then pushing clean, tested code into our Git repo. We hold short onsite sync-ups once or twice a week, so being locally available is essential, but you’ll otherwise work remotely on your own schedule. If you’re comfortable slicing a user story into small, testable tasks, writing clean Java 17 code, and troubleshooting Spring/Hibernate quirks without drama, we should talk. Deliverables will be accepted when: • Each assigned mic...

...fully working modules: Student Management, Faculty Management and Course Management. Inside Student Management I only need the Student Profiles feature right now, but it has to be complete. Each profile must store and display Contact Information, Academic Records and a log of Extracurricular Activities. Tech expectations Please stay within the Java ecosystem—feel free to leverage Spring Boot, Hibernate/JPA, Maven or Gradle if they speed up development, and keep the codebase layered and testable. A lightweight front end is fine; a simple JSP/Thymeleaf setup or a small React view fed by REST endpoints will work as long as it is documented. Deliverables • Source code in a private Git repository • SQL schema or migration scripts • Brief setup guide (rea...

...stack: you’ll shape Spring-based APIs, fine-tune Hibernate mappings, write or refactor Java Servlets, and then jump to the UI layer to deliver features in Angular and, when needed, React. Solid database sense is equally important—you should be comfortable designing schemas, writing migrations, and keeping data models in sync with the code. We’ll collaborate through Git, pull requests, and quick stand-ups over Zoom or Slack. Each Monday I’ll share a short, prioritized backlog; by Friday I expect clean, tested code ready to merge. Clear communication and the confidence to suggest improvements are essential—this isn’t a junior mentoring gig but a peer partnership. Deliverables each sprint • Production-ready backend code (Spring Framework,...

I’m building a new web application and need a seasoned Java developer who is comfortable owning the full stack. The back-end is planned in Java—Spring Boot for the API layer and JPA/Hibernate for persistence—while the front-end will rely on a modern JavaScript framework (React is my preference, though I’m open to Angular or Vue if you can justify the choice). The work spans architecture decisions, coding, unit tests, and deployment to a cloud environment. I already have the core feature set drafted; what’s missing is the hands-on expertise to turn those requirements into a production-ready product with clean, maintainable code on both sides of the stack.

My production system still runs on Java 1.5 inside WebLogic 10.0.0. I now need the entire application lifted to Java 1.8 and deployed on WildFly 26.1. Key points you should know before jumping in: • The codebase relies on Hibernate (an older 3-series release). I want to replace that dependency with a modern, fully-supported version—or an alternative you recommend that plays nicely with Java 1.8 and WildFly’s built-in JPA provider. • I am replacing, not merely upgrading, any other outdated libraries you uncover during the migration. Feel free to suggest the cleanest stack that keeps future upgrades painless. • I don’t have pinned version numbers; I’m looking for your recommendations on stable, long-term-support releases that align with ...

I want to build a Java-based web application that handles room reservations from end to end. Users must be able to create an account, sign in securely, view available rooms, book them, and later manage or cancel their own bookings. That user-authentication piece is essential, but the rest of the stack is flexible: Spring Boot with Hibernate works for me, yet I am open to any modern Java web framework you are comfortable with as long as the code is clean, documented, and easy to extend. The app should follow a straightforward MVC or REST architecture, store data in a relational database, and run locally through Maven or Gradle before being deployed on a standard Linux server (Tomcat or Jetty are fine). A responsive front-end—whether Thymeleaf, React, or vanilla HTML/CSS—...

I regularly pick up new Jira stories that call for end-to-end feature development across our microservice ecosystem. The stack is pure Java—Spring Boot, RESTful APIs, Kafka messaging, Hibernate, and plenty of SQL—so I need a senior-level developer who can slot in whenever a ticket lands and take it from acceptance criteria to merged pull request. Typical tickets include building or extending backend services, wiring APIs and third-party integrations, and shaping the database layer. You’d push code through Git, keep activity transparent in Jira, and be available for quick huddles during Indian Standard Time hours.
