You will get Java application bug fixing and production support
Project details
You will get reliable Java application bug fixing, maintenance, and production support focused on finding the actual cause of the problem rather than applying temporary fixes. I will review the affected code, analyze errors and application behavior, identify the root cause, and implement a tested solution. With experience in Java, Spring Boot, Angular, REST APIs, databases, AWS, and enterprise web applications, I can work with both new and existing applications. Whether you need a specific bug fixed, an existing feature maintained, a production issue investigated, or an application improved, I will focus on stable functionality, clean code, and minimal disruption to your existing system.

About Rishabh Dev
Angular & Spring Boot Developer | Java | Full Stack Web Apps
Patna, India - 12:08 pm local time
I build and improve production web applications using Java, Spring Boot, Angular, REST APIs, databases, and AWS. My strongest area is backend engineering and system design, but I’m comfortable working across the full stack when the project needs it.
I’ve worked on enterprise applications where reliability, performance, maintainability, and clean architecture matter. At Nissan Digital India, I delivered 5 successful projects with zero P0/P1 production bugs, led technical design and code quality for multiple projects, and worked on systems used by 500+ users.
𝗛𝗲𝗿𝗲’𝘀 𝘄𝗵𝗲𝗿𝗲 𝗜 𝗰𝗮𝗻 𝗵𝗲𝗹𝗽:
→ Java & Spring Boot backend development
→ Angular web application development
→ REST API development and third-party integrations
→ Full stack application development
→ System design, low-level design and architecture
→ Microservices and reusable application components
→ MongoDB, RDBMS and database design
→ AWS-based application development
→ Performance optimization and production issue resolution
→ Existing application enhancement, maintenance and modernization
𝗔 𝗳𝗲𝘄 𝗿𝗲𝘀𝘂𝗹𝘁𝘀 𝗳𝗿𝗼𝗺 𝗺𝘆 𝗿𝗲𝗰𝗲𝗻𝘁 𝘄𝗼𝗿𝗸:
→ Reduced AWS Lambda latency by 50% by addressing cold-start issues and removing unnecessary framework overhead.
→ Improved development efficiency by 30% by designing reusable Angular components for future modules.
→ Led a team of 10 developers across technical design and code reviews.
→ Built applications supporting maintenance activities for 500+ users.
→ Delivered a rapid prototype in one month and helped increase stakeholder satisfaction by 25%.
My core stack includes Java, Spring Boot, Angular, JavaScript, TypeScript, RxJS, MongoDB, RDBMS, AWS, Git, Postman and Apache JMeter.
I also have experience working with data and ML systems, including large-scale data processing and anomaly detection, so I can comfortably work on projects where backend engineering, data processing, and intelligent systems overlap.
If you have an existing Java/Spring Boot application that needs improvement, a new backend or full stack application to build, or a system that needs better architecture and performance, send me the details. I’ll first understand how the pieces fit together, then suggest the simplest practical way to move it forward.
Steps for completing your project
After purchasing the project, send requirements so Rishabh Dev can start the project.
Delivery time starts when Rishabh Dev receives requirements from you.
Rishabh Dev works on your project following the steps below.
Revisions may occur after the delivery date.
Step 1 — Issue & Code Review
I will review the reported issue, affected functionality, codebase, logs, errors, and steps to reproduce the problem.
Step 2 — Root Cause Analysis
I will trace the issue through the relevant application logic, APIs, database interactions, and dependencies to identify the root cause.
