Experience

Log Parser Using Spring Batch

https://github.com/rakibmail22/spring-batch-log-parser/
A command line application that takes a large log file name as a parameter and parses the file while extracting necessary data to the SQL database for further analysis. I developed the application using the Spring Batch framework to handle large files and their data efficiently.

Inventory API Repository

https://github.com/rakibmail22/lr-challenge/
A project that demonstrates standard ways to write REST API using Spring Boot and Data JPA with integration tests. I built the back-end REST API to create categories with dynamic attributes, for which users can create items. Several bash scripts are produced with this project for ease of deployment with Docker.

Hyperbee Social Hub

https://github.com/rakibmail22/hyperbee
A simple, web-based social hub where users can create an account, "shout" in the shoutbox, and stalk profiles. I contributed to the project with a team during my training at a previous company. The application is built using Gradle, and a WAR file may be generated, which can be deployed to any Java servlet container.

Dynamic Advanced Search Using Elasticsearch for Lab Register

Used Elasticsearch as a back end while keeping the main source of truth in MySQL. Syncing the data between the two data sources in close to real-time was a challenge, but we overcame it with event-driven architecture and RabbitMQ as a messaging queue.
