1. Project : Cost Optimization | Updating tech stack
a)I'm currently engaged in a project aimed at redesigning our application to enhance cost efficiency, with a target of reducing costs by 5-10% each month.
b)Additionally, I'm involved in upgrading the application to Java 17 and migrating the framework from Spring to Spring Boot. This migration includes updating Kafka versions, alongside fulfilling various business tasks.
2. Project : Legacy Application Redesign
a)In this project, I played a key role in redesigning a legacy application to enhance its performance and reduce the number of servers (pods in AWS) in production, thereby contributing to cost savings.
b)The redesign included transitioning the APIs to a Kafka-based architecture to improve system
response times and scalability.
c)Additionally, I revamped the payload structures sent to Kafka by switching from Java POJOs to JSON
serialised objects.
3. Project : Building Real Time Notifications Module
a) This project focused on developing a highly scalable and resilient system capable of delivering real- time notifications and server-to-server callbacks to merchants for specific transactions.
b) Additionally, it aimed to ensure real-time status updates for transactions, minimising the time required for transactions to reach a successful state.
c)Throughout this endeavour, I constructed this module from the ground up, utilising Kafka, Java, Spring Boot, and a web client. The module was rolled out in phases and continually optimised to meet transaction per second (TPS) requirements.
d)Presently, it successfully supports a TPS of 5k without experiencing any Kafka lag.

Project: Loan Punching Application
a)In this project, I contributed to a loan application interface utilised by agents in malls and public areas. This interface enabled users to initiate loan requests by providing necessary information without needing to physically visit a bank.
b) Our application served as a frontend to the bank's backend system. Loan applications initiated through our interface were seamlessly submitted to the bank's backend application, where they could be further processed.
c) The frontend technologies utilised included Vue.js, JSP, and JavaScript, while the backend technologies comprised Java, the Spring framework, Spring MVC, and Hibernate for database interactions.
