Projects:

1. KOREWIRELESS (eSIM provider in the U.S.): Network traffic monitoring system.

• An intelligent network monitoring solution that provides diagnostic and troubleshooting capabilities at the traffic level, so that there is greater network visibility.
• The application also allows users to set automated actions for rule violations. It also helps to manage devices under a particular company and perform actions at the network level, such as traffic blocking.
• We do have a microservice-based application, and Kafka is used for communication between applications.

Project outcome: Protect devices and transmitted data from anomalies, threats, excessive data use, misconfigured firmware, stolen SIMs, and network failures

Tech stacks: Java, Java 8, Spring Boot, Docker, Kubernetes, CI/CD, Kafka, MySQL, Git, Agile, Maven, Angular, Redis, Elasticsearch.

2. MASSIVE IoT

• Developed and implemented a solution for seamless switching from the initial bootstrap eSIM profile to a local operator profile. Leveraged GSMA Consumer SIM architecture and operator DP-a server to automate profile downloads, eliminating the need for user interaction, ensuring efficient local SIM provisioning

Project outcome: Seamless switching between the initial bootstrap profiles and local MNO profiles.

Tech stacks: Java, Spring Boot, Docker, Kubernetes, CI/CD, Kafka, MySQL, Git, Agile, Maven, Angular.

2. Connective Device Analytics (CDA):

• Worked on a session management system utilizing the RADIUS (Remote Authentication Dial-In User Service) protocol to collect and process authentication, authorization, and accounting data.
• Developed functionality to track and compute user session history, including session duration and status. Implemented real-time monitoring of active sessions, providing administrators with insights into current session statuses.
• Project outcome: Computes session details.

Tech stacks: Java, Java 8, Spring Boot, Docker, Kubernetes, CI/CD, Kafka, MySQL, Git, Agile, Maven, Angular

#dltledgers is a blockchain-based, multi-enterprise supply chain business network platform deployed in enterprises and banks such as Mondelez, Tata Motors, ANZ Bank, Shiseido, OCP, and Stockland. It helps corporations and banks build on a connected supply chain, enabling them to automate multi-party transactions, streamline processes, and reduce costs.

1. TRADER PLATFORM:

• A blockchain-based platform that helps in trade digitization, which helps to reduce delays in cross-border supply chain transactions.
• The users, based on their roles, are able to create smart contracts in blockchain, corresponding to a trade, and digitally approve the documents involved in a cross-border trade, which then stores the transaction information of these documents in the blockchain.

Project outcome: Eliminate manual processes, and help in multi-channel communication, which enhanced transparency and traceability.

Tech stacks: Java 8, Spring Boot, Git, SQL, MongoDB, Node.js, Maven, Angular, Docker.

2. TRADE DOCUMENT VALIDATION:

• This was an MVP that was developed for Singapore-based banks. Banks provide loans based on various documents involved in trade. I developed proof of concepts to avoid a situation where a trader uses the same document to get loans from multiple banks, and this was the primary objective of this project.
• The Monetary Authority of Singapore (MAS) acts as a nodal repository, creates a blockchain network with other banks, and when a trade document is financed, it will be uploaded to the blockchain network.
• This will, in turn, create an immutable ledger for that trade, and duplicate financing requests can be found by searching in the blockchain.

Project Outcome: This helps banks avoid duplicate financing.

Tech Stacks: Java, Spring Boot, SQL, Angular, Maven, Git, Node.js.

1. AVNET:

• The Avnet e-commerce application, which is used globally, provides a platform for selling electronic products to customers, and the application also provides deep engineering and supply chain expertise.
• I primarily worked as a junior Java developer, and my responsibilities were implementing new functionalities, bug fixing, and enhancements in the existing application.
• HCL WebSphere Commerce was used for application development, and Spring Boot was used to develop a few microservices.
• We had a waterfall-based project execution.
• We used Git for version control, and Jenkins for deployment activities.

Project Outcome: The application was delivered with new features for a better user experience.

Tech stacks: Java 8, Spring Boot, HCL WCS, SQL, Maven, Angular, Node JS, Git, Jenkins.

• Collection and analysis of requirements and documentation in collaboration with the IT Department, KMRL.
• Pitched in and developed a hybrid Ionic-based application using Angular that was built for both iOS and Android.
• Developed back-end using Java and MySQL.

• Company Overview: Zupp is a state-of-the-art Android application designed to promote carpooling in India.
• Being an intern, my main focus was to test the different use cases of the application.
• The main achievement I had in this project was working closely with the senior stakeholders of the company.
• Tech stack: Android.
