CalBQ is a lab information management system used in government-authorized calibration labs that calibrate various instruments for the industry as a workflow application. This application improves the quality of delivery and the labs' productivity. The product version 1.0 has successfully been deployed on the AWS serverless architecture since March 2020.
The web front end is designed using HTML, CSS, JQuery, and Bootstrap. The back end is based on Java and Spring, interacting with the MySQL database. The front end has dynamic calibration data entry templates based on the MySQL database's definition.

The client is a US-based company that offers the hospitality industry web products and web services (SaaS). These products and services are involved in governing events and group housing processes. They provide numerous benefits, including accessing and sharing real-time data, needing to use only one system from city to city, and reducing attrition exposure.

I worked on many projects, including Flexi Blocks, multi-payment, waitlist, quick lists, and maintenance work. The applications were built on Java/Jakarta EE platform and followed service-oriented architecture (SOA). I also led a database migration project for the client—from SQL Server to Oracle with a team of 35+ developers.

A development project for an AWS-based message delivery platform was executed for a new startup. Customer companies use the platform to message their employees about various deals and updates.

The startup will collect returns regarding the number of messages handled and donate part of these returns to various causes. The AWS Lambda functions using Node.js were developed as the back end using AWS DynamoDB.

We developed a Chrome extension that would be installed on individual machines and had the functionality to subscribe and receive broadcast messages.

The customer is a startup company in the water conservation space. I developed an Android application for their operations team to track water resources and conservation activities. The application talks to Node.js REST APIs and stores the data in the MySQL database. JWT was used to authenticate API users and the auto-renewal token as designed.

The APIs are consumed by an Android application and a web-based admin application. An algorithm was developed to measure the water depth using sound; it was quite challenging considering the ambient noise disturbances and limited mobile speaker volume. The admin web application was designed using Angular to manage the users, authorization, authentication, and reporting.

The application is deployed on AWS using S3, EC2, and RDS.

The Educational Institute is a charitable trust that works with underprivileged students from pre-primary to junior college. They wanted a website to strengthen their online presence so they could work with corporate organizations on CSR activities and secure donations. I designed a new website using HTML, CSS, Bootstrap, and React. It provides details about the charitable trust, its schools, and colleges across the state and allows students to share the junior college admission forms online with supporting documents. The website was deployed on AWS using AWS S3 for the front-end code.
