Web App to Process Insurance PA Requests

A web app used for processing prior insurance authorizations by pharmacies.

I worked on this project as a full-stack developer. I wrote the back end in Kotlin using the Micronaut framework and the front end in TypeScript using React. I also worked on integrating this app with third-party APIs and handled critical features like CSV report generation, dashboard, and email notifications.

I used Liquibase for database versioning and migration. I wrote PL/pgSQL procedures for materialised views and triggers and performed SQL query optimisation.

Public APIs Offered by a Digital Pharmacy

Public APIs for the healthcare ecosystem to integrate with a digital pharmacy. It was essentially a wrapper over our existing internal APIs.

I led the six-people engineering team for this project. My primary responsibilities were designing the microservices architecture with database schemas. I also worked on making the APIs secure and performant.

I also wrote the API documentation using OpenAPI Specification and Redoc.

Investors Social Network

A mobile app for social interaction between investors and stock traders, allowing for better insights.

I worked primarily as a back-end and DevOps engineer. I created the microservices architecture from scratch and worked on critical features like the daily stock portfolio refresh and leaderboard. I also developed CI pipelines for services, designed a VPC strategy for the product, and implemented it using Terraform.

I also introduced the use of AWS RDS for the relational database use-cases and configured and tuned the RDS using Terraform.

A Mobile App to View Film Events

A hybrid mobile app that can stream film events.

I helped in the development of the mobile app. Used Flutter and WebSockets to create a simple in-app chat box. I also built UI screens to view streaming videos and join zoom meetings.

Option Chaining Analysis App

The objective was to develop a React app to display the option of chaining data according to selected parameters. The data was coming on a web socket from a stock broker.

I was the only engineer working on this. I created the whole full-stack app from scratch, including building the required AWS infrastructure. I used AWS Lambda and API GW for the back-end APIs. PostgreSQL was used as a database hosted using AWS RDS.

The back end was written in Node.js, where APIs were created to fetch option-chaining data according to selected query options. A Node.js script was written to read the data on the socket and store it in a CSV file. The front end was created using React and JavaScript.

Music NFT Creation and Collaboration Platform

https://www.ommuse.com/
A React-based app to create music collaboratively and create the NFT for the created music. The app had three offerings:

1. A marketplace to explore and interact with music NFTs created by different artists.
2. A way to mint an NFT and share the earnings amongst collaborators.
3. A digital audio workstation (DAW) to create music on the web.

I worked on all three offerings. I used React TypeScript to develop this app. web3.js library was used to interact with the ethernet. The DAW was created using the Tone.js library. DAW had a lot of UI-heavy components as it was used to create music from different instruments.

I also created APIs using Express.js to integrate Stripe within the app for payment subscriptions.

Cadastral Mapping Application

https://www.grip.co.nz/
Next.js-based cadastral mapping application.

I developed the whole application from scratch using Next.js, TypeScript, and Tailwind CSS for the front end and Express.js and TypeScript for the back end. I also wrote the entire AWS and Vercel infrastructure using Terraform and used PostgreSQL as a database. I also created a few private npm packages.

Lily | AI-assisted Food Ordering App

An AI-assisted food ordering app that analyzes your food habits and health goals and suggests the best nearby restaurants and meals. The app uses OpenAI APIs for this. The app also uses MealMe APIs for restaurant and meal searches. This was a mobile app for iOS and Android built using React Native. Firebase was used as a cloud provider.

I was the only engineer working on this project. I worked on all the above-mentioned aspects of this app.
