Airmeet

I joined the technology team as one of the first full-time engineers at the start of 2020. Using React best practices, I refactored the code for maintainability and documented the core ideas and guidelines for feature development.

This elevated our product from an alpha prototype into a highly scalable, globally available application.

Using React Hooks, I split the monolithic codebase into reusable modules and helper utilities. This helped onboard new team members quickly and scale the product rapidly to meet rising market demand due to the Covid19 pandemic.

Leveraging developer tools and profiling, I introduced chunking and lazy loading to improve the load time of the product by one order of magnitude and reduce the CPU and memory footprint. These reusable utilities are still in place and allow all new development to sustain the higher scale and rapid delivery.

Leveraging my experience with Webpack and Nginx, I improved the developer experience to support a growing team and eliminate testing bottlenecks. I integrated static development builds with unique URL's into the team's daily toolchain, improving delivery and QA timelines exponentially. This reduced our time to production by more than a week.

Telemedicine Web App

https://www.getboost360.com/online-doctor/features/
A React and Twilio-based secure 1-on-1 video consultation web app for doctors to consult with patients. The app offers a recording of the consultation for reference. Integrated custom OCR and PDF generation design enable doctors to issue digitally signed online prescriptions that are valid at any pharmacy in India.

I built the end-to-end application, with hosting on Azure, and integrated the client's custom federated authentication system for a seamless experience.
The app was part of a larger ecosystem of applications offered as part of a digital transformation suite. I continued working with the client to evaluate and upgrade relevant portions of their offerings.

Kitsune IDE

https://www.getkitsune.com/
A cloud integrated development environment (IDE)for the Kitsune Serverless Language.

I joined the project as an independent consultant responsible for designing and developing enhancements to the developer experience for the Kitsune IDE. I introduced support for editor plugins using data-driven (JSON) configurations, including visualization of data models and a JSON tree viewer/editor.

I leveraged the reusability of React to modularize the codebase. I expanded the store capabilities to support a multi-tab editor layout, as well as error detection and save capabilities for the same.

Finally, I prepped the codebase for open-sourcing the IDE. This included documenting every aspect of the project, from architecture to utilities, tools, and contribution to development guidelines. I provided support for issues opened against the OSS codebase and ensured end-to-end testing and product delivery for the same.

eCommerce Rewards Platform

https://www.creditcardrewards.hsbc.co.in/
A React-based credit card rewards eCommerce platform.

I designed and implemented the front end for the eCommerce rewards application for a leading international bank currently in production use. The project involved a fully static React application deployed as a serverless website. The site sourced data from the bank's rewards partner back end and integrated SSO auth via the bank's internal API.

The application used a Redux store to manage user preferences and cache the page data. It implemented fuzzy search and flexible filters based on the incoming data schema.

The project included lazy loading page data, with infinite scrolling for a smooth user experience. It was also designed and implemented as a fully responsive website with mobile support and extra-wide screens.

The project structure was built to be reskinnable for different clients, with a pluggable color theme and logos.

Automated Crypto Liquidation Bot

https://www.silo.finance/
A Node.js-based strongly typed liquidation bot designed to react to events from The Graph blockchain service and perform on-chain actions via in-house Ethereum smart contracts. I leveraged Dependency Injection and OpenAPI documentation to ensure a consistent developer experience with a keen sense of performance. I also developed a system to process a large number of blockchain events in the background, to build a pipeline that would help researchers determine business rules for liquidation decisions in real time.
