Experience
Content Management System for Honest and Honest Beauty.com
I was the tech-lead for the launch of Honest Beauty, a new brand within The Honest Company. I led the ideation and did the admin (AngularJS) and back-end development (Ruby on Rails, MySQL, Memcached) for a novel but simple API-based content management system. It allowed setting up pages like homepage, product pages, custom pages, and more, using a drag and drop UI. The front-end of the website and mobile apps would consume the API output of the CMS to render the pages. The system allowed updating pages on the fly without going through deploy cycles, especially on mobile apps.
I worked with the design and UX team to come up with requirements and a framework that they could design on, making sure that the system would be able to support them. I also worked with the product team to define the requirements clearly.
We launched the project successfully, on time, and the architecture was adopted by the main honest.com website soon after, a project that I led as well.

Scalable Architecture for The Honest Company
I led the re-architecture of the subscription platform at The Honest Company, which allowed us to scale up to 1 million visitors a day. I also led a team of eight developers to make the Honest website mobile-friendly and implement the scalable architecture to support a $300 million annual revenue site. Technologies used were Ruby on Rails, AngularJS, and JavaScript.
Customized Shopify Checkout
I implemented a customized checkout for supporting the subscription commerce for Hello Bello on a Shopify Plus website. The checkout is built in React/TypeScript. I also implemented the back end from scratch using Shopify Plus API, TypeScript, and NodeJS. The overall positive effect of this new checkout is about 20% better conversion rate.
Automated Data Migration Tool
I developed an automated data migration tool that enabled the company, AppFolio (NASDAQ: APPF), to take customer-supplied data from various competitive platforms, perform data transformations on them, and combine the data into a single database for a multi-tenant system. This enabled the company to close many complicated deals that were not possible earlier. The tool is now used for onboarding more than 75% of new customers.
Salesforce Talk and Blog | How Theragun Is Building 21st Century Customer Experiences
https://www.salesforce.com/blog/2019/09/theragun-21st-century-customer-experience.htmlI was invited by Salesforce.com to give a talk at their biggest eCommerce conference about the architecture I implemented at Theragun. I also wrote a blog post on Salesforce.com's blog about this.
The architecture comprised of Salesforce commerce cloud, a mobile app (written in React Native), and an API back end (written in Node.js). I integrated them with Salesforce.com, Salesforce Service Cloud, Twilio, and more, to provide a seamless experience for customers and access to all pertinent data of the organization in one place.

GraphQL API Back End in Golang
As the CTO for Wannago, I architected a GraphQL API back end using Golang for a restaurant curation platform. I developed the major parts of the back end and was responsible for deploying it on AWS. I recruited a team of two engineers to work on this architecture, including the author of the Golang Package Manager.
Salesforce Gem for Rails
https://github.com/appfolio/activeforceI developed an open-source Ruby gem for connecting a Rails application with the Salesforce.com CRM. This gem was the extraction of my work to implement a billing system and updating the CRM system with billing details.
eCommerce Monitoring and Alerting System Using Serverless Architecture
I came up with a way to monitor and alert the status of customer orders through the eCommerce, ERP, and fulfillment platforms using serverless architecture written in Ruby and Node.js. The system enabled the operations and customer service teams to get alerts for adverse conditions many hours, sometimes days, sooner as compared to previous manual methods in place.
Customer Service Portal
I conceptualized and implemented an internal customer service that allows representatives to issue appeasement for customers in lieu of missing items or mispacks. Technologies include React, Gatsby, TypeScript, Serverless, and GraphQL.
GraphQL API Back End for a Serverless Architecture for an IoT company, UVAngel, Inc.
I worked with the lead engineer to architect and implement a GraphQL back end using Node.js, TypeScript, and TypeORM, and deployed on AWS using Serverless.
The back end integrated with a custom MongoDB database and Cognito for authentication and also with an AWS IoT for device information.
