E2E came to Toptal with a project for a full-stack engineer. They wanted to create an MVP that included onboarding new users, running them through a financial questionnaire to help categorize them, and then present portfolio recommendations to the user. One of the main things they needed was the financial questionnaire to be completely dynamic based on tables from a Postgres DB hosted in Amazon RDS. They have multiple surveys for users to go through, question types, sub-questions, and more. Upon completing the survey, we grade the survey, save it to the database, and present the user with Portfolio recommendations. We present this on a dynamic SVG donut chart that also drills down to a data table of information. To accomplish this, I set them up an AWS RDS Postgres database schema from scratch. I set up the API Gateway and Lambda functions to access the data and present it to the app dynamically. They presented me with a rough design and gave me room to redesign and write the entire React Native project based on my experience with previous apps. We managed to finish the MVP in two weeks, and they were very pleased to see the entire MVP working dynamically. They are currently in the process of raising capital for the next phase.

Invisible Hands Deliver is a non-profit organization delivering groceries and other essential items to populations especially vulnerable to COVID-19. I lead the engineering on the iOS and Android app while working closely with a design team and back-end development team. This app streamlines the current day to day operation they have setup with Slack. This app makes everything easier for volunteers and operations to create, communicate, and deliver requests to those vulnerable to COVID-19. This app is still in beta and will be releasing version 1 to iOS and Android in November.

I worked on the Marinate app for about two months and deployed it to the Android store using bare React Native. They had a full react web project working as well as a full Python API. They also presented me with a full Figma document to work from. I went through and replicated all their functionality from the web app while also integrating the Figma design one screen at a time. The application itself is described below:

Weather2020 has uses proprietary algorithms and models to help its clients forecast their businesses based on weather projections 6-9 months ahead of time. Their accuracy has been well proven out so they have begun investing in the IT portion of their company. That's where I came in. I developed a multi-tenant platform and iOS/Android App to allow for different levels of users to view the data and analytics that weather2020 provided. Some pages provided visualization of the weather data all the way down to a specific zip code six months out aggregated into a week by week period. I was responsible for building all the visualization of the data sets that were given to me to make the information useful to clients. Certain clients also have special integrations and reporting models based on the information they paid for. The platform also had a free tier that let generic users sign up for the app and view limited data from their phones. The backend portal is protected but you can view the company website to learn more about what the platform can do.

I recently had a yoga instructor reach out to me asking for help building a video platform for all her subscribers. Due to COVID-19, she would no longer be able to host classes at her studio so she wanted to do it all virtually and have it be organized. So she and three other studios pitched in to pay for me to create a video platform. The platform's main features allowed users to sign up and subscribe to different classes. Their account would have billing set up and used Stripe integration to charge them on a monthly basis for the classes they are taking. The classes would have prerecorded videos for them to follow form home and also they had a zoom tab that allowed them to join live classes via Zoom integration into the platform as well. On the admin side, the yoga instructors could setup classes and upload videos to their cloud. All media was hosted in Amazon S3 to keep it all private rather than using youtube. They were also able to create new zoom classes and post them to the user side. The platform basically allowed them to have a virtual yoga studio during the COVID-19 quarantine time.

A multi-tenant cloud platform for housing customers data and images. Customers had photos and data attached to every piece of freight that was sent to our cloud via private API that I also created. Using AWS, RDS, S3 we stored all our data in the cloud. This project was mostly done with Javascript, React, Reactstrap, PHP, Node.js, and MySQL. The system was still taking in over 500,000 records a day and scaling up while only being supported by one developer which I trained before departing the project at its completion.
