Social Marketplace App

http://www.vendefy.com/
In this project, I worked on both the front end of a native iOS app and the back end using Java and Spring Boot with a Neo4J Graph database, fixing bugs, and adding new critical functionalities.

On the front end, I updated the existing UI, added new screens, and created integrations with the back-end server. In addition, I released several builds for testing, using TestFlight, as well as a complete build for production. On the back end, I fixed functional bugs, added integrations with Plaid and Stripe APIs, and implemented new business logic. In addition, I built and released the fixes to the production server. Finally, I reviewed customers' resources hosted on AWS and was able to reduce their AWS monthly bills by approximately $1,000.

The code was committed to the client's GitLab repository.

Dating Web Service

https://fireupdesire.com/
A pet project that I did to explore the Django/Django REST framework along with Angular 8 and HTML5 (Canvas). I designed and implemented the project from end to end, the infrastructure, and the deployment to AWS public cloud.

Shopify Store

An online store that I built on top of the Shopify platform, connecting it to payment providers, third-party apps, and enhancements. I did the translations as well as the UI modifications to support the right-to-left layout. In addition, I wrote a product scraper for the supplier website and a fully automated inventory and product sync lifecycle.

Shopify Store

http://tokyo-7.myshopify.com/
The project scope included:
1. Enhancing an existing theme with new sections
2. Customizing existing sections
3. Performing UI optimization for mobile
4. Integrating and customizing third-party apps

The project was successfully completed in a week for a US-based client.

Shopify App | End-to-End Development

The project was implemented with the following features:
1. Admin panel
a. Author and customize quizzes
b. Monitor performance
c. Help section

2. Storefront widgets
a. Embedded quiz
b. Popup quiz triggered by button
c. Popup quiz triggered by leave store intention

3. Host the app on AWS
a. AWS S3 for storage
b. AWS CloudFront for CDN services
c. AWS EC2 and ALB for hosting

The app was successfully deployed to Shopify's app store. Although this project was delivered, I'm still working with the client on new features and new apps.

Microservice Integration

Played an instrumental role in integrating the microservice into the existing systems. Starting with an integration SDK to a third-party service, it evolved into a microservice that offered abstract access to the service using Spring Boot on top of Java and PostgreSQL.

As a senior Java back-end engineer, I spearheaded the design and implementation of the project's back end. Within the project's scope, I collaborated with the UI team, developed unit and integration tests, managed dependencies, ensured security and authentication, and provided comprehensive documentation.

An Interactive Test-preparation System

Developed a successful interactive test-preparation system, despite several issues caused by a quick-and-dirty development approach in its early stages.

To achieve this outcome, I analyzed the root causes of the issues and proposed possible solutions. After working with the client to create a work plan, the system was up and running to their satisfaction.

Furthermore, I recommended and implemented an upgraded deployment approach, resulting in a more durable application.
