Wrote comprehensive documentation for the services using swagger and learned and practiced clean architecture and mono-repo in Go.
Developed small Go applications that unzipped and parsed CSV, JSON-formatted, and huge data in concurrent (parallel) processes. Wrote the read models to PostgreSQL or MySQL databases.
Worked with many Go libraries such as sqlc, Go Cron jobs, in-memory caches, Redis, JWT (JWA, JWK), Auth0, Recurly, and many more.

Experience

Dailywire+

https://www.dailywire.com/

A Go-based microservices for the media platform that includes:
• Content service
• CMS service
• Subscriptions service
• Chat service
• Email service

Besides these services, I developed tools such as database schema migrations, webhook handlers (Auth0, Shopify, Braze, Recurly), and email service integrations (Mailgun and Braze).

I was introduced to BDD testing: Cucumber with Gherkin. We used Godog.

I was mainly the back-end developer. However, I also contributed to React-based projects requiring small features or bug fixes.

A Card-issuing Microservice

A Go-based microservice (a part of a bigger platform) for card issuing and financial transactions using Stripe's card issuing and onboarding services (integration with Stripe APIs). I was responsible for designing and creating the microservice using Go.

AACOMPLISHMENTS
• Created an API for card issuing and financial transactions (sending and tracking).
• Worked on creating cron jobs, scheduled processes, and audits for missed transactions.
• Provided support after the project was completed in an ad hoc capacity.
• Handled Stripe webhooks.
• Secured the endpoints using JWT-based authentication between microservices.

Baraka | eCommerce App

• Helping the project owner to translate business requirements into technical requirements
• Contributing to the overall system architecture by proposing optimal solutions and essential technologies to benefit the business
• Developing, testing, and deploying a Java application into a server in Digital Ocean
• Implementing best practices and code reviews

I contributed to a large portion of this system, especially in searching and filtering, real-time chat using WebSockets and RabbitMQ, and generating PDF reports. In this project, I have integrated our system with payment processing systems such as PayMe, Click, and PayNet.

P2P Payment Services for Hamkor Mobile Banking System
