Work Experience

Innoloft, Germany

Full-time Back-end engineer. February 2021 – Currently

Their recommendation letter.

  • Gained experience developing, and deploying ASP.NET Core applications to the AWS cloud platform, and have worked extensively with the many services that AWS offers for building, deploying, and scaling web applications.
  • Developed, deployed, and maintained critical, resilient, client-facing features and exposed north to 150 API endpoints.
  • Was a key information point for Entity Framework. Introduced my team to many techniques, such as code-first (everywhere in our system we now use code-first).
    • Developed a customizable library that sits between the service code and on top of EF and helps Innoloft developers connect to multiple instances of the same database, it writes to the master DB and reads from one of the DB replications seamlessly without the need to change any code. Read more.
  • Migrated large chunks of code from a legacy monolithic service to modern and simple microservices seamlessly with 0 downtime.
  • Improved the system architecture by introducing the concept of functionality/data packages to the team. we were able to add functionality to a service and save data alongside the service data, greatly simplifying and sharing CRUD code while maintaining the service data sovereignty. The team was enthusiastic about this approach, and to date, we have developed six packages, two of which I personally coded:
    • A CMS library, which affected almost every service in the system, minimizing the CRUD code repetitiveness for managing content management rules, while exposing interfaces for the client service to implement in order to tweak the library behaviour to match the service needs.
    • A library for managing invitations across multiple modules, which led to a 7% increase in user count over a 10-month period.
  • Worked with various third-party services and libraries to build robust and scalable web applications. One of the services I am particularly familiar with is Mailjet, a popular email marketing platform. I also worked with DeepL and Azure translation.
    • Improved the resiliency of our inter-service communication by using Polly.
  • Worked with various databases, including MySQL, Elasticsearch, Redis, and DynamoDB.
  • Defined the coding style for the whole team by authoring .editorconfig and adding Huskey hooks to the git repositories to ensure that the styling rules were respected.
  • Created a CLI tool in my free time for developers/testers/customer support, it optimized our internal bug tracking/fixing process, it can generate JWTs for system users and hash IDs using the Hashids.Net library that we heavily depend on throughout the whole system.
