  • Amazon SQS Console

    AWS SQS Console is the web UI customers use to manage their queues on AWS. I was one of two engineers who worked on building this console from the ground up with a high-quality bar for both engineering and operational excellence, as well as a modern UX and technology stack. After the initial release, I worked on multiple projects adding new features and enhancing the monitor-ability and test-ability of the service. I also worked on migrating the whole thing to a cloud-native serverless architecture.

  • Yaoota!

    Yaoota! is a price comparison website. I worked with Yaoota! as a senior back-end engineer on all system parts. I started with SQL tuning, optimizing search engine optimizations, implementing single sign-on (SSO), enhancing CI/CD tools, and others.

  • BlooWatch

    The first software for watersports and outdoor schools. I joined this project in 2017 as a part-time freelance back-end engineer. I participated in adding new features to the system, like scheduling classes for students and instructors and the rental of sea sports equipment.

    I Dockerized the application for use in development and production using Docker Swarm. I also managed deployments using Ansible and Docker Swarm.
