Work Experience

Back-End Engineer

2017 - PRESENT
Homewings Ltd.
  • Built full-stack features (back- and front-end) involving moderately simple front-end tasks, and more difficult back-end architecture tasks from database design to API.
  • Increased the back-end coverage and test quality—achieving 93% coverage—and increasing the test cases for already covered code, finding and fixing small bugs before they actually happened.
  • Increased the organization of the development team, by partially applying Scrum techniques and acting as Scrum Master. The team size was not large enough for a full-fledged Scrum implementation so far; also added new tools for syncing business with the development team.
  • Upgraded the Ansible implementation and deployments of the platform, making it more robust; added Celery deployments and implemented Ansible best practices for security.
Technologies: Ansible, Django, Python, Scrum

  • Created a web platform with both public and private sites.
  • Managed customers, leads, and products.

  • Developed multiple APIs in Python supporting high throughput, RESTful interfaces, caching mechanisms, and with developer friendly documentation.
  • Created an IoT platform from scratch—including DevOps side (auto-scaling with AWS, deployments in Ansible, permissions, security), MQTT brokers with RabbitMQ and high availability clustering, an API for mobile devices to feed from the information of the devices, bidirectional communication, very high coverage and code quality monitoring, asynchronous tasks to monitor the status of the platform, and an admin site for managing the database and the machines with a permissions system.
  • Built from scratch the back-end of a website using Wagtail CMS with fully editable and dynamic content.
  • Stress-tested APIs.
