As a member of the team that is building internal tools for Bulbs' energy specialist, I've been involved in building many tools but also integrating third-party services into our every-day processes. Bulbs' main stack is TypeScript/React.js/Node.js and are using Terraform to manage our platform provider and Kubernetes to manage our runtime services. I've been involved in different side projects as well, from security to onboarding. As a senior engineer, I led several projects, by braking them down, designing the architecture and planning the release from zero to production.
In a very fast paced environment and a small, I participated in many decisions and involved in many parts of the product teams' process. As a member of the consumer squad, I designed and built an integration with Shopify that would allow our customers to be in sync with our platform. As a member of the platform squad, I involved in many DevOps operations, building and re-architecting existing parts, writing documentation and helping in defining engineering processes. I was also helping other team members to when blocked in designing extensions of our system in a micro-services architecture. We were using Node.js for our backend services and React.js/Ember.js for our frontend apps. Our architecture was built on AWS (ECS for VMs, SQS/SNS for intercommunication, and others).
As the lead developer in a team of three, I helped set up the infrastructure for the Quotelier platform and apply best practices to both the backend and the frontend blocks. We chose AWS for our infrastructure and used many services like AWS Lambda and DynamoDB. I have worked with both the backend project, built completely on AWS Lambdas with Node.js. I ‘ve also worked on the frontend project, built with React.js and helped set up the testing strategy and raised the code coverage of the whole codebase.
Being the fourth engineer, I helped the company grow its platform from an MVP to fully scalable, modularized architecture that was servicing thousands of requests per day. I have developed the backbone REST API that served the Goodvidio service using Node.js. I have participated in the architecture build process that was designed to serve an application that would scale fast. We payed attention on our testing strategy and kept keeping a high test coverage.
I helped the InsightReplay team with the front end development of their product while working closely with Angular.js 1.x.
Working mainly with E-Commerce businesses, I had the opportunity to work on the world’s most valuable E-Commerce platform, Magento. I have written a lot of modules and created many custom design themes.
