Backend and frontend engineering work on Azure signup, subscriptions, billing/payment and other commercial components

• Designed and developing a web application product using Vue.js, Node.js, Mongo for intra-project collaborations.• Did NoSQL data modelling with Mongo database, and programmed REST APIs in Node.js for React/Vue to use.• Developed dashboard for a cloud platform using React.js to let users interact with deep learning services.

• Implemented follow-up-orders feature in a telecom Order Execution Engine written in Java, which allowed users to append another subscription-order to a previous order. Helped business in boosting the total orders by 39.2%.• Led a team of six members to optimize four SOA-based Middleware asynchronous Service Compositions written in Business Process Execution Language, which reduced the probability of orders getting stuck by 3.6%.• Met and collaborated with clients in Eastern Europe, to establish system designs, which led to a $95000 project.

• Improved Order Execution Engine reliability by implementing a rollback mechanism in Java, that could store orders in queues during system failures and re-initiate them later, thus reducing the downtime by 31.8%.• Developed and presented an automated regression testing framework using Java and Groovy, as a part of Continuous Integration (CI), to enable early detection of bugs, thus reducing the overall release time by 40%.• Engineered a reusable TCP network socket server component in Java to enable cross-domain communication.• Wrote Bash Scripts and BPEL Sensors to extract real-time data from Middleware layers, and created web-based dashboards and alerts to let business users monitor orders-related information in customizable formats, thus helping them in making decisions.
