• Created Github Actions workflows for 10+ repositories during the migration from Jenkins to Github Actions• Developed a Python script to monitor workflows using Github API’s and auto-generate emails with the data• Built multiple Grafana dashboards by querying a PostgreSQL database to visualize builds on Github Actions• Resolved developer pain points through automation as an initiative of Developer Productivity Engineering

• Increased the team’s monitoring capability by configuring proactive email alerting when used disk space on build servers exceeds a threshold by integrating AlertManager into Prometheus• Deployed the alerts service as a Docker image using Ansible playbook as an initiative of developing self-healing infrastructure• Centralized the resigning of vendor apps by combining the Android and iOS Jenkins jobs using Gradle automation• Integrated shared libraries across 30 CI/CD pipelines, reducing manual work and enabling quick code changes• Resolved multiple DevOps related issues on Jenkins eliminating blockers in the deployment pipelines

• Investigated a major issue in the communication channel shared by the trading platform’s 60+ servers using C++ and GDB and implemented a patch with changes to the event queues carrying UME messages.• Developed code to automatically monitor and collect statistics from the data generated by the LBM API and configured a server to listen for real-time notifications of lost messages and post logs with timestamps.• Fixed 10+ bugs during the centralize cache project to migrate 50k+ user account’s data to Redis external cache.• Built RPM packages with Jenkins to deploy the fixes and pushed binaries to JFrog Artifactory for testing.• Created a market data validator to check for invalid market data types, validate SIN numbers, and catch duplicate orders

• Transformed the reminder web application to a 10+ screen cross-platform iOS mobile application using React Native, increasing user retention and signup by 40%.• Implemented user-friendly features such as persistent login, pull-to-refresh, tabs to easily switch between screens, search-bar, swiping functionality to edit and delete reminders.• Replaced a paid speech-recognition API service for a video-meeting application's live transcript capture feature, with a free-to-use React plugin, saving $1000 monthly in costs.• Built RESTful APIs in the backend Express server to update and delete the action items stored in MongoDB as per user's request and tested their functionality using Postman API client.• Created advanced features for the upgraded plan which included dark mode user interface, attachment download capability and filter-based segregation of set reminders.• Debugged the app using XCode's iOS simulator and deployed it on TestFlight for internal team testing and feedback.• Designed Android specific user-interfaces in Figma as a part of the app's next deployment stage.• Received an OUTSTANDING evaluation from employer.

• Implemented new features for a video-meeting application using the MERN stack, such as live-transcript capture, meeting report-builder, vocabulary tab, and pre-made templates, using Socket.IO library to communicate user specific data between the client and server.• Increased application efficiency by 15% by replacing React classes with hooks and reduced API cost by optimizing code to make less frequent server calls and instead reuse fetched data.• Enhanced a reminder web application with new features, such as edit tags functionality and creation of new tasks, developed using Material-UI components and deployed them on Heroku.• Fixed bugs in the Express server related to unpredictable reminder confirmation emails being sent to users and removed vulnerabilities in the web application to improve the overall user experience.• Received an OUTSTANDING evaluation from employer.

• Performed UAT testing and validation of code to migrate an entire database from Amazon AWS Server to an in-house relational database by writing various SQL queries in Oracle, SQL Server and PostgreSQL.• Created test scripts to validate the bill run process and compare of the counts.• Migrated tasks for different billers from one remote server to another and documented each task in Confluence.• Created a content management system for the team to organize documents.• Worked with Agile (Kanban) and collaborated effectively with the team on task progress daily through JIRA and scrum meetings.
