- Backend Development with Fast API: Built the backend for Picarro’s Next-gen Mobile App, focusing on scalability and maintainability. Key initiatives included: - Setting up the initial project structure with organized code listing and effective package management. - Establishing one-click development environment setup using Dev Containers across the whole team. - Implementing GitHub Actions for automated code quality checks and continuous improvement. - Integrating Ruff as a linter to enhance code quality and achieve significant performance gains. - CI/CD Optimization: Established Pipeline-as-Code in Jenkins for consistent, version-controlled CI/CD. Optimized pipeline structures and implemented best practices including pipeline parameterization, secure credential management, and branch selection to streamline deployment and improve control. - AI Tool Efficiency Testing: Evaluated the efficiency and productivity impact of GitHub Copilot for code generation and error reduction, providing insights on its adoption for the development team. - AWS Migration: Led migration of SQL Server Databases and SSRS from EC2 to AWS RDS, including RDS configuration, EC2-to-RDS database restoration, IAM roles management, and configuring SSRS data sources. - Backup Optimization: Devised 3x faster SQL Server backup mechanism using AWS CLI and S3, reducing backup time from 15 to 5 hours. - Feature Enhancement: Enhanced customer experience by implementing real-time map rotation for PG&E surveys. - Microservices Development: Developed Python 3.6 microservices for reports processing using AWS EKS, SQL Alchemy, Celery, and Flask. - TDD Implementation: Introduced TDD practices in C# and Python, cutting feature development time by 30%. - Process Improvement: Designed master checklist-based sprint retrospectives, increasing sprint velocity by 25%.

- Accelerated web page load times by ~100x (14 sec to 140 milliseconds) through server-side dashboarding and query optimization. Implementation included query plans analysis, and Dynamic LINQ generation with C# Expressions, Generics, and Lambdas. - Designed and developed Python 3.6 OTA (Over the Air) upgrader utility for upgrading Picarro surveying cars. Features included asynchronous upgrade download and installation, SHA256-based file verification, cloud-based upgrade control and monitoring, and failed upgrade recovery mechanisms. - Prototyped a replacement of SignalR with gRPC and gRPC-Web for real-time stream communication. - Implemented C# REST API for automatic transfer of failed survey reports, expediting error resolution.

- Developed .NET C# console utility for automating the process of detecting and leveling up the differences in DB indexes in a multi-node Couchbase cluster. Build CI/CD pipelines for build and deployment using Azure Pipelines to deploy across different environments viz. Dev, SQA, and production. - Day-to-day responsibilities included bug fixing, rolling out new features based on design patterns and pair programming. Technologies included .NET C#, Couchbase, CI/CD Pipelines, Test-Driven Development using MS Test framework and Moq, Azure Pipelines.

- Developed serverless chat application for simplifying the communication between online course instructors and students at ASU.Used ES2017, Node.js, Twilio API and Amazon Web Services viz. Lambda, Dynamo DB, API Gateway as the technology stack.- Developed Single Page Applications using Vue.js and integrated into edX Studio to provide enriching course experience to students.Worked closely with course designers and instructors to understand the requirements of applications.

- Responsible for grading weekly programming assignments for CSE 220- Programming for Computer Engineering.- Reduced weekly grading time from 10 hours to 4 hours by automating grading procedure using Bash scripts.

- Developed Cross-platform administrative dashboards for Change Order Request Engineering System featuring interactive data visualization on grids, tree views, and charts. Implemented UI using Telerik Kendo UI, AJAX, and jQuery.- Reduced module development time across the team by up to 40% as measured by weekly deployments by advising the use of jQuery components instead of .Net components. This led to quick experimentation and shallow learning curves.- Accomplished 50% faster database query times as measured by SQL Server Profiler by implementing query optimization techniques like reducing table joins, data indexing, maintaining views for frequent data accesses, stored procedures for improved modularity. Implemented using Entity Framework v6.- Collaborated with cross-functional teams and foreign clients regarding software requirements, module development, software testing, and on-time delivery.- Proactively led the software module development during peak delivery times
