• I joined DevX as the most senior engineer on the team after the CTO, with a primary focus on validating and overseeing technical work across multiple fronts, including business logic, GitHub workflows, AWS infrastructure, billing, project scopes, and deadlines.
• Code Review & Agile Development Practices (Node.js, Express, NestJS): Led the PR review process, mentoring junior engineers and establishing an agile development workflow with structured GitHub PRs, branching strategies, and ticket formats. Regularly reviewed pull requests, handled merges, and managed releases to ensure high-quality, scalable code.
• Backend Architecture & Cloud Infrastructure: Worked on serverless (AWS Lambda) and Fargate-based Express/NestJS projects, optimizing build sizes, improving execution efficiency, and guiding developers on best practices for writing Dockerfiles, AWS infra, and API performance optimizations.
• Infrastructure as Code & Cost Optimization: Designed and maintained AWS SAM templates for Lambda functions and Fargate containers, ensuring cost efficiency, security best practices, and performance tuning. Personally wrote and optimized infra templates to minimize costs without compromising on scalability.
• Database & Performance Optimization: Reviewed DynamoDB data patterns and mentored juniors on designing the right access patterns based on API use cases, preventing inefficient queries and reducing operational costs.
• Solution Architecture for Startups via AWS APN Portal: Acted as a Solution Architect on the company’s AWS Partner Network (APN) portal, specializing in startup cloud infrastructure. Consulted multiple startups on AWS migrations, infrastructure planning, pricing estimates, and Solution of Work (SOW) documentation. Provided knowledge transfer sessions to ensure smooth handovers.
• 💡 Working with startups and optimizing AWS cloud architectures has been a rewarding journey! Always open to discussing scalable, serverless solutions. 🚀

• Worked as a Backend Engineer using Node.js, PostgreSQL, Express, GraphQL, and Sequelize, contributing to major system rebuilds, codebase optimizations, and testing automation.
• Led the rebuild of the onboarding server from scratch, analyzing 4+ years of Node.js code to fully document missing business logic on Confluence for long-term maintainability.
• Upgraded Node.js from v14 to v18 LTS, removed deprecated dependencies, resolved DependaBot alerts, and restructured the project using Clean Code Architecture for modularity and reusability.
• Achieved 30-40% faster new user registrations by improving database transactions, reducing bottlenecks, and implementing best practices.
• Implemented Jest-based unit testing, setting up a robust testing framework for onboarding services.
• Developed comprehensive test cases, ensured pipelines validate new changes before PR merges, and increased overall code coverage to 80%+, reducing production failures.
• Designed and built a feature-rich Postman collection to improve API testing and automation for the onboarding server.
• Configured authentication modules, collection & environment variables, and Postman scripting to streamline the QA process.
• The new Postman collection significantly enhanced testing accuracy, reduced debugging time, and improved QA engineer productivity across the onboarding team.
• 💡 Loved solving complex backend challenges at Novo and refining Node.js architectures for scalability and performance! 🚀

• At AppGambit, my journey into Node.js and AWS began in 2019. My first experience with AWS SES in a Node.js Express project, using the AWS SDK, sparked my deep dive into cloud backend development. From that moment, everything changed.
• The Journey from Writing APIs to Mastering AWS Serverless
• Mastered writing backend business logic in Node.js, starting with Express services and evolving into Serverless applications. Learned to package, deploy, and manage Lambda functions using Serverless Framework and CloudFormation stacks.
• Discovered the beauty of DynamoDB and mastered its NoSQL access pattern design. Grateful to the company's great founder, who personally guided me in structuring NoSQL data efficiently, ensuring optimal performance without traditional SQL joins.
• Explored and implemented nearly every possible AWS event trigger for Lambda functions, including API Gateway, AppSync, SQS, SNS, Cognito, EventBridge, Alexa Skills, Lex Chatbots, and Amazon Connect IVRs—gaining full-stack event-driven architecture expertise.
• Developed a deep understanding of AWS IAM, learning how resources communicate securely through IAM roles and custom policies. Understood principle of least privilege, resource-based permissions, and best practices in securing AWS applications.
• Worked with AWS Step Functions early in my career—processing millions of NGO feedback documents daily to calculate NPS scores. Explored state transitions, parallel execution, and overcoming AWS Lambda’s 15-minute execution limit. A huge thanks to the founder, whose mentorship allowed me to work on real, large-scale use cases.
• 💡 I couldn’t have asked for a better first company than AppGambit—or a more inspiring mentor than the founder himself. Forever grateful! 🚀
