Shivam Arora

I am a full-stack software engineer specializing in building production-grade, scalable web applications and APIs using modern JavaScript and TypeScript across the entire stack.

Backend Development
I build robust backend systems using Node.js and Express.js, designing RESTful APIs, GraphQL services, and real-time applications using WebSockets. My APIs are built with production standards in mind: input validation with Zod, authentication and authorization using JWT, structured logging, and comprehensive test coverage using Vitest and Supertest. I also perform load and performance testing using k6 to ensure systems can handle real-world traffic before they go live.

Frontend Development
On the frontend, I build responsive, maintainable applications with React.js, using Redux for state management, React Router for navigation, and TanStack Query for efficient server-state and data-fetching logic.

Databases
I work with both relational and NoSQL databases, including PostgreSQL and MongoDB, using Mongoose for schema modeling and query optimization. I design database schemas with performance, scalability, and data integrity as core priorities, and integrate Elasticsearch for advanced search and analytics requirements.

System Design & Architecture
I have hands-on experience designing high-scale, production-ready system architectures, including microservices, event-driven systems using Kafka, and distributed application patterns that support horizontal scaling and high availability.

DevOps & Infrastructure
I containerize and orchestrate applications using Docker and Kubernetes, and set up monitoring and observability pipelines using Prometheus and Grafana to track application health, performance metrics, and system reliability in production environments.

Cloud & Hosting
I deploy and manage applications on AWS, Oracle Cloud, DigitalOcean, and Vultr, configuring infrastructure for scalability, security, and cost efficiency based on project requirements.

Payments Integration
I integrate secure payment processing systems using Stripe and Razorpay, handling subscriptions, transactions, and webhook-driven payment workflows.

Tooling & Package Management
I work efficiently across all major JavaScript package managers, including npm, yarn, pnpm, and Bun, adapting to whichever toolchain a project or team already uses.

Whether you need a new application built from scratch, an existing system optimized for scale, or a production-ready API developed with proper testing, monitoring, and deployment pipelines, I bring a disciplined, engineering-first approach to deliver reliable, maintainable, and high-performance software.
