Hi, I'mMahesh

Full Stack Developer

I create elegant, high-performance applications with beautiful interfaces and exceptional user experiences.

About Me

Hello! I’m Mahesh Sivangi, a Senior Software Developer specializing in scalable, enterprise-grade frontend and full-stack applications for fintech, trading, and cloud-native platforms.

I specialize in high-performance UI systems, complex workflows, and component-driven architecture using React.js, TypeScript, JavaScript, Angular, and Node.js. I build reusable UI libraries, real-time dashboards, authentication flows, and data-driven interfaces for production applications.

My experience includes integrating RESTful APIs, WebSockets, and backend services to support dynamic data synchronization, user-triggered actions, and real-time trading workflows across high-throughput systems.

I have hands-on experience with advanced state management using Redux, Context API, and RxJS to manage asynchronous workflows, event-driven updates, and complex frontend application state.

Highlights include reducing UI-related bugs by 30%, increasing feature adoption by 40%, reducing latency by 50ms+, and improving response efficiency by 30% through optimized rendering and efficient data handling.

I also work with AWS services including EC2, RDS, S3, Lambda, API Gateway, CloudFront, and CodePipeline, along with Docker, Kubernetes, GitHub Actions, and Jenkins for cloud-native delivery and CI/CD workflows.

On the side, I build projects like Breeze, a real-time trading UI using React, TypeScript, RxJS, and WebSockets, and CryptoTrack, a Next.js and AWS-based cryptocurrency tracking application.
