01Introduction

About me

I build full stack products that are fast, structured, and easy to scale. My recent work spans end-to-end web applications, internal workflow platforms, and student-facing dashboards where frontend polish, backend reliability, and developer-friendly architecture all matter at the same time.

I work across the entire stack — React.js, Next.js, and Gatsby on the frontend, Node.js, Express, Sequelize, MongoDB, and MySQL on the backend, and GitHub Actions, AWS S3, and CloudFront for CI/CD and cloud deployment.

End-to-End Web Development

I build full stack applications from UI to API, balancing visual polish with robust backend architecture, database design, and clean deployment practices.

Scalable UI Systems

I create reusable component systems for dashboards, landing pages, and CMS-driven products so teams can ship faster without losing consistency.

Product Workflows & Automation

From bulk actions to job-stage flows and certificate generation, I turn repetitive product operations into reliable user-facing systems.

I set up CI/CD pipelines with GitHub Actions, deploy to AWS S3 + CloudFront, and automate build-test-deploy workflows for reliable, zero-downtime releases.

Recent work

Products I have designed, built, and shipped — from an AI code reviewer running on production repositories to the marketing, operations, and student platforms behind the Kraftshala ecosystem.

This Portfolio + AI Chatbot

The site you are reading, plus the AI assistant in the corner that answers questions about my work — both built, deployed, and monitored end to end.
