About Harsh Panchal
I’m Harsh, a full-stack developer and data professional who loves turning ideas into working products. I specialize in building modern web applications using Next.js, React, Node.js, and MongoDB, combined with strong experience in data analytics and ETL.
My work sits at the intersection of engineering, data, and product thinking — taking a raw idea, shaping the architecture, and shipping something real that users can depend on.
What I Do
Full-Stack Web Apps
I build modern web applications using Next.js, React, TypeScript, and Node.js, focusing on clean components, predictable flows, and UIs that feel smooth and intentional.
APIs, Data & ETL
I design secure APIs, integrations, and ETL workflows that keep data flowing correctly. From MongoDB and PostgreSQL to Power BI and Excel automation, I connect engineering with analytics.
AI-Powered Features
I integrate the OpenAI API and AI tooling into real products — from smart recommendations and content generation to assistants that help users and teams work faster.

Journey So Far
Built a fully editable portfolio with a custom Admin panel to manage Projects, Skills, Experience, and Pages — focusing on architecture, reusability, and clean UX.
Worked on BI dashboards, ETL workflows, and web apps that combine analytics, data storytelling, and AI-assisted features for decision-making.
Shipped real features with React/Next.js, Node.js APIs, and MongoDB — focusing on auth, role-based dashboards, and real business flows instead of just demos.
Designed and maintained ETL pipelines, automated reports, and close collaboration with business teams to translate requirements into reliable datasets and dashboards.
How I Work
I care about more than just “making it work”. I focus on building things that are maintainable, secure, and easy for teams to extend.
- Clear architecture and folder structure future developers can understand.
- Secure authentication, authorization, and data handling for real users.
- Clean, consistent APIs with validation, error-handling, and documentation.
- Readable, maintainable code instead of one-off quick fixes.
- Developer experience: scripts, environment strategy, and CI/CD pipelines.
