Full Stack Developer
building web apps that actually ship.

I'm Ajay Kumar, a Full Stack Developer and Freelance Web Developer based in Panipat, Haryana, India. I design, build, and deploy production web applications using React, Django, and Node.js — from the database schema up to the pixels on screen.

About Ajay Kumar
A bit more about the developer behind the code.
Ajay Kumar — Full Stack Developer

I'm a Full Stack Developer with a solid grounding in web technologies, AI/ML, and data science. I like building web applications that solve actual problems — not just writing code, but understanding why a feature needs to exist, then designing an interface, backend, and database around it that hold up in production.

I currently work as an Assistant Software Developer at Geeta University, where I build and maintain web applications, ship new features, optimize performance, integrate APIs, and automate internal workflows. Day to day, that means React, Django, Flask, Node.js, PostgreSQL, MySQL, MongoDB, Docker, Nginx, and GitHub Actions — so I get exposure to the full development lifecycle, not just one layer of it.

Outside full-time work, I take on freelance web development projects under my own brand, and I have a background in Machine Learning — building predictive models and data-driven tools with Python, Scikit-learn, TensorFlow, and Keras. I also write about real deployment issues and lessons learned on my blog, mostly things I had to debug the hard way.

What I Do
As a Full Stack Developer, I work across the whole stack — backend architecture, database design, and pixel-level frontend work — to ship web applications that hold up in production.

Backend Development

I build the backend systems that handle authentication, business logic, and data workflows for web applications — architected to stay maintainable as the product grows, not just work on day one.

DjangoFlaskNode.js

Frontend Development

I build responsive, component-driven React interfaces that stay fast and usable across devices, with an emphasis on clean UX and interface pieces you can actually reuse.

HTML/CSSReactJavaScriptBootstrapTailwind

REST API Development

I design and integrate REST APIs that connect frontend, backend, and third-party services cleanly, with predictable request/response structure and proper error handling — not silent failures.

Database Design

I model relational and document databases around how the application actually queries data — balancing normalization against real query performance, in MySQL and MongoDB alike.

Deployment & DevOps

I handle deployment end to end — server setup, Nginx config, and CI/CD pipelines — so applications ship reliably and stay easy to maintain once they're live.

SEO & Performance

I optimize page speed, accessibility, and on-page SEO so sites load fast for users and are easy for search engines to crawl and rank.

Web Development Services
Whether you need a full product built from scratch or one specific piece of the stack handled, here's where I plug in as a freelance web developer.

Website & Web App Development

End-to-end web application development — from initial architecture to a deployed, production-ready site — using React, Django, or Node.js depending on what the project actually needs.

Backend Development

Secure, scalable backend systems covering authentication, role-based access, and business logic, built with Python, Django, or Flask.

API Integration

Integration of third-party and internal REST APIs, with clean data flow between frontend and backend and error handling that doesn't fail silently.

Database Design

Schema design and data management across MySQL and MongoDB, structured around how your application will actually read and write data day to day.

Performance Optimization

Auditing and improving page speed, SEO, and responsiveness so your application performs well for users and ranks well in search results.

Maintenance & Support

Ongoing debugging, feature updates, and deployment maintenance to keep existing applications stable, secure, and up to date.

Have a project in mind, or need a full stack developer on your team? I'm currently open to freelance work and full-time opportunities.
