Colombo, Sri Lanka

Hi, I'm Ajinthan.
I build web apps.

Building scalable web & mobile platforms — high-performance apps, microservices and real-time systems in .NET, NestJS, Next.js and Flutter.

About me

Hello — I'm Ajinthan, based in Sri Lanka.

With 5.5+ years building scalable web and mobile platforms across e-commerce, transportation, tourism, trading and CRM systems — specialized in high-performance applications, microservices architectures and real-time systems.

Strong expertise in .NET, NestJS, Next.js, Express, React and React Native, with hands-on experience in API design, cloud deployments, WebSockets and distributed systems — plus a proven track record integrating multi-gateway payment systems for both Sri Lankan and global platforms.

I deliver end-to-end solutions, from architecture and development through to deployment and optimization, while collaborating in agile teams and driving product scalability. I'm passionate about reliable, scalable, user-focused software that creates real business impact.

How I build

An agile loop, not a straight line.

Every product moves through the same cycle — then goes around again. Ship, learn, refine, repeat.

What I do

Services, end to end.

From the database to the pixel — and the camera when the moment calls for it.

Web Development

Websites built with React.js and Node.js — Node handles the backend with MongoDB or MySQL; React and Redux drive a scalable, responsive frontend. For SEO, Next.js delivers top-notch sites.

Mobile App Development

Cross-platform apps with React Native — Expo or Native CLI based on the project. A Node.js backend, MongoDB or MySQL for data, all connected through a clean REST API.

Search Engine Optimization

For SEO-centric projects I use Next.js to lift rankings, paired with Google Search Console and Analytics for in-depth analysis — ensuring effective strategies and continuous improvement.

Photography

Capture the moments of your convocation with professional event photography. Book your convocation photoshoot for high-quality images that commemorate the occasion.
