About

I build and look after the IT that businesses depend on.

I’m Inder Pal Singh Kochar – a freelance systems and network engineer with hands-on experience in India and Australia. I bring infrastructure, email and web engineering together to deliver systems that are secure, scalable and simple to run.

Background

Curious about technology from the start.

I’ve always wanted to know how things work – and how to make them work better. That curiosity became a career designing, deploying and supporting IT infrastructure: Windows Server and Active Directory environments, Linux servers, virtualised platforms, business networks and enterprise email.

Today I work with individuals, start-ups and established businesses as a hands-on technical partner. One week that means migrating a company’s mail to a new Exchange or Postfix server; the next, hardening a network, rescuing a slow website or building a custom WordPress plugin that automates a workflow.

Every project follows the same principle: you are what you build. Systems should be secure, efficient and scalable – and technology can be simple and powerful at the same time.
