You can contact me if you need any consultancy help.

If you need help with a Linux or coding problem, I’m available for hire as a consultant.

My career has been focussed mostly on Linux servers, PHP development and management & I’ve been blogging about this for more than a decade.

If you need help with a technical problem, I can help as an independent consultant. Here’s what I’m good at.

  • Database servers like MySQL / MariaDB and limited experience with PostgreSQL
  • Caching technologies like Redis
  • Modern PHP (7.x and higher)
  • High availability setups, cloud & on-prem
  • Scaling your application beyond a single server (load balancing, failover, scale-out, horizontal scaling, …)
  • Server security
  • Troubleshooting (pretty much anything)


  • PHP
  • Architecture & design
  • Implementing caching strategies
  • UI/UX

Product development

I master several low-level protocols like DNS, HTTP & TLS.
