Hello
I am an experienced system engineer, and familiar with the LAMP stack, to be precise, my current occupation is integration and deployment. Kindly check my profile and recommendation (you can also check my linkedin profile).
I manage several dev, integration and production system.
Production system are deployed in HA, I use several techniques to implement it depending on customer budget, practices, and existing tool.
Then comes the tuning phase to reach response time target.
I'll put all my experience at your service to find the accurate root cause of this issue, relaying on monitoring data,and implementing it if ever missing, and fix it, and why not going beyond, integrating cache, minifying, CDN to make the site even faster...
I master the Mysql, and postgres database, and I am ready to tune the DB layer.
I look forward to collaborate with you.
PS : I am immediately available and we can try a first solution I experimented, and evaluate it today.
