Patrice Levesque - Résumé

8039, Berri street
Montreal, Quebec, H2R 2H2


GNU/Linux system administrator.
15+-year experience.

On pre­vi­ous as­sign­ments, I ad­min­is­tered up to about six­ty servers, host­ing a va­ri­ety of ser­vices (web servers, data­bas­es, mon­i­tor­ing and alert­ing sys­tems, name servers, da­ta stores, e-mail host­ing in­fra­struc­ture, load bal­ancers, …). Some­times un­der au­to­mat­ed or­ches­tra­tion con­texts, of­ten us­ing vir­tu­al­ized servers, al­ways with high avail­abil­i­ty in mind.

I al­so held serv­er-side de­vel­op­ment and in­te­gra­tion roles on web ap­pli­ca­tions; my last ex­pe­ri­ences main­ly in­volved con­tent man­age­ment sys­tems. I mas­ter the tech­ni­cal web sci­ence, from net­work lay­er to client lay­er.

I aim to pur­sue sys­tem ad­min­is­tra­tion work, in a di­ver­si­fied re­spon­si­bil­i­ties con­text, on projects both stim­u­lat­ing and se­ri­ous.
