sjultra, Inc.,
San Jose, CA - 2022/08 to present
- manager: Iben Rodriguez, +1 408-218-8957, iben@sjultra.com
-
I centralized system management of several RHEL/CentOS/Ubuntu hosts
using salt in multiple geographic regions across the U.S and Europe.
This can be scaled to 1000s of hosts whether they are virtual, hardware or
cloud-based hosts.
-
The configuratoin files for an increasing number of services have been and are
being converted to templates, including those for Postfix, OpenSSH, yum/dnf, rsync server,
user profiles, sudoers, chrony, firewalld, rsyslog, nginx, cron, datadog, dns client service,
and salt itself. User and group management is also centralized with salt.
-
OS/Application focus: Ubuntu/RHEL Linux, Nginx, OpenSSL, letsencrypt, SSL Certificates, certbot,
unison, Salt Project (formerly Saltstack)
-
Automating of SSL certificate generation with Letsencrypt using certbot

ThiveOn, Inc.,
Soquel, CA - 2021/03 to 2023/03

-
OS/Application focus: Debian Linux, Nginx, Gitlab, NodeJS, Strapi, Gatsby, Express, NextJs,
MySQL, rsyslog, rdiff-backup
-
The existing, informal application deployment process was redesigned to make it possible to
scale quickly to add new
applications, environments and servers. This included unifying the directory structure
for all applications, separating of read and write role users for security, using
rsyslog to feed file logs to journald, and using diff-based backups at deployment time
for easy reversion to older deployments.
-
All existing application deployment processes (Strapi, Gatsby, Express), most of which were manual, were
migrated to gitlab and this unified structure, and a new application was added (NextJS).
-
Development and staging envorinments were added to the production (the only existing environment),
bring the total number of application servers quickly from 2 to 7.
-
Extensive multi-way failover was designed and configured between all application servers
across all applications using CloudFlare and Nginx. This makes deployments seemless
and limits potentional downtime to a few seconds.
