Aaron C. de Bruyn

Launched a business to support a number of clients, with a focus on small businesses and medical. Designed and released a packaged solution that addresses HIPAA-compliance issues that can scale from small practices to large enterprises. Provided a stable network environment, reduced infrastructure costs, implemented measures to protect patient data, provided disaster recovery services, monitoring, alerting, and user support. Built in-house tools for data analytics, APIs to interface with various RMMs, remote access, ticketing, and information management with a heavy focus on automation to reduce costs.

Worked with Linux, FreeBSD, Windows, Asterisk, Eaglesoft, Dentrix, ELK stack (Elasticsearch, Logstash, Kibana), Saltstack, Python, Django, virtualization, and Kubernetes.

Designed and built intfrastructure to support a cloud-based managed intrusion detection service as well as providing support to customers and sales teams for auditing and compliance reporting using FreeBSD, Docker, Kubernetes, Suricata, Python, Django, Elasticsearch, Logstash, Salt.

Developed a variety of products designed to enable managed service providers to remotely support and manage their client networks. Technologies primarily consisted of Django, Node JS, Visual Basic, and C# along with tools like Redis, Postgres, Elasticsearch, HAProxy, Docker and Vagrant.

Worked remotely as a Developer on a secure communications application using several technologies including Django, Salt, MySQL, Apache, Vagrant, Node.js, Mongo, and Redis. After project completion I transferred to the commercial services security division to work as a systems engineer managing and supporting the intrusion detection ecosystem involving technologies like Elasticsearch, Django, Salt, Node.js, MySQL, Nginx, MongoDB, Snort, and Bro until a corporate restructuring shut down the commercial intrustion detection services division.

Working as a systems engineer for a family-owned business serving a wide variety of clients that need network design, management, and support without the cost of employing full-time IT staff.

My primary clients include:

• A large network of approximately 32 sites connected via VPN links over the public internet. Their primary dental applications are Windows-based, however the routers and firewalls are FreeBSD-based, and each site has at least one Linux server to provide virtualization of their Windows infrastructure. Additionally there are a handful of Linux servers provide intra-office messaging, e-mail, management, monitoring, alerting, spam filtering, and off-site backups.
• A large manufacturing facility where I assisted in maintaining the production network computers, thin-clients, printers, PLCs, and Linux servers. I also deployed a Linux-based VoIP and Fax server using Asterisk to help replace parts of their ancient analog phone system that was costing thousands of dollars in contracting fees every month. Phones were replaced as analog pairs degraded or were cut during various construction / demolition projects.
• Three government agencies in one building, each with their own unique requirements and an extremely limited budgets. I designed and implemented several low-cost solutions including replacing 4 old virus-infested public access computers running Windows 2000 in their library with 12 thin clients in a Linux Terminal Services Project environment for several thousand dollars less than the comparable Windows solution. For over 3 years, my monthly maintenance in their Library consisted of asking if there were any problems, being told "no, things are running perfectly", and then returning to my office with an upgrade to a newer release every 6-8 months.
• A multi-site government network with 4 locations that required network connectivity to their vehicles. I replaced a cellular routing appliance in each vehicle that did not perform to vendor-advertised standards with embedded Linux routers that communicated securely back to a central office so ambulances could access patient data and call information while en-route to 911 calls. I also managed their virtual server farm, storage network, and their fiber backbone.

Ran a small web hosting provider involving a handful of Linux servers. Hosted sites for clients, friends, and family. The project was an experiment to test the security and automation capabilities of Linux in a production environment.

I volunteered from January 2001 until February of 2005, at which time I was hired on part-time. In September 2005 I was brought on full-time. While on-duty, I responded to 911 requests for assistance aboard an ALS ambulance and/or technical rescue vehicle. Duties included providing patient care, teamwork, critical thinking, disaster planning, problem solving, and rapidly changing environments and command structures on emergency incidents. I also helped maintain IT systems for the service.

Provided support on an on-call basis to numerous companies and individuals in the Columbia River Gorge area, providing phone, e-mail, and on-site support for a variety of Windows and Linux networks.

I designed and developed web-based applications for customers and for internal use. I designed and maintained the company intranet, including business applications for tracking telephone circuit repair, installation of new services, and interfaces for support personnel to monitor various network device logs relating to customer accounts.

I was regularly tasked with installing and configuring new hosting servers and co-location machines in addition to new employee workstations. I was on-call 24/7 to support critical infrastructure that kept an average of 1,000 users online at any one time.
