Tim’s Resume

This is the summary resume for Tim Kehres.  A detailed chronology of my experience is found on my personal website (interactive and easy to navigate).  More in depth details are on my Experience Details page and the Frequently Asked Questions page.

I am a senior systems architect and technical strategist with over 40 years experience designing, building, documenting and stabilizing complex infrastructure.  I help companies avoid costly mistakes and scale reliably.  I have a successful track record in the design and implementation of cutting edge systems and applications. Am able to combine market / financial research with technology to establish sound and profitable business strategies. Accomplished manager with International experience spanning the USA, Europe and Asia. I bring full lifecycle experience (startup through operational) with a breadth of experience across disciplines applying long-term systems thinking to bring business and technical requirements into alignment.

I am a US citizen and run my consulting business through my San Antonio, Texas address where I also have local phone access and US banking.  I maintain full US government tax and FICA compliance making it very easy to work with me for US companies.  I work out of my fully connected office in the Philippines and also maintain a small data center presence in Hong Kong.  Flexible working arrangements allow me to overlap client operating hours or use a follow-the-sun approach as needed to best accommodate client needs.

Current Projects

My current focus involves experimenting with several local AI models running on our hardware. The intent is to be able to easily create templates for local AI applications for our use and later for partner companies using local proprietary data.  Other projects include the Unified Security Framework, Distributed Web Services, and the Jade prototype project sites For more information please contact me and I can share more specific details and possibly access to some of our test systems.

Consulting Services

I provide consulting services in the areas of Business and Technology Strategy and Planning, Systems Engineering, Infrastructure, Business and Technical Writing, Software Development, and IoT Design. Solutions include design, deployment, audit, capacity planning, and the security and monitoring of enterprise class servers, services and networks.  You can find more details on my Consulting Services pages.

Strategy and Planning – Specializing in business and technology strategy and planning, I provide Strategic Technology Advisory for the AI Era.  The core mission is to work together with and guide established enterprises, startups, and investors through the full lifecycle of technology-driven transformation.

Systems Engineering – I provide end-to-end expertise for modern infrastructure. In today’s environment of AI workloads, cybersecurity threats, and pressure to modernize infrastructure, organizations need more than generic cloud advice—they need proven solutions that spans decades of real-world deployment.

Infrastructure – I help take the guesswork out of the design, operation, and expansion of your networks and applications.  This includes operational areas including system, network, physical security, disaster planning and recovery, policy planning and analysis, server, application and network audits, data protection, and asset management.

Business and Technical Writing – I provide business and technical writing services in Enterprise Architecture, Security, API and other reference materials, RFPs, Business Plans, Marketing and Sales collateral.  Deep domain and hands-on engineering experience help me create authoritative, clear, and concise documents that readers can easily understand.

Software Development – I design, build, and run systems in high-availability environments including mission-critical code (C/C++, Python, JavaScript, jQuery, Shell, and Perl) in real-world Internet and data-center settings I bring full-stack networking expertise—from low-level sockets to high-level application protocols and services.

IoT Design – I’ve been involved with microcontroller based hardware design since the early 1980’s with the 8748.  Recent work has been with the Raspberry Pi SBC and various Maker related microcontrollers (Arduino, Pico W, ESP32 and others).  Related technologies include MQTT, IoT security, Node-Red in addition to numerous sensor and motor solutions.
