About Us

Our ApproachAerial_View

InterSpace Systems is proud to be part of the emerging commercial space industry (Google Loon, DJI, StratoStar, etc..). Large Aerospace companies have worked with national governments to invoke large scale space ventures which have been historically high cost, highly reliable, state of art programs.

While these programs are essential to national interests, agile companies like InterSpace Systems can utilize off-the-shelf components and couple them with engineering expertise to provide architectures with “niche” capabilities at significantly lower development time and price. Our systems and services have provided rapid engineering evaluation and analysis to customers within the biotech, rocket and aerospace industries. 

We also strive to provide situation awareness to local municipalities during times of immediate need.

Our Story

InterSpace Systems is a group of engineers culminating over 50 years of experience with advanced manufacturing, airfoil design, unmanned systems, development of high pressure liquid rocket motors and gas turbine turbo-machinery.

Our goal is to provide engineering solutions that prioritize customer goals, milestones, and values.  Focusing on new technology, InterSpace Systems is driving towards blockchain technology applications and updating inefficient non-verifiable systems with the invention of blockchain consensus mechanisms. 

Joel L. Perez P.E.


Founder & CEO

Joel has over 16 years of experience in research, development, and design of rocket engines, turbomachinery and combustion systems.  He is fluent in precision aerospace design, development test & analysis, additive manufacturing, and holds a M.S. Graduate degree in Astronautical Engineering from USC and a B.S. in Aerospace Engineering from UCSD.  Joel formulated InterSpace Systems to provide consultation, rapid design, development, and analysis of customer products, unmanned systems, and system architectures. Joel is licensed as a California Professional Engineer, FAA Single Engine Instrument Pilot, Commercial UAS Remote Pilot, and was recently inducted as an Associate Fellow into the American Institute of Aeronautics and Astronautics (AIAA) for his contributions in the aerospace & astronautics fields.

Ben Fishler E.I.T

Engineering Analysis (CFD), Design, Manufacturability and Process Automation

With a B.S. in Mechanical Engineering, M.S. in Aerospace Engineering from UCSD, Ben has over 14 years of experience spanning process optimization, manufacturing, mechanical and aerodynamic design, CFD and FEA analysis. Past projects include turbomachinery rotating components , fuel and oil systems, fusion energy research and design. He is the creator and inventor of the STRUdittle, a precise low cost filament extruder which ships worldwide. He has been awarded seven patents, two publications, and is a certified private pilot. His innovated designs are also being featured for optimized low cost architectural design and eco-homebuilding.
