He has worked as a systems architect, trainer, content author, and software developer in addition to helping manage the company.

Maurice has worked in the aerospace and software industry his entire professional career. After graduate school, Maurice moved to Seattle, WA to work for Boeing’s Commercial Airplane division. While working at Boeing, Maurice helped maintain applications built on Fortran 77 and proprietary software critical to the community noise and flight operations groups. After working with the engineering teams at Boeing, Maurice decided to focus on software development for business systems. He spent nearly 7 years working at Microsoft developing and maintaining a variety of testing harness tools and applications as member of the Office team. After leaving Microsoft, Maurice worked as a consultant, helping customers design and implement business critical applications (web applications, databases, and services).

Maurice has been an integral part in the development of the MONSID API and toolset (written in C#, C++, C for both Windows and Linux platforms), which began in 2016. He has led the successful delivery of software for a variety of NASA JPL fault management projects. He also works with messaging frameworks such as ROS and cFS.

Ksenia Kolcio

Vice President, Okean Solutions, Inc.

Ksenia Kolcio is the Vice President and co-founder of Okean Solutions, Inc., where she leads the aerospace systems business activities. She has been PI and supported several Phase I, II, III, and BAA programs for NASA and AFRL.

Focus areas include spacecraft fault management and GN&C technologies and analysis tools. Ksenia has successfully proposed, negotiated and executed Phase I, II, and III contracts with the AFRL and NASA to develop fault management for responsive spacecraft. She also collaborated with other small businesses on NASA Phase II/III programs to develop x-ray based navigation technologies (XNAV) and user interface and measurement models for navigation mission prototyping tools (GSFC ODTBX).

Prior to forming Okean Solutions, Ksenia was employed at Microcosm, Inc. as a Senior Systems/GN&C Engineer. There she provided algorithm development, simulation/analysis, SBIR program technical lead/management, as well as hardware and software development support. Projects included miniaturized three-axis attitude and navigation sensor solutions, Lunar gravity sensor concept, control simulation for free-floating space telescope mirrors.

Ksenia started her career at Northrop Grumman Space Technology (NGST) in the Avionics Systems Center. She was the lead autonomy and fault management engineer for two classified programs responsible for the FM architecture design and requirements flow down and traceability. On the NPOES program she developed flight vehicle simulator architecture for operator training and procedure checkout. She was also testbed lead engineer on the AEHF Gimbal Control Subsystem responsible for the design, build-up, integration of the testbed simulator and test harness, resulting in successful on-time verification. At the beginning of her career at NGST, Ksenia was a control system engineer for internal research and development projects, such as the optical intersatellite link program and the autonomous onboard processing initiative where she worked on applying a model-based FM system to spacecraft GN&C systems.
