ENGINEERING & CONSTRUCTION / PRODUCT ARCHITECTURE
Cumulus
I entered engineering and construction without prior experience. Working directly with users, I learned their workflows and turned what I learned into practical digital tools.
Role
Partner and Founding Product Architect
Engagement
MCW client engagement / HVAC equipment-selection concept
MCW / CLIENT ENGAGEMENT
MCW internal operations tool
MCW, a mechanical engineering consultancy, hired Cumulus to build an internal tool for its staff.
PROJECT FOCUS
I led the user experience of the project, helping address communication and transparency issues by making ongoing work and next steps easier to track.
THE TOOL BROUGHT TOGETHER:
01
CRM
Company, contact, and project information, Vacations
02
Projects
Deadlines and peer reviews
03
Staff tasks
Assignees, statuses, hours, and due dates
04
Equipment tracking
Submissions and review (beta)
USER TESTING / BUILDING
Tested early workflows with staff and used their feedback to shape the tool. I also learned Softr and Airtable while helping build it.
CLIENT OUTCOME
MCW now uses the tool across its offices
The tool helped address communication and transparency issues and made it easier for staff to move work along.
EQUIPMENT-SELECTION PLATFORM
Cumulus concept: equipment selection
Separately, I helped develop a concept for an HVAC and domestic hot water (DHW) equipment-selection platform. It was intended to help engineering teams organize technical information, compare equipment, and coordinate vendor submissions.
My contribution
I contributed to product direction, workflows, requirements, information structure, interface design in Figma, and the vendor-submission process. I also worked with Airtable and Softr.




STATUS
Concept stage only
The platform remained at concept stage because funding was limited. It was not launched.
