Joe DeMarco

AI-assisted product prototyper who turns ambiguous customer needs and early market hypotheses into functioning applications, MVPs, automations, and experiments. Combines 10+ years of engineering experience with rapid, prompt-driven development to clarify workflows, define product scope, assemble full-stack solutions, test assumptions, and iterate from real feedback. Especially effective in 0-to-1 environments where the problem is not yet fully defined.

AI-Assisted Product Prototyper & MVP Builder at Independent / Freelance (2024-05 – Present)

Translate loosely defined customer problems and market ideas into concrete workflows, product requirements, working prototypes, and testable MVPs. Use Cursor and generative AI as implementation partners to rapidly assemble and iterate on web applications, automations, integrations, data models, and user interfaces while applying engineering judgment to scope, behavior, testing, and reliability.

Take concepts through the full experimentation loop: identify the riskiest assumption, build the smallest useful product, create landing pages and outreach campaigns, collect feedback, and revise the product direction. Prototyped multi-tenant SaaS, AI assistants, voice experiences, operational dashboards, document/PDF workflows, customer-intake systems, lead-generation sites, and internal automation tools. Work across product, engineering, and go-to-market concerns, making pragmatic tradeoffs to get a usable solution in front of customers quickly rather than waiting for perfect requirements.

Software Engineer at Lockheed Martin, Space Systems Company (2016-09 – 2024-05)

Developed C/C++ software for the Jupiter satellite communications ground system supporting 4G LTE voice, data, and fax services. Implemented SNOW 3G and AES ciphering, TFO voice-quality enhancement, RoHC header compression, shared software APIs, and component-test infrastructure.

Built

Python test automation and C unit tests for ciphering, TFO, RoHC, and DTMF; maintained Git repositories and formal release documentation. Co-led the DSP team and contributed to design reviews, planning, resource allocation, and formal software releases.

Production Support Engineer at Advent Design Corporation (2015-08 – 2016-09)

Managed inventory and time-tracking databases using Microsoft Access, VBA, and SQL; prototyped Windows (Python/Qt) and Android (Java) applications for manufacturing operations.

CAD Technology Manager / Draftsman II at Richard C. Mast Associates (2004-06 – 2015-08)

Produced civil engineering and survey plan sets, designed storm and sanitary sewer systems, automated workflows with AutoLISP, and led the company transition to Civil 3D standards and styles.

Bachelor of Science in Electrical Engineering – Temple University, College of Engineering (2015-12)

Associate Degree in Engineering Science – Montgomery County Community College (2013-05)
