I'm a grant writer who specializes in SBIR and STTR proposal, the federal, non-dilutive R&D funding that lets startups, inventors, and deep-tech founders commercialize their technology without giving up equity. I've written for NIH, NSF, and DoD/Navy solicitations. Top Rated, 100% Job Success, 5.0 across every engagement. Most of my clients have the hard part already solved: real technology, real data, a genuine breakthrough. What stands between them and the funding is a proposal that has to do two things at once satisfy strict federal compliance rules to the letter, and make a technical innovation legible and compelling to evaluators who may not share the founder's expertise. That's the gap I close. What I do: - SBIR/STTR Phase I proposals — technical volume authoring, cost volume construction, and budget structuring that stays within agency caps (including Base/Option splits where required). - Federal submission compliance — formatting, page and font limits, and multi-volume requirements verified against official agency instructions (DoD DSIP, Grants.gov, and agency-specific portals). - Technical writing & consultation — turning complex science and software into clear, evaluator-ready narratives. Recent work includes documentation and consultation for AI software, plus invention and patent-stage application writing. Recent highlight: I led a complete Navy SBIR Phase I submission for a GPS-denied timing-correction software technology, authoring the technical and cost volumes, engineering the Base/Option budget within Navy caps, bringing all seven required DSIP volumes to 100% compliance, and supporting the client through certification and on-time submission under real deadline pressure. The client endorsed the work as committed to quality, accountable for outcomes, and detail-oriented. How I work: I start with the solicitation and its evaluation criteria, flag eligibility or compliance disqualifiers before they cost you, then build a submission-ready package narrative, budget, and attachments with a clear checklist so nothing slips before the deadline. If you have an SBIR/STTR or federal R&D opportunity coming up, message me with the solicitation number and the due date. I'll give you an honest read on fit and exactly how I'd approach it.
