Exactlee Design & Development is a sole proprietorship built to help others bring products or companies to life. That can mean product development, prototyping, mechanical design, startup advice, or just an extra set of hands on a project. Anywhere I can't cover it myself, I've got a network to call on.

Who's Behind Exactlee

I'm Lee Wilkerson, with a B.S. in Mechanical Engineering, based in San Luis Obispo. Over the last fifteen years I've helped build a handful of businesses from the ground up, mixed in with stretches in more traditional settings like machine shops, medical device manufacturing, and aerospace. Startups don't leave room to hire in a specialist, so I learned to do most of it myself. On the technical side that meant facility layout, electrical, and production flows, speccing equipment or building it myself when it didn't exist. On the business side it meant fundraising and business development, whatever kept things moving. That range means I can usually find a way to help, whether you're still working out an idea or already running a business that just needs a hand in one specific area.

More about my background

Some brief credentials

01 / STARTUP

Founder · Product Startup

Space Campers — Camper Shells for the Cybertruck

Designed and built wedge campers and truck caps for the Tesla Cybertruck out of advanced composites, taking them from SolidWorks surfacing through CNC-cut molds and vacuum-infused parts to twenty delivered units. Two design patents and a set of utility patents, all granted, came out of it, along with a team-led press launch that landed millions of views in a week. The full site is preserved here as part of the portfolio.

Business Partner · Brewery Build-Out

Whalebird Kombucha — Facility & Fermentation

Helped build a kombucha brewery from a row of empty warehouses, with some great friends, and had a genuinely great time doing it. The equipment side covered the full industrial range: fermentation tanks, glycol chilling, CO2 distribution, refrigeration build-outs, keg and tank cleaning systems, and custom automated canning lines and depalletizers. Just as much of the experience was on the business side: raising money, hiring, and building a team that made the whole thing worth doing.

Lead Engineer · Bioreactor Design

WISErg — Grocery-Store Biodigesters

Designed biodigesters that took in food waste straight from a grocery store, weighed it, ground it, and processed it on-site, continuously monitoring pH and moisture to hold the ideal environment for breakdown, scrubbing the exhaust air of odor, and reporting everything back to the cloud so the store could track and reduce its own waste. I led multiple generations of that design, including the redesign that took the V2 unit from a $300k price tag down to $70k, the version that was actually built and delivered in numbers.

AI Integration & Training
  • Full AI integration built around your actual business: your files, workflows, and operations, not generic prompts
  • Hands-on training so your team gets meaningfully more output without adding headcount
  • Personal assistant setup: drafting, scheduling, document summarization, and project tracking running in the background
  • Automation of repetitive work: meeting notes, status reports, document generation, file organization, freeing up hours every week
  • Ongoing tuning as your workflows and use cases evolve, so the system keeps compounding rather than going stale

Website & App Development
  • Website design and development: years alongside designers and developers, now built AI-assisted myself, cutting cost and timeline
  • Setup built so changes are easy too: I can train you or your team to make edits yourselves using AI tools, no developer required for day-to-day updates, and no monthly fees
  • Custom domain and business email setup, configuration, and mail forwarding
  • DMARC, SPF, and DKIM configuration so your email actually lands in inboxes instead of spam

Product Design & CAD
  • Product design and development: concept through production-ready
  • 3D modeling in SolidWorks: surfacing, complex geometry, large assemblies
  • Design for manufacturability: so it can actually be made at a price that works
  • Reverse engineering and 3D scanning
  • Basic stress and load analysis (SolidWorks Simulation), for design reference only, not a substitute for a PE-stamped structural analysis

  • Product animations: exploded views and walkthroughs (see example)
  • Marketing-ready imagery for launch pages, ad creative, and investor decks

Product Development & Prototyping
  • Concept to working prototype: taking a sketch or CAD model and making something you can hold, test, and put in front of people
  • Built through multiple rounds of iteration, starting cheap and rough and refining toward something manufacturable, each version answering a specific question before the next gets built
  • Low-cost proof-of-concept methods (3D printing, off-the-shelf and sourced parts, hand fabrication) and functional testing for fit, mechanism, load, and real-world use
  • A bootstrapped approach: years of building startups on no budget, so the instinct is always proving what needs proving before spending on what doesn't

  • Suggested assembly instructions, written so a shop that's never seen the part before can build it correctly the first time
  • RFQ-ready documentation, put together so a vendor can quote it without a lot of back and forth (sometimes called a Technical Data Package, or TDP, in aerospace and defense procurement)
  • See it in action: a complete 21-page RFQ and assembly package, built for a real production run

A note on scope: I'm a degreed mechanical engineer, not a licensed Professional Engineer. Work requiring a PE stamp — structural calculations for permits, certified analyses, code-compliance sign-off — is outside what I offer, and I'll tell you so and point you to the right person.
