Full-Stack & Mobile App Developer · Cartersville, GA

Shipped real products solo. Ready to build yours.

Self-taught developer who designed and shipped two production SaaS platforms end to end — web, native iOS/Android, AI, and billing through app store submission — plus a free multi-system companion hub still shipping daily. Thirty years running high-volume kitchens before that, which is where the discipline to actually finish things comes from.

What's been built

KeyMacro.fit

AI-powered nutrition & training platform

An AI nutrition and training partner that turns your goals into a personalized meal plan, logs meals from a photo, and coaches you through the day — designed and built solo, from database to App Store.

Free

Stay in the zone.

Hit somewhere between 90–110% of your target and you're golden. No gram-by-gram panic, no red numbers — just a band that forgives a normal day.

KeyMacro dashboard — Green Zone calorie ring and daily macros
Free

Snap it. See it. Log it.

Point your camera at a plate and KeyMacro breaks down what's actually on it — protein, rice, broccoli, all editable before you log. No typing, no guessing.

KeyMacro Smarter Snap — plate scan with detected foods and macros
Strategist

A coach, not a guilt trip.

Slip up on a Tuesday? Coach Key doesn't lecture — it quietly rebalances the rest of your week. Chat, photo check-ins, real adjustments. Calm through structure.

KeyMacro Coach Key — AI nutrition coaching chat
Free

Your macros know it's leg day.

Train in the same app you eat in. The Strategist's SmartFit shifts your targets to match today's session — more carbs before legs, no spreadsheet required.

KeyMacro Workout — SmartFit macro adjustments for training day
Free

A score for showing up.

Not a medical score. Not a streak you can break with one bad day. Just a daily 0–100 read on the habits that actually move the needle — nutrition, training, hydration, engagement.

AI-powered social media content platform

A platform that generates social media content — video, images, and voiceover — and publishes it directly to YouTube, TikTok, and Instagram, built solo from AI integration through app store submission.

Editor

Slides that speak.

Build carousel slides with AI voiceover baked in — write once, hear it back, ship a scroll-stopping post without bouncing between tools.

SlidePress — carousel slide editor with AI voiceover
AI

From idea to campaign.

Start with a topic and let Gemini draft the angle, structure, and copy — then edit what you want before it ever hits a timeline.

SlidePress — AI topic and content generation
Export

Carousel or video — your call.

Export the finished piece as a carousel or a video cut, ready for the platforms you actually post on.

SlidePress — export carousel and video
Publish

Post everywhere.

Publish straight to YouTube, TikTok, and Instagram through first-party OAuth — no middleman export dance.

Campaign

Check it off. Keep your place.

Campaign leveling for PoE 1 and 2 as interactive checklists — zone grouping, class-relevant rewards, boss callouts — so a wiki tab doesn't erase where you left off.

03

Small web apps

Booking systems, ordering tools, simple dashboards — custom-built for how your business runs.

04

iOS & Android apps

Native-feeling mobile apps for iOS and Android from a single codebase — built and shipped twice already.

05

Automations

Connect the tools you already use — booking alerts, CRM sync, webhook workflows, and repetitive tasks handled without manual work.

About

From the kitchen to the keyboard

For 30+ years I ran high-volume kitchens — managing teams of 6 to 10, controlling costs, negotiating with vendors, and keeping quality consistent under real pressure, night after night.

That job teaches you something you can't fake: how to actually finish things when it matters, not just plan them.

I taught myself to build software and applied that same discipline to it. Over the past stretch I designed and shipped two full production SaaS platforms on my own — web apps, native iOS/Android apps, AI integrations, payment systems, and marketing sites — through to app store submission, plus a free multi-system companion hub that's still shipping.

I'm not new to being responsible for something real. I'm new to doing it in this domain — and I'm ready to keep building.

A.A., Media & Web Design (Full Sail University), plus two years of Computer Science coursework (Florida Atlantic University).

Transferable Leadership Experience

30+ years leading teams of 6–10 in high-volume, high-pressure operations (kitchen management, hospitality). Vendor negotiation, cost/budget control, process optimization, training and mentoring, and maintaining quality under pressure — the same discipline now applied to shipping software independently.

Education

A.A., Media & Web Design (Full Sail University), plus two years of Computer Science coursework (Florida Atlantic University).
