You will get a live, full-stack app with Stripe payments, ready to charge customers
Rising Talent
Project details
You'll get a real, working product your customers can sign up for and actually pay for - built, deployed, and live - not a prototype that sits in a folder.
I build the whole thing end to end, solo: front-end, back-end, database, secure auth, and real Stripe payments wired in and tested with live money. One core flow, fixed scope, fixed price - so you know exactly what you're getting and exactly what it costs.
I've already shipped a subscription app to the Apple App Store, Google Play, and the web that takes real payments today. I'll build yours the same way - and you own the code, accounts, and keys at the end, so you're free to grow it without me.

About Kevin
AI Automation & Agent Builder | Full-Stack Apps That Ship Live
Santa Ana, United States - 8:58 am local time
Most freelancers prove one thing. Here's what I've actually shipped:
- A live subscription app on the Apple App Store, Google Play, and the web, processing real Stripe payments today. Solo - architecture, payments, native mobile release, and the growth funnel around it. The hardest, most-faked milestone in software, done alone.
- A production autonomous AI/ML decision platform that has run unattended for over six months and counting: ~35 analysis modules across 7 stages, a dual-engine consensus design that hard-blocks when its rules engine and ML ensemble disagree, an LLM review gate that fails CLOSED on any timeout or error (never auto-approves), and a daily model retrain with automatic rollback on regression. Real safety engineering, not a demo.
- A persistent-memory AI assistant system I run in daily production across multiple businesses - hybrid vector + full-text + knowledge-graph retrieval, automatic capture, self-healing, and backups. It compounds context instead of forgetting it, which is exactly where most stateless RAG bots fall down.
- A live paid-acquisition engine delivering qualified leads at around $15-20 each, well under the typical market rate. I don't just build the product - I bring it customers and prove the cost per result with real numbers.
What ties it together: I can build the thing AND get it used. AI systems and full-stack apps are the engine; automation and growth are how the engine produces results.
Background: B.A. Accounting (Cal State Fullerton) and a finance career before this, so I build like an owner - unit economics, margins, and ROI baked into every decision, which matters when there's real money on the line (payments, ad budgets, deployments that have to be right).
If you need one builder who can own a hard system end to end - AI, app, automation, or the growth around it - and actually finish, let's talk. Tell me the outcome you need and I'll tell you exactly how I'd build it.
Steps for completing your project
After purchasing the project, send requirements so Kevin can start the project.
Delivery time starts when Kevin receives requirements from you.
Kevin works on your project following the steps below.
Revisions may occur after the delivery date.
Define the one core flow
We pin down the single most important thing your app must do, who it's for, and what done looks like - so we build the right thing fast, with no scope creep.
Build front-end, back-end & auth
I build the UI, the database, and secure signup/login, then wire your core feature end to end on a clean, mobile-friendly foundation.
