You will get a working, clickable app prototype built and verified in one week
Project details
You will get a fully working, tested application feature — not just code, a real deliverable. I follow a locked process: Spec, Build, Verify, Ship, so scope and timeline are confirmed before any development starts. Every deliverable is tested for real-world use, not just checked to compile. Choose Starter for a working prototype, Standard for a full MVP build, or Advanced for design and development combined. Ideal for founders and small teams who need a working product without hiring a full dev team.

About Terrell
"Full-Stack App Developer | AI-Directed Build | MVP's & Marketplaces
Upper Marlboro, United States - 8:57 am local time
Proof of work: Penthouse Thrift, a two-sided resale marketplace I designed and built from the ground up as founder — not a tutorial project, a live, functioning platform with:
Real payment processing — Stripe integration handling actual transactions, with escrow-based fund holding until delivery confirmation
Automated shipping & logistics — Shippo integration that generates shipping labels automatically the moment payment confirms, with retry logic for failures.
Custom marketplace architecture — built and fixed a real data-sync system connecting seller listings to the live storefront, the kind of backend logic most "no-code" builds never touch.
Role-based access & security design — a permission system built specifically so sensitive features stay genuinely hidden (not just visually locked) from unauthorized users.
End-to-end business thinking — I don't just build the app; I model unit economics, customer acquisition cost, and competitive positioning, so what gets built actually makes business sense.
What I bring to a project:
Fast, iterative building — I can go from concept to working prototype in days, not months
Real debugging discipline — I trace problems to their actual root cause instead of patching symptoms
Business judgment alongside technical execution — I think about margins, security, and scalability, not just "does it look right"
Clear communication — I document decisions and reasoning, so you always know what was built and why
I'm a strong fit if you need:
A marketplace, CRM, or business platform built quickly without a full dev team
Someone who can architect the system, not just follow a spec
Payment/shipping/logistics integration done correctly the first time
A builder who treats your business goals as part of the job, not separate from it
