I will build your mvp or web app with claude code and a spec first workflow
Long Trinh
About this gig
AI-generated code has a reputation: fast demos, broken products. My workflow exists to fix that.
I shipped a production hotel management system where AI agents wrote most of the code - under a strict spec-and-verify discipline. Full case study at longtrinh.com/capyinn.
WHAT I BUILD
* MVPs: web apps with auth, payments, dashboards (Next.js/TypeScript)
* Features and fixes in your existing codebase
* AI features: chat, RAG, agents, Claude/OpenAI integrations
HOW WE WORK (this protects both of us)
1) You describe what you want in plain words
2) I write a short spec: exactly what will be built and what "done" means
3) You approve it - then I build with tests, verifying each step
4) Delivery: working software + walkthrough video + docs
Changes outside the approved spec become a new order - so the price you see is the price you pay.
WHY ME
* Production proof, not a portfolio of demos
* You own 100% of the code
* Clear English communication, fast responses
Message me before ordering - bring your idea, and I will tell you honestly what fits your budget.

I am an Automated Content Systems Specialist and Media Architect. I design and operate end-to-end automated pipelines that handle deep data-driven research, investigative reporting, scriptwriting, and high-retention video production for high-engagement niches—specifically True Crime, Finance, Economics, and Social Commentary. By orchestrating advanced AI workflows, I transform complex data into algorithm-optimized video assets for TikTok, Reels, and YouTube Shorts at scale. I help media brands and faceless channel operators dominate high-CPM niches with speed and consistency.

FAQ
Who owns the code?
You do, 100%, on delivery. It lives in your repo (or I hand over a clean repo), with no license strings attached. NDA available on request.
Isn't AI-written code low quality?
Unsupervised, yes. That is why every order starts with a written spec, is built test-first, and is verified step by step before delivery. The hotel system in my case study has run in production this way.
What tech stack do you use?
Default: Next.js + TypeScript, Postgres/SQLite, deployed on Vercel or a VPS. Different stack? Message me first - if I am not the right fit, I will say so before you pay.
What counts as "one feature" in the Basic package?
One user-visible behavior with clear done-criteria - e.g. "CSV export for the orders table" or "password reset flow". If your request is bigger, I will tell you in the spec before you commit.
Can you work in my existing codebase?
Yes, that is what Basic is for. I need repo access (read is enough to quote), and the spec will state exactly which files change.
