You will get build a full-stack web app or MVP — accounts, database, payments
Rising Talent

Project details
Have an idea for a web app but need someone who can actually ship it — end to end?
I build production-ready web apps and MVPs: user accounts, database, the core features that make your product work, payments, an admin dashboard, and deployment — all in clean, maintainable code. Not a prototype that falls over; a real product you can put in front of users.
What you get:
• A working, deployed web app (not a mockup)
• Auth, database, and your core features
• Payments & admin dashboard (higher tiers)
• Responsive, fast, and built to grow
I built and launched a full content platform solo (accounts, payments, admin, mobile app) — I ship complete products fast. Tell me your idea and I'll map the leanest MVP to get it live.
Stack: Next.js, TypeScript, PostgreSQL/Prisma, deployed on Vercel.

About Phisit
AI Developer & LLM Security | RAG, Agents, Python/Next.js
Mueang Nonthaburi, Thailand - 7:37 am local time
Most developers can wire up a chatbot. Few can also tell you how it leaks
data, obeys a hidden instruction buried in a document, or hands one user
another user's answer. I do both.
WHAT I BUILD (Python / FastAPI and TypeScript / Next.js):
- LedgerLens - an AI bookkeeping tool with a self-audit engine that flags
fraud and anomalies. Deterministic pandas core + Claude, 33 automated tests.
- DocChat - a RAG agent that answers questions about any webpage with
grounded, cited answers.
- INKVERSE - a full content platform I built and launched solo in ~2 weeks:
authentication, PromptPay payments, an Android app, and an anti-scraping
reader. I then drove 100,000+ views to it.
HOW I SECURE AI APPS:
I red-team LLM applications against the OWASP LLM Top 10 - prompt injection
(direct and indirect), data leakage, and jailbreaks - and I write the fixes,
not just the report. Open-source tools I built:
- promptraid - an LLM prompt-injection red-team toolkit with canary-confirmed
probes across the OWASP LLM Top 10.
- raidkit - an authorized, non-destructive web vulnerability scanner.
- secure-api - a hardened FastAPI backend with a full test suite.
I found and patched a real indirect prompt-injection hole in my own RAG app,
then re-tested until it held.
If you are shipping an AI feature and want it built right, or you already have
one and want someone to try to break it before an attacker does, that is my
lane. I also take on straight full-stack and payment-integration work
(Next.js, FastAPI, Stripe / PromptPay).
I communicate clearly, work async across US, EU, and Asia hours, and I do not
disappear after delivery. Available to start now.
