Project details
Need a landing page that loads instantly and actually converts — not a slow, templated page?
I design and build fast, modern landing pages with Next.js + Tailwind CSS: clean responsive design, smooth on mobile, SEO-ready, and optimized for speed (great Core Web Vitals). Whether it's a product launch, startup, app, or service, I'll turn your idea into a polished page that looks premium and drives action.
What you get:
• A custom, responsive landing page (no cookie-cutter template)
• Fast load + SEO basics (meta, Open Graph, semantic markup)
• Contact / lead form, CTAs, and the sections you need
• Deployed live and easy for you to update
I'm a full-stack developer who's built and launched real production apps. Tell me about your product and I'll recommend the best structure to convert your visitors.

About Phisit
AI Developer & LLM Security | RAG, Agents, Python/Next.js
Mueang Nonthaburi, Thailand - 5:37 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.
