You will get audit debug and secure your ai built or vibe coded app
Project details
Did you build your app with Lovable, Bolt, Cursor, v0, or another AI coding tool? It ships fast, but AI-generated code often hides real problems: missing Supabase Row Level Security, broken auth flows, secrets exposed in client-side code, and Stripe integrations that quietly fail in production.
I'm a full-stack engineer with 8+ years of experience, including running engineering as a startup CTO, with deep hands-on work in Next.js, Supabase, and Stripe. I read through your codebase the way I'd review a teammate's pull request: line by line, checking what actually happens when a real user, or someone malicious, hits your app.
What I check: Supabase Row Level Security policies and auth rules, secrets or API keys exposed in the client, Stripe checkout/subscriptions/webhook reliability, core bugs affecting everyday use, and database schema or query issues.
Every order includes a clear written report of what I find. On Standard and Premium, I fix the issues myself and hand back a working, secured app, not just a list of problems.

About Vasilii
Full stack Software Engineer
Tbilisi, Georgia - 10:21 pm local time
Over the years I've built backend systems, databases, and APIs across a range of setups: REST and GraphQL APIs, microservices and distributed systems, cloud infrastructure, and containerized deployments (Docker). On the frontend, I work primarily with Next.js and Vercel. I also handle two areas that tend to break in production if done carelessly: payment systems (Stripe — Checkout, subscriptions, webhook handling) and database security (PostgreSQL/Supabase Row Level Security, multi-tenant data isolation). More recently I've been adding OpenAI/LLM integrations into existing products for teams adding AI features.
Recent example: I built and shipped a full SaaS application end-to-end — authentication, org-based RLS, Stripe subscriptions, gated features, deployed live — to demonstrate how these pieces fit together in one working product. Demo and source code are in my portfolio below.
Before Upwork, I co-founded and served as CTO at MySoft, leading architecture, technical strategy, and delivery for custom backend systems and infrastructure across multiple industries. I started programming in international ACM competitive programming olympiads, which is where the habit of writing precise, well-tested code came from.
Whether it's a backend API, a database/RLS issue, a broken Stripe integration, a Next.js deployment problem, or wiring an LLM into your product — send me the details and I'll tell you honestly whether I can help and how long it'll take.
