You will get your vibe-coded React/Next.js project audited (Lovable/Cursor/Base66/etc)
Project details
You want to prepare your vibe-coded project for production and make sure it's rock solid. I 'll review the code quality, performance and security, and provide a clear list of all identified issues.
With over 18 years of development experience, I have a trained eye for common and critical issues. I also actively use vibe-coding tools myself, so I understand their strengths and, more importantly, their flaws.
I focus on React and Next.js projects - this is the stack I'm good at.
Optionally, I can also fix the discovered issues if you purchase the add-on.

About Konstantin
Senior Full-Stack Developer | TypeScript, React, Next.js | AI-First
Novi Sad, Serbia - 3:19 pm local time
I’m a good fit if you want to:
- Launch an MVP or new product feature quickly
- Stabilize or refactor an existing React/Next.js app
- Add AI capabilities (chat, voice, research, automation) to your product
Before writing a line of code, I:
- Ask questions to understand your business goals and constraints
- Suggest technical options with clear pros/cons in plain English
- Propose a simple plan (scope, milestones, risks) so you always know what's happening
Recent work:
- Launched PreVibe (AI market research) - full stack + MCP server, zero to production
- Built Dictate Button - shipped as Web Component + React library on npm + WebSocket API
- Developed biotech social platform - handled everything from GraphQL API to TailwindCSS UI
Stack: React, Next.js, TypeScript, Node.js, Supabase, Firebase, Vercel, plus AI SDKs (OpenAI, Deepgram, Vercel AI SDK, Genkit)
I also handle technical decisions, documentation, server configuration, and CI/CD, so you can focus on customers, sales, and fundraising.
If you’re not sure what to build or which stack to choose, you can start with a 30‑minute consultation to clarify your options and get a technical roadmap.
