I Want a Code Review Before Launching My AI-Built App
You've built an app using AI tools and it seems to work, but you're not confident it's ready for real users. You want someone who actually knows code to review it, find potential issues, and tell you if it's safe to launch.
Common Causes
- AI-generated code often has subtle bugs that only appear under real-world conditions
- Security vulnerabilities are common — exposed API keys, no input validation, missing auth checks
- Performance issues that don't show up until you have real traffic
- No error handling — the app works on the happy path but crashes on edge cases
- Database schema issues that will cause problems as data grows
How to Fix It
- Post a code review task on humansfix.ai — a developer will review your entire codebase
- They'll check for security issues, performance problems, and common bugs
- You'll receive a report of findings with priority levels
- Critical issues can be fixed as part of the same task or as follow-up tasks
- A code review typically takes 1-2 days and gives you confidence to launch
Real developers can help you.

I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.
