Project details
You built an app with AI tools like Cursor, Lovable, v0, or Bolt — and now something feels off. Maybe it's slow, breaking under real use, or you're worried it isn't safe to launch with real users and real data. You're not alone: AI gets you to 80% fast, but the last 20% (security, architecture, reliability) is exactly where things quietly fall apart.
That's where I come in. I'm a full-stack engineer with 15+ years of experience, and I specialize in turning AI-generated projects into production-ready software you can actually trust. I find the hidden security gaps, fix the bugs that break in production, and restructure messy code so your app can grow without collapsing.
You get clear, honest communication in plain language — no heavy jargon, no surprises. Every issue I find comes with how serious it is and exactly what I'll do about it. My goal is simple: hand you back an app that's secure, stable, and ready for real users.

About Kaie
Full-Stack Web Expert | Scalable Systems and High-Performance Apps
Biguacu, Brazil - 5:04 am local time
Your product only gets one chance to make a first impression — and slow, buggy software ends careers. I'm a full-stack engineer with 15+ years turning messy requirements into systems that load fast, scale cleanly, and actually ship on time.
I've helped startups launch MVPs in weeks and helped growing companies rebuild architectures that were collapsing under their own success. I don't just write code — I ask why the feature exists, whether it's the right solution, and how we'll know it worked.
— What you get working with me —
Real ownership: I treat your project like it's mine. That means proactive communication, honest timelines, and no surprises at the finish line.
Business-aware engineering: I optimize for your KPIs — conversion rates, load times, user retention — not just clean code for its own sake.
Zero handoff chaos: Everything I build is documented, tested, and easy for your team to maintain after I'm done.
— Where I specialize —
Frontend: React, Next.js, TypeScript, Tailwind — pixel-precise UIs that score well on Core Web Vitals.
Backend: Node.js, Express, PostgreSQL, MongoDB — high-concurrency APIs and data pipelines that hold up under real traffic.
Cloud & DevOps: AWS, GCP, Azure, Vercel, Railway — automated deploys, solid monitoring, no 3am outage surprises.
Products: Admin dashboards, CRMs, SaaS platforms, custom portals.
— How I work —
Short async updates, no micromanagement needed. I scope clearly upfront, flag risks early, and ship incrementally so you're never in the dark.
