Top Rated
Project details
I’ll help you fix, stabilize, and finalize your SaaS or AI project so it’s truly production-ready. This is for cases where your product is already 80–90% built, but backend issues, integrations, authentication, or deployment problems prevent you from launching and getting real users.
❗❗❗ 𝐃𝐎𝐍’𝐓 𝐁𝐔𝐘 𝐓𝐇𝐄 𝐏𝐑𝐎𝐉𝐄𝐂𝐓 - 𝐌𝐄𝐒𝐒𝐀𝐆𝐄 𝐌𝐄 𝐅𝐈𝐑𝐒𝐓
Before starting, I'll review your codebase to identify what's broken, missing, or unstable. The catalog price is a starting point - your final quote will depend on the amount of work required after the code review and the agreed scope.
What you get:
✔ Bug fixing & debugging
✔ Backend/API stabilization
✔ Frontend fixes
✔ Integration fixes (Stripe, APIs, auth, etc.)
✔ Performance improvements
✔ Deployment fixes
✔ Production-ready release
Not included:
✖ Full product development from scratch
✖ Large new feature builds
✖ Full system redesign
✖ Enterprise architecture rebuilds
If needed, we can split complex work into phases.
How we work:
💬 Free consultation → 📋 You share repo/project → 🔍 Code review → 📐 Fix plan & estimate → 💻 Iterative fixes → 🚀 Launch-ready system
Send me a message and let's discuss your project.

Senior Full Stack Developer for SaaS Platform in Logistics & Transportation
Pavlo was great to work with. He understood our business much faster than we expected, which saved us a lot of time explaining every little detail. The project had a lot of moving parts - React frontend, Node.js backend, APIs, dashboards - and he was comfortable with all of it.
Whenever we got stuck, he usually came back with two or three possible solutions instead of just pointing out the problem.
Communication was easy, responses were quick, and we always knew what was happening. We also appreciated that he challenged some of our ideas and suggested better approaches. We'd definitely work with him again.
