Senior Frontend Developer (React). Rebuild & Production-Ready SaaS UI (Figma-based)
Mykhailo did an excellent job on the Revyr frontend. He implemented features accurately, was responsive to feedback, paid attention to UI/UX details, and consistently delivered clean, production-ready work. Communication was professional throughout the project, and he was proactive in resolving issues and refining the product. I would be happy to work with him again on future frontend development.

Full-Stack Developer for Web App MVP (React, TypeScript, Supabase)
Working with Mykhailo was a great experience from start to finish. Communication was always smooth with regular updates. The final app turned out clean, polished, and exactly what I had in mind. He delivered on time and with a high quality of work. I'd hire him again in a heartbeat. Highly recommended!

🔥 HOW I WORK
I think like a product engineer, not a code-monkey. Before writing a line, I align on the business outcome — who the user is, what they pay for, where the product needs to be in 6 months. Then I ship in weekly demos and stay available on Slack / Telegram for fast turnaround.
Typical cycle:
1️⃣ Discovery & scoping (2–3 days) — define MVP boundary
2️⃣ Architecture — clean foundations, scalable schema, right stack
3️⃣ Weekly sprints with demos — progress every week
4️⃣ Production launch — CI/CD, monitoring, error tracking
5️⃣ Post-launch support — most clients keep me on
