Developer | Full Stack Developer for Performance Optimization (React, Node.js, API)
⭐⭐⭐⭐⭐
Working with Mykola has been one of the best development experiences I've had. He's the lead developer behind NewtonOS, our internal ERP and operations platform, and he's consistently delivered complex features at a level I'd expect from a much larger team.
He has a rare combination of strong technical skills (React, TypeScript, Vite, Clerk, integrations with multiple WMS/TMS systems) and real product sense — he understands the business logic behind what he's building, not just the code. When I bring him a half-formed idea, he comes back with thoughtful questions and a clean implementation plan rather than just executing blindly.
What I appreciate most:
- **Reliability** - deadlines are met, communication is clear, and he proactively flags issues before they become problems.
- **Code quality** - clean, maintainable, and well-architected. He thinks about edge cases and long-term scalability.
- **Ownership** - he treats the product like it's his own, which is exactly what you want in a long-term developer.
- **Flexibility** - handles everything from architectural decisions to detailed CSS work without complaint.
If you're considering hiring Mykola, don't hesitate. He's the kind of developer you build a company around. Highly recommended.

Complete & Fix Existing Full-Stack Platform (Node.js / React / Stripe / Twilio / AWS)
I am requesting return of the remaining escrow funds because the current milestone was not completed correctly and was never approved for payment.
After the milestone submission, multiple revisions and implementation issues were identified involving the functionality and overall completion of the phase deliverables. The project remained in revision status because the work was not fully completed or properly finalized for this phase, which is also reflected within the message history and revision discussions.
The conversation history shows acknowledgment that the milestone still needed additional fixes, updates, and corrections before it could be considered complete. Because the work for this phase remained unresolved and unfinished, I chose not to continue the contract or approve release of the escrow payment.
Since the milestone was never properly completed, finalized, or approved, I am requesting that the remaining escrow funds be returned rather than released.
