Project details
According to Upwork policies, I am not allowed to share any info (e.g. email) w/o a contract.
This project exists for all the clients that need me to dive into the source code, but without a big contract.
It's more for you if you are unsure about cooperating with me on the contract and would like additional context w/o spending the budget.
I will spend 1h and share my feedback

Frontend Architect for Technical Interviews
Vitalii is a strong technical interviewer who consistently creates a comfortable, professional environment for candidates. His question bank is well-chosen, technically accurate, and relevant to the role. He pushes back thoughtfully when needed and engages candidates as peers rather than just testing them on theory. Across all interviews he remained consistent, warm, and fair throughout. Would happily work with him again.

Senior Angular Developer with solid experience in TypeScript, Firebase and architecture
Vitalii helped us resolve several issues with our Angular-based quiz game, and the experience was excellent from start to finish. He is professional, dependable, and solution-focused, taking full responsibility for results rather than simply completing tasks. His attention to detail was especially evident during our work with RxJS and Firebase. If you're a founder or business owner seeking a reliable and skilled software developer, I highly recommend Vitalii.

Prescription form embedded via iFrame
Was an absolute pleasure working with Vitalii. We needed a very niche feature built for our system and it was one of those cases where AI or vibe coding wouldn’t help. So I needed to seek out help from an expert and Vitalii was the perfect fit. Highly recommend!

⭐⭐⭐⭐⭐ "Vitalii is a person to cooperate with for those who care about their time, money, quality of work, deadlines, and want to avoid hustling. I was impressed by his ability to dive into the context of tasks, finding the right approach for a particular task, asking the right questions, and providing updates on a daily basis. Everything went smooth from the very first message to the final result. We were able to rump up the developing process, improve the code base without the need for big rewrites, and all within just a week with Vitalii's help. His architecture skills and experience have helped us to find the right way for developing the last milestone which was quite tricky and complicated." - Daniel Turczański, Entrepreneur, JQL Search Extensions.
