Andrei Chenchik, iOS Software Engineer

I have 4 years of experience as a mobile engineer and over 7 years as a product lead. I progressed from support specialist to frontend dev, then to product lead, and finally to Swift development, plus some TypeScript for backend, with each step deepening my industry synergy.

As a generalist, I believe every solution involves trade-offs, and a broad perspective is essential for evaluating options and finding the best approach. Mentoring others also enhances my own understanding.
