Strong interfaces and structured frontend systems
I design and implement interfaces where performance, UX quality, state structure and careful attention to detail all matter.
Fullstack developer
Hi, I am Pavel Frolov, a fullstack developer.
My background is rooted in frontend engineering, but today I work as a fullstack developer: I build interfaces, take on backend work and ship my own products end to end when needed.

About
Engineering approach and product experience
I am a fullstack developer with more than 7 years of experience. Frontend was my core specialization for a long time, but over the years I expanded into backend work, using it actively in my own projects and taking on related tasks in my professional work as well.
My background includes web applications, cross-platform mobile products and desktop software. I work with React, Next.js, TypeScript, React Native, Capacitor, Electron, Node.js and the supporting tooling required to ship complete products rather than isolated parts.
I prefer a professional and restrained way of working: understand the context, avoid unnecessary complexity, keep quality high and move the product forward with clarity.
Expertise
What I do best
Fullstack product execution
I can handle not only the client side, but also backend logic, integrations, data and technical infrastructure for both personal and professional products.
Cross-platform thinking
Practical experience across web, mobile and desktop helps me make broader decisions and build more coherent products.
Experience

Approach
What matters to me in product work
Engineering clarity
I prefer solutions that are maintainable, scalable and easy to explain to the team without unnecessary complexity.
Product thinking
I try to see not only the code, but also the user journey, business context and practical value of the result.
Speed without sacrificing quality
I can move quickly without compromising structure, testing and overall execution quality.
