Sharpfrontend.Cleancode.
I build polished interfaces with React, Next.js, and TypeScript — with care for UI, performance, accessibility, and code a team can confidently extend.
I'm Konrad — a frontend developer with an eye for UI and a habit of keeping the code clean.
I do my best work where an interface needs to be fast, responsive, and visually considered. I like building components that feel light on the surface, but have clear TypeScript, predictable states, and a tidy structure underneath.
I use AI to move faster, not to stop thinking. What matters to me is still the craft: accessibility, performance, communication, and code the next person on the team can build on without dread.

Want to see how I work in practice?
Let's walk through the projects on a call.
The stack I use to ship production interfaces.
No decoration for decoration's sake.
I mostly work in the Next.js or React ecosystem: components, routing, forms, animation, performance, accessibility, and API integrations.
I bring frontend that is visually precise and technically calm enough to maintain.
Frontend Engineering
I build React, Next.js, and TypeScript components with clear APIs, predictable state, and code that can keep growing after the first release.
UI & Motion
I care about responsive layouts, microinteractions, type rhythm, and animation that helps people understand the interface instead of just decorating it.
Product Thinking
I do not stop at JSX. I think through users, requirements, edge cases, and how to get from an idea to something shipped and usable.
Understand the problem
I start with context: the goal, the user, the constraints, and what actually needs to change in the product.
Shape the solution
I break the work into states, components, and flows. If something is unclear, I clarify it before it becomes debt in the code.
Implement
I write TypeScript-first frontend while keeping an eye on responsiveness, accessibility, performance, and clear ownership boundaries.
Test and iterate
I check edge cases, polish the details, and leave the solution in a state that can be extended without digging for missing context.
Care for detail
I pay attention to the things that are easy to miss: spacing, hover and focus states, empty states, transitions, contrast, and small inconsistencies that make a product feel unfinished.
Clear communication
I would rather name a risk early, ask for missing context, and show progress than silently deliver something the team does not need.
AI as workflow leverage
I use AI for faster research, prototyping, and solution checks, but the technical decisions, quality, and responsibility stay with me.
Ownership of the outcome
I do not treat a task as done just because the code compiles. I care whether the interface works, makes sense, and can be maintained.
