Frontend Engineer

Jakub Dyrszka

Building fast, clear, and practical web applications.

I build applications by starting with the real problem: user workflows, technical constraints, and product decisions that matter. AI speeds up execution, while direction, architecture, and quality control stay with me.

PROBLEM ANALYSIS & DECONSTRUCTION

Systems Thinking & UX

[ STEP 01: LOGIC ]
DECONSTRUCTIONDomain Logic Analysis
Breaking complex real-world workflows into clear business rules before coding.
UX / UICognitive Friction Reduction
Building intuitive, clean, and error-resistant user journeys.
DIAGNOSTICSRoot-Cause Problem Solving
Systematic bottleneck detection and surgical optimization of system logic.

I treat software as a precision mechanism: every interface element must serve a clear purpose, respond instantly, and support intuitive navigation without friction.

FOCUS: WEB APPLICATIONS & PRODUCT SYSTEMS
WORKFLOW: PRECISION & AI

01 / BACKGROUND

Systems Architecture & Intuitive Interfaces

I approach software development through systematic diagnosis: user workflows, root causes, and technical constraints before implementation. The result is frontend software designed for clarity, speed, accessibility, and daily use.

02 / APPROACH

How I work

Diagnosis Before Code

I map user workflows and technical constraints before touching the keyboard. Solid architectural planning prevents costly refactoring later.

AI Acceleration & Verification

I use language models to prototype quickly, compare options, and uncover edge cases. The saved implementation time goes back into code review, accessibility, and performance work.

End-to-End Ownership

I take projects from initial concept to working deployment. Technical decisions are measured by their effect on users, reliability, and future maintainability.

03 / AI & ARCHITECTURE

Modern AI Product Builder Workflow

Artificial intelligence speeds up execution, but it does not replace product responsibility. I use LLMs for prototyping, repetitive tasks, and edge-case analysis. System design, data safety, and code quality stay on the human side of the workflow.
