Grzegorz Hadała
Design Engineer — Fintech & Web3
I design and build fintech and Web3 products. Nearly 20 years in, I still get excited about making complex things feel simple. I work across the full stack of product design — from early concepts and design systems to writing production React code and shipping it. I prototype ideas in code, not just in Figma. I use AI-augmented workflows and progressive prompting to move faster from idea to shipped product, and I build semi-automated content and development pipelines using MCP integrations. I care about craft, clarity, and getting things out the door.
Experience

Tools & How I Use Them
Figma — Primary design tool. Heavy use of plugins and automations to cut repetitive work and move faster through ideation, iteration, and system documentation.
Framer — I build sites end-to-end: from quick early-stage prototypes to production-level company websites, including custom components, CMS structure planning, and ongoing maintenance.
Notion — I use it beyond docs — building interactive databases, internal tools, and lightweight apps that improve productivity, knowledge sharing, and team transparency.
VS Code + Claude Code / Antigravity — My coding environment for prototyping ideas fast, building automations, and writing production front-end code (React, Next.js, TypeScript).
Adobe Suite, Spline — For visual design, 3D, motion, and asset production when the project calls for it.
