Lucas Sierota
UX engineer and Systems thinker
I design tools that reduce friction, clarify workflows, and align teams around real human needs. I don't jump to solutions. I explore context, trace friction, and model human behavior. Sometimes that leads to a better UI, sometimes to better process. Either way—what I build grows from how people actually think, feel, and take action.
Clients I've worked with
Case Studies
Real projects. Real problems. Interfaces built to remove friction, scale clarity, and support better decisions—fast.
Case study
Bringing Web3 loyalty to mainstream users
Europa is a white-label loyalty engine for web3-native brands and enterprises, powering tokenized rewards, access, and social integrations at scale.
I hired Lucas Sierota as a Software Engineer (web3) for Europa Labs, when I was their VP of Engineering. Lucas was very well-rounded, onboarded to our tech stack quickly, and was able to execute on new features autonomously. I would hire Lucas again at my new company if I could.
Services - What I Do
I design, build, and ship thoughtful web interfaces—from idea to production.
- Interface Design. Interfaces shaped by real behavior, not assumptions. Think: fast, intuitive, effortless.
- Frontend Engineering. Clean, scalable code built with React, Tailwind, and real-world edge cases in mind.
- Workflow Optimization. Custom internal tools and workflows to make teams faster, more aligned, less stressed.
- Problem Framing. Sometimes the bottleneck isn't the code—it's the process, people, or how the problem is being framed.
