I make complex products feel simple and fast.
Frontend developer with full-stack range, focused on React, Next.js and real-time 3D for the web. I've shipped 20+ products — SaaS platforms, ERP systems, 3D configurators and marketing sites — and built StaffSync, a full workforce-management platform spanning a NestJS backend, web dashboards and a React Native app.
I'm a frontend developer who likes living where design, performance and 3D meet. Most of my work is in React, Next.js and TypeScript, but I'm just as comfortable dropping into a NestJS backend or shipping a React Native app when a product needs end-to-end ownership.

StaffSync — a workforce-management platform (backend, web dashboards, mobile app)
Full storyOpen +Close −
A big part of what I do is real-time 3D on the web — car configurators, hotel digital twins, product viewers and geospatial tools built with Three.js and React Three Fiber. The interesting challenge there is never just "make it look good"; it's making it look good while staying fast on a mid-range phone.
I've contributed to large team codebases (a 30+ module Vue 3 ERP, a two-app geospatial SaaS suite) and shipped numerous solo marketing sites and configurators end-to-end. Recently I built StaffSync, a workforce-management product, from the database schema up to the mobile app.
I care about the boring fundamentals that make products trustworthy: accessibility, Core Web Vitals, clean state management, type safety and real observability in production.
What I do
- Interactive frontends in React, Next.js and TypeScript
- Full-stack features with NestJS, Prisma and PostgreSQL
- Cross-platform mobile apps with Expo / React Native

A frontend-first toolkit with deep React/Next.js experience, a strong specialty in real-time 3D, and full-stack reach into NestJS, Prisma and React Native.

How I build
I think about software in layers: a clean data and API boundary, a predictable state layer, and a fast, accessible UI on top. Whether it's a marketing site or a multi-tenant SaaS backend, the same instincts apply — make it correct, make it fast, then make it delightful.
Working philosophy
“I'm pragmatic about tools: React/Next.js and TypeScript as a base, Three.js/R3F when the product needs 3D, NestJS/Prisma when I need a real backend, and the lightest state solution that fits (Zustand, MobX or just TanStack Query). The stack serves the product, not the other way around.”
Speed isn't a final polish step — it's a constraint I design around from the start.
Especially with 3D, I budget for performance up front: optimized GLTF assets, on-demand model loading, marker clustering, row virtualization and query caching. The goal is a scene that still feels smooth on a mid-range phone, not just a flagship laptop.
