Web developer building with React and Next.js.
I'm Klemen. I've worked with React and Next.js since 2021, picking up work across the stack when needed: backend endpoints, CMS rebuilds, web3 integrations, and deployment.
Who I am
I'm a web developer based in Slovenia. I learned by building small projects on my own, and I've been doing it professionally since 2020. I studied Informatics at Višja strokovna šola Novo mesto.
My focus is React and Next.js, but I'm comfortable across the stack — writing backend endpoints, reworking CMSes, wiring up data and web3/wallet integrations, and handling deployment and maintenance on Netlify and Coolify.
Where I've worked
Web Developer · Dekrypt d.o.o.
2022 — Present- Build and maintain production React / Next.js applications, taking features from UI through to release.
- When a project needs it, I also work on backend endpoints, data layers, and integrations.
- Handle deployment, monitoring, and ongoing maintenance across Netlify and Coolify.
- Deliver client projects for partner companies on a contract basis through Dekrypt, often as the lead frontend developer.
Before Dekrypt, I was a student developer at I.T.I. (Miha Bradač s.p.), working on WordPress sites and handling technical support and diagnostics.
2020 — 2022Things I've built
HashArcade
A crypto arcade with several games, including a mining game where players stake and earn real crypto and prediction-market titles. I built the game frontends across the catalog: lobby shells and in-browser UIs with real-time play wired to the platform backend.
Sachi
Gaming metaverse where players browse games, earn rewards, and manage items. I took over the player frontend from another team, fixed issues, shipped new features, and owned the dashboard: wheel of fortune, user management, an items marketplace, a leaderboard, and poker integration.
Physifit
I built a multilingual wellness studio site with online booking, Stripe checkout, and a staff admin for calendars, sessions, and patients. Clients pick a time and location, pay online or on-site, and staff manage the schedule from a built-in dashboard. The site runs in English, French, and Slovenian.
Medicina Volovec
Production platform for a medical and aesthetic clinic. Staff manage treatments, news, team profiles, and scheduled promos in three languages, then publish to the live site with one click. I rebuilt it end to end: custom React admin CMS, backend APIs, and the multilingual public website, replacing a legacy Laravel stack.
Skala
I built a bilingual company site for a grain-trading and real-estate firm: Prismic-powered news, live commodity price dashboards, investment project pages, and secure contact forms in Slovenian and English.
Web3 client work
At Dekrypt I also delivered crypto and blockchain projects for clients, from marketing sites to full applications with wallet connection and on-chain flows.
I built the React and Next.js frontends and wired up the web3 side too: wallets, contracts, IPFS, The Graph.
