He / Him · Frontend developer

I ship interfaces as a freelancer and with product teams.

From client sites and owned products to Vue-heavy apps at companies like Xyrality and Baqend—I care about clear UX, solid architecture, and shipping. Day to day I use AI-assisted development workflows and LLM-based tooling in the editor to iterate faster while keeping clear ownership of quality and design.

Two ways I work

Freelance and employed—same craft, different context

Whether I am building for clients, my own products, or inside a company team, the through-line is thoughtful frontend engineering and shipping what users actually need—with practical use of AI tools in both freelance and employer contexts, always alongside architecture, review, and user outcomes.

OpenStuds

OpenStuds is a community-driven marketplace for brick MOC (“My Own Creation”) designers, built to enable creators to publish, showcase, and monetize their original models. The platform combines marketplace functionality with community features, allowing users to upload designs, maintain creator profiles, and engage with other builders. Beyond transactions, it emphasizes quality through structured content guidelines, curation processes, and standardized presentation. From a technical perspective, OpenStuds represents a full end-to-end marketplace system, including creator onboarding, content management, product distribution, and user experience design.

BrickTreasure

BrickTreasure is a LEGO-themed case-opening platform that applies gaming mechanics to digital commerce, serving around 2,000 users. Users interact with randomized “cases” that yield different rewards, creating a probability-driven experience similar to loot systems. The platform is designed for engagement and retention, combining instant feedback loops with a lightweight, responsive frontend. I built the system end-to-end, including architecture, frontend, backend (Supabase), and deployment, with a focus on scalability and smooth UX.

BidBro

BidBro is a live-stream auction platform for brick collectibles, built end-to-end. It enables real-time auctions where users can watch live streams, place bids, and interact within a fast-paced environment. The system required implementing live-stream integration, real-time bidding logic, and a responsive interface that supports synchronous user interaction. The project combines elements of live media, marketplaces, and real-time systems, with a strong emphasis on reliability and user experience under time-sensitive conditions.
