I’m Aren Seferi, and Korbnet AB is my independent development studio in Stockholm. You work directly with the person designing and writing the code — without unnecessary handoffs or template-driven delivery. Each project is scoped around what it actually needs, built on a modern technical foundation and taken through to production.
Most work is delivered for clients in Sweden. Projects can also be delivered internationally, including production work for the Albanian market.
Marketing sites, project sites and company websites built around the actual content and business need rather than adapted from a generic theme. That includes information structure, responsive implementation, content management where needed, accessibility, performance and the technical foundations required after launch.
Custom web applications with real workflows behind them: search and discovery, publishing tools, dashboards, role-based access, APIs and administrative interfaces. Work can cover the data model, backend, frontend and the internal tools required to operate the product.
Frontend and full-stack development with Next.js, React and TypeScript, including server-rendered applications, statically generated sites, component systems and data-heavy interfaces. Work can also involve extending, upgrading or stabilising an existing codebase rather than replacing it.
AI integrations for specific product workflows, including assistants, voice interfaces, retrieval-based experiences and structured automation. The focus is on solving a defined task rather than adding AI for its own sake.
Analytics implementation focused on useful questions: event and conversion tracking, behavioural analytics, consent-aware measurement and reporting that helps identify where users struggle or where a funnel can be improved.
Technical work covering structured data, metadata, internationalisation, image optimisation, crawlability and frontend performance. Usually delivered as part of a build or improvement project rather than as generic SEO content work.
Ongoing development after launch: new functionality, fixes, technical improvements and keeping the application and infrastructure current. Several client relationships have continued across multiple phases or projects.
You talk to the developer building the project. Questions are answered by the person who knows the answer, and decisions don’t pass through an account layer.
Scope is agreed up front against what the project actually needs. I would rather build the right smaller thing than pad a proposal, and I’ll say so when something isn’t worth building.
Once we’ve talked through the project I give a clear estimate and a sensible way to approach it. Larger builds are delivered in phases, so you can see progress and adjust before committing to the next stage.
Korbnet is intentionally small and direct. Scope, communication and implementation stay close together, so the work stays focused on what the project actually needs.
Tell me what you’re building and what you need help with.
