Nenad Kozoder

Senior Frontend Developer

10+ years of frontend development across telecom, e-commerce, business, entertainment, and streaming platforms — mostly in cross-functional teams across Europe, building clean, functional, scalable web solutions.

I translate design systems into pixel-perfect, reusable components and optimize for performance — but my work doesn't stop at the UI.

I design content models and CMS architecture in Payload and Sanity, connect APIs, and ship complete solutions editors actually enjoy using — including my own Next.js + Payload boilerplate that powers this site.

Projects

AI Seller

An AI sales assistant for online stores in Serbia, built to act like a salesperson rather than a chatbot. It asks what the customer needs, recommends one to three products with reasons, suggests add-ons and leads to the cart, without inventing facts. It handles Serbian grammar in both Latin and Cyrillic, checks order status and tracks attributed sales. WooCommerce comes first, through a plugin, while the backend and widget stay platform-independent. Currently preparing for pilot.

AltAuditor

AltAuditor is a B2B micro-SaaS that automates image alt-text for EAA/WCAG accessibility compliance. A vision-language model reads each image, a human approves it in seconds through a Tinder-style keyboard-driven UI, and it's written straight back into the client's CMS.

Ottometric

A performance-focused marketing website for Ottometric, an ADAS validation platform. Built with Next.js and React, with Sanity as a headless CMS — structured, schema-driven content that the marketing team manages independently, with Lighthouse scores in the high 90s.

Philosophy

Good software is a byproduct of good judgment — knowing when an abstraction earns its keep, when performance work actually matters to the person using the product, and when the simple solution beats the clever one. I'd rather ship something a teammate can delete in five minutes than something only I can extend.

Contact

Open to new opportunities and interesting problems — Next.js builds, headless CMS architecture and migrations, or long-term product work. Based in Kragujevac, Serbia, working remotely across Europe.
