Frontend Developer / Sweden
Oscar Ahlgren
Welcome to my CV.
Developer Profile
About
About me and the way I work.
I am a frontend developer from Sweden with a strong focus on React, Next.js, TypeScript, and building clean, scalable user experiences. I enjoy solving problems, working with APIs, and turning ideas into well-structured products.
Quick Overview
React
I use React in most of my daily work, both in product development at Svenska Spel and in my own projects where component structure and clean UI logic are important.
Next.js
I have used Next.js in projects such as my AI transcription website, where routing, structure, and a solid frontend setup have been an important part of the work.
TypeScript
TypeScript is a natural part of how I work. I use it to keep code more predictable, easier to maintain, and safer to build on over time.
APIs
I enjoy working with APIs and data flows, including uploads, AI services, and payment-related flows where the frontend needs to handle the user journey clearly and reliably.
UI Animation
I like adding motion where it improves the experience. That can mean subtle transitions, hover states, or interactions that make the interface feel clearer and more polished.
Problem Solving
A big part of my work is breaking down problems, discussing solutions with the team, and finding practical ways forward when building real products under real constraints.
Experience
Professional experience built around frontend delivery, collaboration, and product thinking.
A timeline that shows both technical growth and the people skills behind strong product work: ownership, communication, and the ability to turn ideas into polished experiences.
