Startups and Entrepreneurship

At the age of 15 he began studying about startups and entrepreneurship, and has been involved in the startup ecosystem since then. Later at the age of 18 an online friend working at Fillout (San Francisco, California) offered to recommend him for a job as a senior software engineer at the company, due to his "high competence". He got to the last interview stage but ultimately did not get the job.

In December 2025, he joined a pre-seed remote AI startup building an AI-powered SaaS product for real estate agents. He was promoted to technical co-founder just a week later after meeting for a coffee with the founder in Vienna, Austria. His co-founder was business-oriented and design focused, while Dino was responsible for the technical side of the product, building a Next.js web application with a Convex backend in collaboration with the founding engineer, and contributing to marketing and go-to-market strategy. He ultimately left the startup in March 2026 due to differences in vision and direction for the product and company.

Freelancing and Personal Brand

For his uncle's company, he built a website for a local painting business as a contractor, which is live at df-malerei.at ^[4] . The project reduced the company's operation costs by 91% and tripled their traffic through optimized SEO and Google Business, significantly improving their online presence.

He is currently building a membership infrastructure platform aimed at SMBs in the DACH market.

His personal site dino-kupinic.dev serves as a portfolio for his projects and a platform to share his thoughts and insights on software engineering and technology. He regularly updates his blog with articles on various topics related to software development, entrepreneurship, and personal growth. In February 2026 he additionally acquired the domain dinokupinic.com ^[5] .
