Stevan Leonardy
Full-Stack & AI Engineer · Founder of Nuteja
Since 2019 I've shipped products end-to-end: React and React Native up front, Go and Laravel services behind them, AWS and GCP underneath. Today I run Nuteja — an AI-first software company in Indonesia — and build SaaS products like Teman Undanganku.
From First Commit to Production
I hold a Bachelor's degree in Information Technology and have been building software professionally since 2019 — 7+ years across web, mobile, and data. I'm usually the engineer who takes a product from the first wireframe to production infrastructure, not just one slice of it.
My day-to-day stack is React, Next.js, and React Native on the front end, with Go and Laravel services behind them on AWS and GCP. Lately much of my work is AI engineering: LLM-powered generation pipelines, prompt-to-product features, and the unglamorous plumbing that makes them reliable in production.
I founded Nuteja (PT Nusa Techno Jaya), an AI-first software company based in Indonesia, where I build and operate SaaS products end-to-end — currently Teman Undanganku, an AI-assisted digital invitation platform for Indonesian celebrations.

What I'm Building
Teman Undanganku
An AI-powered digital invitation platform for Indonesian celebrations — weddings, sangjit, khitanan, aqiqah, birthdays, graduations, and more. Describe your event and the AI composes a complete invitation concept: color palette, typography, copywriting, and a matching design family.
Inside the Product
Nuteja
Nuteja (PT Nusa Techno Jaya) is my software company: AI-first IT solutions for businesses in Indonesia and beyond. Every product I ship — including Teman Undanganku — is built and operated under it.
What We Build
Available on Fiverr
Need Something Smaller Than a Company Engagement?
I take freelance projects on Fiverr: web applications, mobile apps, API and cloud work, and AI integrations. You get the same engineer who builds production SaaS — with a clear scope, honest estimates, and professional delivery.
