Hi, I'm Hien Dinh.
Software Engineer
I build data-heavy products: payment reconciliation, data pipelines, reporting tools and, more recently, apps that use AI. In my free time I build my own products.
About
Engineer, data person, builder
I'm a full-stack software engineer and have been working professionally since 2014. I've built systems that handle a lot of transactions and data, including a real-time reconciliation platform for a mobile money wallet, high-volume log and data pipelines, and reporting portals that teams use every week.
I care about data integrity, clean processes and tools that remove manual work. I'm currently studying for a Master of Science in Information Studies at Trine University.
Outside of work I'm happiest building my own ideas. I take something that bugs me, like a recipe that doesn't fit the cut of meat I bought or a song I want to understand better, and turn it into a real product people can use.

Side projects
Things I build in my free time
Small, real products I designed, built and shipped myself. Each one started as an idea I wanted to exist.
Undertone
The meaning beneath the music
Type a song and Undertone loads the lyrics, highlights the lines that matter, explains the meaning line by line, links you to everywhere you can listen, and finds songs with a similar message.
- Line-by-line notes on meaning and literary devices
- Listening links for Spotify, YouTube, Apple Music and more
- Song recommendations based on shared themes
Nêm
Scale a YouTube recipe
Paste a cooking video link. Nêm reads the ingredients list in the description (in Vietnamese or English), scales every amount to the cut of meat you bought, and shows when each batch goes in the pot.
- Parses ingredient lists from YouTube descriptions
- Scales every quantity from one input
- Built for Vietnamese and English cooking channels
Until
Count down to the days that matter
Count down to a future day, get a text message every day or every week, and keep the notes and pictures afterward.
- Countdowns to any future date
- Daily or weekly text reminders
- Keeps your notes and photos as a memory
Let's build something together
I'm open to software engineering and data roles, collaborations, and conversations about AI and side projects.
