Product management · new graduate

I ship the products
I want to use.

Building for myself is where it starts; shipping is where I learn what the market actually wants.

I finished my statistics degree in June 2026 and I am building my own products to grow into product management: user research, PRD, MVP, testing and iteration, all of it hands-on. Looking for a role where I can keep learning at that pace.

GrammarLens

In App Store review Subscription

AI-powered learning app

GrammarLens is an iOS app for English learners who speak fluently but can't reliably apply the grammar an exam like IELTS asks for. It builds practice around your own mistakes and explains them in plain language, not rule names. I did the research, wrote the PRD and made every product decision; AI coding agents wrote the code. Version 1.0 went to App Store review on 24 September 2026.

Product 04 is in discovery

The next one starts the same way: a problem I keep running into myself, then research before a line of code.

Who am I

I finished a statistics degree in June 2026. Four years of it left me with one habit that stuck: before believing a number, ask how it was collected. Most of what I bring to product work comes from that.

The rest I learned by building. GrammarLens started as my own problem: I kept correcting my English without understanding what I was getting wrong. I wrote the PRD, built the app with AI coding agents that I directed through written decision reports, and tested it with seven people. They showed me that the feature I'd built the app around, naming the grammar rule, was the thing getting in their way.

This site is the short version. It is here to show how I work rather than list everything I have done. Tools I use regularly: Flutter and Dart, SQL, Power BI, Excel, statistical modelling. I am looking for a product management role where the learning stays this fast.

How I work

I start from the problem, not the feature

GrammarLens started because I kept making the same English mistakes and learning nothing from them. My first version still carried an assumption I hadn't noticed: that naming the grammar rule was the feature. Seven people showed me it wasn't, and the product changed around what they said.

I state the real number

I tested with seven people, not seventy, and one of the interviews was with myself. Seven is not a sample, but it was enough to show me which way I was wrong. I'd rather state the real sample size than round up to one that sounds better.

I treat cost as a product decision

Every generated practice set and every graded answer calls a language model, and every call has a price. Grading the free Daily Test on the device, writing the first test by hand and capping paid practice at five sessions a day weren't technical details; they decided whether the product could exist.

I finish things

Writing the code myself was never the goal; shipping was. AI coding agents wrote it from my written decision reports, and my job was the decisions. An idea that hasn't reached a real screen hasn't been tested, only described.
