Writes about
Projects I have worked on, consumer app teardowns, retention, and working with AI

I like building products for ordinary people, and what I care about most is what happens after launch: do they come back? On the UOSLIFE team, I developed backend features for real-time chat, club recommendations, and a game scoreboard API. I led UosAsk, a notice chatbot students used, handling its backend and infrastructure. On Mili-Stock, I worked as PM and backend developer, from interviews to a proposal to the military welfare agency. Now I work on the DocentPro team, focusing on place extraction, hotel pricing and booking. I work with AI agents every day to get from an idea to a working feature.

What I want to build

Consumer products people open on an ordinary day, not only when they need them.

Here I write about the projects I have worked on, take apart consumer apps I use, and share how I work with AI.

How I work

  1. 01

    Test whether something is really impossible before finding a workaround.

    Most walls I have hit turned out to be assumptions. One direct test is cheaper than a week of workarounds.

  2. 02

    Measure how often it happens before fixing it.

    I want to know how often a problem happens and to whom. A fix for a rare case should not change what everyone uses.

  3. 03

    Decide first, then write the code.

    Cause, scale, options, decision. Code is the last step, not the way to think out loud.

  4. 04

    AI agents do the work; I decide what matters.

    I work with several AI agents every day. They work quickly; I decide what matters.
