Building AI products solo, in public

I ship AI products solo.
The hard part was never the code.

Eleven years building products across FinTech, EdTech, and enterprise. One exit, 275K users in 69 countries, 150+ teams mentored. In the last nine months I built 6 AI products hands-on with Claude Code — and learned that when building gets cheap, judgment becomes the whole job.

How I think

When building gets cheap, judgment is the job.

01

Shipping isn't the bottleneck

Claude Code writes the code. So the question stopped being "can we build it" and became "should this exist, and who is it for." That selection is the work now.

02

The demo is not the product

In enterprise AI, teams celebrate the demo — then find out distribution and evals were the actual product. I build for the second part.

03

Evals over vibes

A feature without an eval is a guess. I write the eval before the feature, so I know whether a model change helped or quietly broke something.

04

Teaching keeps me honest

Explaining product to 150+ teams forces the thinking to be simple enough to be true. If I can't teach it, I don't understand it yet.

Work

What I've actually shipped.

I don't talk about AI products in the abstract. I build them, ship them, and read the analytics — including for the ones that flopped. Every link below is a live deployment.

Products

Six products. One backend. Built solo.

Same AI core, same auth, same Supabase across all six. When a new product costs days, the hard call is which ones deserve to exist.

About

How I got here.

I'm Dmitry — an AI Product Leader with 11+ years building B2B SaaS across FinTech, EdTech, Smart City, and HoReCa. Built four product teams, mentored 150+ teams, and shipped to 69 countries.

At OTP Bank I led AI Discovery: built a RAG system on the corporate knowledge base, deployed multi-agent assistants, and ran an internal AI marketplace at 90% NPS. Top-5 speaker at ProductConf 2025.

As CPO at Sergek (Smart City SaaS, Kazakhstan) I audited 8 products, cut legacy by 50%, deployed Computer Vision on millions of camera records, and ran international pilots in the Philippines, Indonesia, and Thailand.

Before that I co-founded Doshkola Tilly and scaled it single-handedly to 275K+ users across 69 countries, 4× revenue, and an exit. I also teach founders to ship with AI — which keeps my own thinking honest.
