I'm 19. For the past year I've learned AI every day and used it to build real things for real businesses. Tap any section to see what it took.

What I've built

ReviewTapReview cards built in a week, 10 sold by cold message

An NFC and QR card that sits on a business's counter. A customer taps it with their phone and lands on the business's Google review page.

What it took: I built the whole product in about a week: the card design, the website, logging every tap, and a dashboard where the owner sees taps and reviews. Unhappy customers can leave private feedback, so the owner hears about problems and can fix them. Emails go out automatically through Resend, and the data lives in Supabase.

How I sold it: I made a list of 373 Latvian businesses and scored them by priority, then messaged businesses I didn't know on WhatsApp. The first 10 cards went mostly to clinics, plus tow and car transport companies, and I invoiced them myself.

My own cold email systemInboxes, lead data and an AI SDR in progress

What it took: I set up my own Google Workspace sending inboxes on my own domains, with SPF, DKIM and DMARC, and warmed them up for three months before sending.

I find and qualify leads with data from Treg (a prepaid data API) and Apify scrapers, send through Salesforge (before that Instantly), and track every lead and reply in Twenty CRM, with a booking link for calls.

Now building: an AI SDR, a team of agents that finds and checks leads, writes each message, handles replies and books calls.

AI automation for an accounting firmSaves the team about 15 hours a month

What it took: I built generators that fill in the firm's client documents as Word forms, and Inbox Clerk, a tool that reads an emailed order or quote, turns it into rows for the accounting system and drafts the reply.

Government register checks stay with a person on purpose, because the rules expect a human to do them.

Result: about 15 hours of work saved every month.

Latvian company scanner3,779 companies from free government data, €0 data cost

What it took: a scanner that reads Latvia's open government data (tax records, the business register and filed annual accounts) and estimates where each company is losing money.

Result: 3,779 companies with 5 to 80 staff mapped at €0 data cost, so a first message can start from a number about their own business.

AI agent teams in Claude CodeAgents that split a job and check each other's work

What it took: a lead agent takes a goal and splits it between scouts that research, builders that produce and a council of agents working in parallel. An independent reviewer agent checks the result before I use it.

The agents use MCP servers to reach real tools and data, and a knowledge base I made from about 90 business books.

So far: 7 custom agents, 88 Python tools, and 2 add-ons for Claude Code itself: a live panel that shows what each agent is doing, and a meter that shows what a session costs.

AI proposal for an executive search firmThree AI solutions, after a meeting

After a meeting with an executive search firm, I prepared a one-page proposal in Latvian with three AI solutions for their team.

SEB School Ambassador programmeTop level Everest, 8 lectures, now a mentor

In 11th grade I learned investing, saving and entrepreneurship, gave 8 lectures on money to other students and finished at the top level, Everest. The same year I shadowed the programme's director. This school year I'm back as a mentor for new ambassadors.

Outside workBench press 115 kg, marathon under 4 hours, 20+ books

I taught myself to train: five years of weights, three years of running, a Rimi Riga Marathon under four hours and three years of volleyball. I built my own home gym and taught my cousin to train. Sport taught me that results come from doing the same thing every day, even when I don't feel like it.

I've read 20+ books on psychology, sales, self-improvement and finance. The two that shaped me most: Can't Hurt Me and The Success Principles.
