A builder’s field notes · 2024—now

I learn by making things.

I’m Xayrillo, an 18-year-old builder from Urgut. I’m interested in the unglamorous problems around me: waiting for food at a bazaar, studying with weak internet, and keeping remote work private.

How it started

Not a master plan. A chain of problems.

I did not begin with “I want to build a startup.” Each step started with something that bothered me enough to investigate.

2024 · The expensive lesson

I lost about $500 in a Telegram crypto scam.

I was embarrassed, then curious. I traced wallets, learned OSINT, moved to Linux, studied the OWASP Top 10, and completed more than 25 security labs. A bad decision became the reason I learned how trust fails online.

2025 · The first real users

A movie bot taught me that shipping changes the questions.

Movistan eventually served more than 800 people and handled around 1,200 daily searches at its busiest. The hard part stopped being “can I code this?” and became reliability, confused users, and fixing the same edge case twice.

2026 · Closer to home

I started choosing problems I could observe myself.

That led to pickup ordering for bazaar kitchens, offline driving-test practice, and a private remote-work tool. The projects are different; the instinct is the same: reduce one piece of friction, then listen.

Three yeses I could not take

Acceptance was not the finish line.

Florida Tech admission letter for Xayrillo Ne'matov
01 · Florida Tech · January 2026

The first letter made the possibility real.

Florida Tech admitted me to its BS Computer Science program. Until that email, studying in the United States was mostly an application portal, essays, and waiting. This was the first concrete yes.

The offer proved I could compete internationally. It did not solve the cost of attending.

RIT admission letter for Xayrillo Ne'matov
02 · RIT · March 2026

The strongest offer became the hardest no.

RIT admitted me to Cybersecurity and later awarded a renewable $23,000 annual scholarship—up to $92,000 over four years. It was the program closest to the work that first pulled me into technology.

Even after the scholarship, the remaining cost was beyond what my family could afford. I was admitted, but I could not enroll.

Penn State Harrisburg admission letter for Xayrillo Ne'matov
03 · Penn State · March 2026

A third yes clarified the real constraint.

Penn State Harrisburg offered me a place in Cybersecurity Analytics and Operations. By then, the pattern was clear: the obstacle was not whether a university would admit me.

The obstacle was affordability. I stayed in Uzbekistan, took the lesson seriously, and kept building instead of treating an offer letter as the final achievement.

Things I have made

Useful before impressive.

01 · Food, without the queue

Nma Yeymiz

A Telegram-first pickup tool for bazaar kitchens. Customers browse, order ahead, and collect when the food is ready. The idea came from watching delivery products solve the wrong problem for places where people are already nearby.

Honest statusThe product works; adoption is the unfinished part. Convincing busy kitchen owners is harder than writing the order flow.

02 · The difficult build

Hamma

A cross-platform SSH/SFTP client shaped by zero-trust thinking. I built connection recovery, encrypted credential storage, file transfer, packaging, and CI across Flutter targets.

What brokeA stale-connection bug exposed the lack of integration tests. An audit also found unsigned builds and weak backup-key derivation. I treated that report as a roadmap, not an insult.

03 · Learning without signal

Autotestlar.uz

Driving-exam practice for Uzbek learners, with an offline-first mobile direction. It began as a website; rebuilding it around local storage and sync forced me to think beyond the happy path.

Small lesson“Offline-first” is not a feature badge. It changes how every question, answer, and update is stored.

Results I’m quietly proud of.

No inflated dashboards. Just outcomes that meant something because a real person, classroom, or decision sat behind them.
