Built &
shipped
Real products, real users, real constraints. Not tutorials.
benchFlow
An IT outstaffing company has to decide who goes on which client request — fast, and without over-committing anyone. Done properly that is the assignment problem, not a CRUD form.

The hard part. The matcher. A greedy algorithm left one client unstaffed to save 47 in cost — locally optimal, globally wrong. The Hungarian algorithm fills every request, and it is checked against brute force on 200 random worlds, because you don't ship an algorithm you can't prove.
Lolo Cosmetics
A real beauty brand was selling through WhatsApp screenshots — no catalogue, no stock control, no way to scale. I built the whole thing, front to back.

The hard part. Row-Level Security. When the data is someone's actual business, a leak isn't a bug report — it's their livelihood.
Attendance System
Attendance lived on paper and in Excel. One administrator spent 3–5 hours merging it by hand — every single time. I built the back-end everything else sits on.
- Role
- Back-end admin API
- Access
- 3 roles · JWT · bcrypt

- Merged & documented
The hard part. Schedule conflict detection — interval-overlap checks so a teacher or group can never be double-booked. It took more thought than every CRUD endpoint combined.
AI Knowledge
A full-stack site about artificial intelligence — written from scratch in PHP, with no framework anywhere in it.
- Auth
- PHP sessions, by hand

- CRUD · 4 entities

What it taught me. Writing authentication by hand shows you exactly what a framework does for you — and why it exists. You appreciate the abstraction only after building it once.
My Notes
A Windows desktop app written in Python — not a web app in a wrapper. You download it, install it, and it runs.
- Platform
- Windows · standalone
- Languages
- AR · EN · RU + RTL

The hard part. Shipping it. PyInstaller, an Inno Setup installer, and making it run clean on a machine with no Python. Software isn't finished when the code works — it's finished when a stranger can install it.
Java Labs
Five progressive labs: OOP, log4j2 logging, regex, XML parsing with SAX/DOM, and MySQL over JDBC.
- Labs
- 5 · progressive
- Focus
- OOP & class design
- Logging
- log4j2, not print
Why bother. Java forces you to be explicit — types declared, interfaces as contracts, class design up front. Writing the same ideas in a statically typed language made me a more deliberate Python developer.
Data Analysis
Three projects on real datasets, not tutorial ones — COVID-19 global trends, supermarket revenue, and SQL store analytics.
- Rows
- 350,085 · 255 locations
- Span
- 2020 – 2023

- Charts & insights
What stayed with me. Real data is messy. The analysis is the easy half — making the data trustworthy is the work. Validate early: that habit went straight into my back-end.
Request
lifecycle
Every system I build has the same spine. A request either gets rejected early with a clear reason, or it gets answered — never a crash.
