About

I started coding in 2023 with C#. Later I got into web development, backend stuff and systems programming. Most of what I know comes from building my own projects and running them myself. Frontend, backend, database, payments, bots, servers, and answering users when something breaks.

I also spend a lot of time on security. Some of my projects handle real users and payments, so I have to take authentication, permissions and payment verification seriously. I encrypt the traffic between my apps and the server, and I don't trust anything that comes from the client.

Outside of client work I'm into reverse engineering. I like digging into how other anti-cheat and anti-tamper systems work, and I use what I learn to make the protection in my own software harder to break.

I usually handle a project myself from the idea to launch, and I keep maintaining it after it's live.

Skills

Backend & Databases

Most of my backend code is TypeScript on Node.js. PostgreSQL is the database I use the most.

Payments

I've set up card, PayPal and crypto payments. Nothing gets delivered until the payment is confirmed on my side.

Bots & Mini Apps

Telegram and Discord bots, usually hooked up to a backend and a database.

Experience

  1. 2023

    Started with C#

    Wrote my first code in C#. Made a few small Windows tools. One of them watched a process and restarted it every time it crashed.

  2. 2024

    Web dev and security

    Spent most of the year learning web development: React, Next.js, Node.js, SQL. I also started learning cybersecurity. How common web vulnerabilities work, auth, encryption, and some reverse engineering.

  3. 2025

    Started Phantom Softworks

    Built my own online store from zero. Accounts, an admin panel, card, PayPal and crypto payments, and license keys that get emailed automatically after purchase. Around the same time I launched my VPN, which hands out access keys automatically.

  4. 2026

    C++ app and my own crypto payments

    Made a desktop app in C++ with its own license activation. I also dropped the third-party crypto processor I was using and wrote my own payment checks. The server looks up each transaction on the blockchain.

  5. Now

    Freelancing

    Taking freelance work. Websites, backends, Telegram bots, payment setups.

Projects

E-commerce & Licensing Platform

My own store. It has user accounts, an admin panel, a few different payment methods, license keys that get delivered automatically after purchase, and a public status page.

VPN Service

My own VPN. No logs. Access keys are issued automatically, and there are clients for Windows, macOS, Android and iOS.

Telegram Bot & Mini App

A Telegram bot with a Mini App inside it. It talks to my backend for accounts, orders, key delivery and notifications.

Desktop Application

A native desktop app I wrote in C++. It has its own activation and licensing system.

Crypto Payment Gateway

My own crypto checkout, no third-party processor. The server looks up every transaction on the blockchain itself before the order goes through.
