Hey, I’m

SDKSDK

Full stack developer • Linux & Kali power user (ethical) • Android & Windows app builder • Python + automation lover • 10+ years of writing code almost every single day.

I don’t do “half knowledge”. I’ve spent more than a decade going from HTML basics to full systems: web apps, APIs, databases, Android apps, Windows tools, scripts, automation, security, performance and everything around it. If it runs on a screen, a server or a shell, I’ve probably built something serious with it.

About

Not a “tutorial dev”. I live in this stuff.

I started with the most basic HTML and slowly worked my way through everything: frontend, backend, databases, scripting, apps, Linux, security. Not in a rush, but properly, step by step, every day, for years.

I don’t just “know” one language or stack – I’m comfortable jumping between them. PHP for backend and dashboards, JavaScript for the browser, Python for automation, Java/Kotlin for Android, C# for Windows tools, Bash for Linux – whatever the problem needs, I pick the right tool and make it work.

I’ve built big web apps, serious Android utilities, practical Windows tools, and plenty of internal scripts and automation that never see the spotlight but save a lot of time. I care about how systems behave under real usage: speed, reliability, security, and how it actually feels for the user.

On the Linux side, I’m fully at home in the terminal. With Kali, I focus on understanding real-world attacks and defences ethically: learning how things break, so I can build and harden systems properly. No childish “look at this trick” mindset – I’m interested in real security thinking.

Short version: I’m a full stack developer and power user of my tools, and I push what I use to an advanced level instead of staying in the shallow end.

Skills

Full stack, top to bottom.

Frontend

  • HTML5 done properly: semantic, accessible, structured
  • CSS3, Flexbox, Grid, custom layouts, responsive design
  • Modern JavaScript (ES6+), DOM, async code, API calls
  • TypeScript-level mindset even in plain JS (types in my head)
  • React/SPA-level understanding: components, state, routing
  • UI/UX thinking: readable, logical, not confusing for users

Backend & APIs

  • PHP for real production apps (auth, dashboards, APIs, logic)
  • Node.js with Express-style APIs
  • Python backends and tools when needed
  • Authentication: sessions, tokens, roles, permissions
  • REST-style design, JSON responses, clean error handling

Databases

  • MySQL / MariaDB – schema design, indexes, constraints
  • PostgreSQL — relational design & queries
  • MongoDB — document flows where it makes sense
  • Query optimisation, slow-query hunting, tuning
  • Backups, migrations, safe schema changes

SEO & Performance

  • Core Web Vitals in mind: speed, stability, responsiveness
  • PageSpeed / Lighthouse tweaks and fixes
  • Asset optimisation: images, fonts, scripts, caching
  • Clean URLs, meta tags, structured content

DevOps & Deployment

  • Linux servers from scratch: setup, users, permissions
  • NGINX / Apache configuration for real traffic
  • Basic Docker usage for isolating environments
  • CI/CD mindset: automate builds, tests, deployments
  • Monitoring logs, watching uptime, reacting to issues

Apps (Android & Windows)

  • Android apps in Java & Kotlin with real features
  • Custom UI, offline-first logic, API integration
  • Background work, scheduled jobs, handling failures
  • Windows apps in C#/.NET (WinForms and basic WPF)
  • Desktop tools for automation and daily shortcuts

Tech

What I actually use and control.

Languages

  • HTML, CSS, JavaScript
  • TypeScript (used where it helps)
  • PHP
  • Python
  • Node.js (JS runtime)
  • Java / Kotlin (Android)
  • C# (.NET / WinForms)
  • Bash / Shell
  • SQL (MySQL, MariaDB, PostgreSQL)
  • MongoDB basics

Linux & Automation

  • Linux as daily driver: terminal, tools, workflows
  • Bash scripts for repetitive work and ops
  • Cron jobs, services, log monitoring
  • SSH, remote management, basic firewall rules

Kali & Security Mindset (Ethical)

  • Kali Linux used seriously, not for screenshots
  • Understanding recon, enumeration, weak points
  • Seeing systems from an attacker’s eyes (legally)
  • Using that knowledge to harden applications
  • Python + Bash tools for analysis and automation

Work

Some of what I’ve actually built.

Full Stack

Custom Web System

A full web platform with login, user roles, admin panel, reporting and more. Built from scratch, front to back, with performance and stability as priorities.

  • PHP
  • MySQL
  • HTML/CSS/JS

Android Utility Apps

Multiple Android apps built to actually be used daily: offline features, smooth UI, predictable behaviour, and stable performance instead of demo-level features.

  • Android
  • Java / Kotlin

Windows Automation Tool

A Windows desktop tool that automates repetitive tasks, file operations and other boring work, wrapping it all into a simple interface.

  • Windows
  • C# / .NET
  • Automation

How I like to work

I prefer clear problems, straight communication and real responsibility. I don’t chase hype; I care about building systems that actually work, stay fast and remain maintainable. If you need someone who understands the whole picture, not just one small layer, you’ll probably enjoy working with me.
