Inside the system

I'm Ketha Adhitya Valmiki, a final-year CSE Diploma student with a hacker's mindset and a builder's discipline. Deeply passionate about ethical hacking and cybersecurity - I study how systems break so I can build ones that won't.

Profile Dump

A disciplined snapshot of what drives the work, how the path evolved, and which habits keep the learning cycle moving.

</> Origin Story

The journey started in 2022 with web development and expanded into cybersecurity, system tooling, and interface customization. The core pattern has stayed the same: build something real, take it apart, and come back with a better version.

{ } What I Build

Beyond security, I craft real products - streaming platforms, habit trackers, and web apps. I leverage AI assistance to move fast without cutting quality. My stack includes C, Java, Python, HTML/CSS/JS, and React Native for mobile.

# Mission

Bridging offensive security thinking with hands-on software engineering. Learning how attackers operate so I can build things that resist attack.

>_ Operating Focus

Ethical hacking labs and foundational security practice
Frontend interfaces with sharper visual identity and stronger UX control
Linux-first workflows, especially Kali Linux, for learning and experimentation
Project work that turns ideas into visible, testable outcomes

Capability Matrix

Operational skills

This stack is presented like a capability matrix: compact, readable, and focused on the tools and disciplines that actually shape current work.

Stack Overview

The toolkit spans interface engineering, backend foundations, cybersecurity practice, and the everyday systems needed to ship clean work.

001 / Frontend

Interface Engineering

HTML5 for solid semantic structure and consistent page architecture
CSS3 for custom layouts, visual systems, motion, and dark UI work
JavaScript for interaction, flow control, and interface behavior
Tailwind CSS for fast component work when the project calls for speed

002 / Backend

Logic Layer

Node.js for lightweight application logic and tooling workflows
Python for scripts, utilities, and quick automation experiments
PHP basics for small projects or legacy environments
Problem-solving through iterative builds and practical debugging

003 / Cyber

Security Practice

Linux CLI confidence and terminal-driven workflow habits
Nmap, Hydra, and Wireshark familiarity for lab-based learning
Burp Suite for web testing and request analysis workflows
TryHackMe labs for structured, hands-on security practice

004 / Tools

Build Environment

Git and GitHub for version control and project history
VS Code as the daily development and editing environment
Figma for planning layouts before the build phase starts
