Welcome to the official source repository for SGDEV Labs (sgdev.qd.je). This platform hosts my primary personal software engineering portfolio along with an integrated open-source technical research blog.
This repository is designed with a lightweight, telemetry-free, and high-performance philosophy. It brings together my web development projects, utility software, system internals research, and cellular network telemetry studies into a single unified interface.
-
Developer Portfolio (
/index.html)- Showcases full-stack web applications, Python automation utilities, Pygame/PyQt software, and custom network tools.
- Minimalist dark-mode aesthetics optimized for speed, clarity, and cross-device responsiveness.
- direct developer contact routing via custom DNS configurations (
info@sgdev.qd.je).
-
Technical Research Blog (
/blog/)- Windows & Security: In-depth technical analysis of Microsoft Activation Scripts (MAS), Hardware Hashes (HWID), and licensing internals.
- Productivity Architecture: Enterprise Click-to-Run (C2R) deployments, Office Deployment Tool (ODT) setups, and offline licensing mechanics.
- Software Audits: Evaluating telemetry-free open-source alternatives to commercial software (GIMP, Krita, PhotoDemon, Photopea).
- Gaming & JVM Tuning: Systems optimization for Java Edition Minecraft via SKLauncher, custom G1GC flags, and low-end hardware allocation.
- Network Telemetry Case Studies: Independent RF engineering analyses, including Airtel 5G NSA signaling and LTE 1800 MHz (Band 3) anchor channel metrics.
- Frontend: Pure HTML5, Modern CSS3 (CSS Variables, CSS Grid, Flexbox) — Zero heavy frameworks for lightning-fast loads.
- Editor Environment: VSCodium / Notepad++ (100% telemetry-free development workflow).
- DNS & Routing: Hurricane Electric DNS (
dns.he.net), Vercel Edge Network, and Netlify hosting infrastructure. - Mail Routing: Hybrid mail architecture utilizing Gmail IMAP,
smtppro.zoho.inSMTP, and ImprovMX alias forwarding.
This project operates under a dual-licensing structure to preserve open-source integrity while maintaining flexibility for technical publications:
