I build to understand. My work moves between product interfaces, APIs, systems tooling, distributed applications, networking and security research. I am at my best when a new language, environment or problem needs to become a useful, well-documented piece of software.
|
Product engineering Web applications, APIs, service flows and cross-platform experiences. Systems & performance Rust, Go, Linux, CLI tooling, caching, networking and concurrency. |
Technical range Backend, frontend, infrastructure, mobile and developer tooling. Security specialization Applied security, defensive tooling, network analysis and forensics foundations. |
|
CacheCraft ↗ GO · PERFORMANCE ENGINEERING LRU caching, Redis integration and resilient application design. 
|
buy-01 ↗ JAVA · DISTRIBUTED PRODUCT Full-stack commerce platform exploring backend architecture and product delivery. 
|
|
language-installer ↗ SHELL · DEVELOPER EXPERIENCE Practical language-setup automation with a clear developer-experience focus. 
|
Multiplayer FPS ↗ RUST · REAL-TIME COLLABORATION Collaborative real-time project demonstrating systems thinking and networked-programming exposure. 
|
|
Real-time Forum ↗ GO · COLLABORATIVE WEB SYSTEM Collaborative web application work with real-time concerns and shared code ownership.
|
Applied security DEFENSIVE RESEARCH · LAB WORK Controlled research, defensive tooling, network diagnostics and image analysis. Sensitive lab material stays access-controlled.

What is behind the public showcase?
Some work is private while it is being documented, hardened for publication or contains sensitive laboratory material. The projects above are selected to show real breadth without exposing unsafe or unfinished content.

Read the toolkit honestly
These badges represent technologies I have used across projects, learning tracks and product work. They are not a claim of equal seniority in every technology; repositories and project notes are the evidence of depth.
| 01 / Curate Turning real work into clear public evidence. |
02 / Build Systems, product engineering and developer tools. |
03 / Learn Security research with safe, responsible sharing. |

Signal Drift ↗ CANVAS · INTERACTION DESIGN · JAVASCRIPT A playable micro-experience built with responsive pointer input, collision logic and local high-score persistence. It is a compact public study in visual systems, motion and feedback. 
|
Why a micro-game? PUBLIC BUILD · SMALL SCOPE · REAL EXECUTION It turns a profile into a place to explore—not only a list of links—while demonstrating browser APIs, responsive input handling and purposeful visual polish. |
|
ScoutHub-PC PRODUCT PLATFORM · NEXT.JS · POSTGRESQL · DDD Product work for a public storytelling and youth-programme platform, using Next.js, PostgreSQL/Drizzle and Clean Architecture patterns. Source stays private while the product is developed and reviewed. |
Kalend SCHEDULING SAAS · GO · WORKFLOW DESIGN Appointment and workflow product work focused on backend logic, service design and practical operations. Private because it is a product-in-progress, not an open-source artifact. |
|
0-shell RUST · SYSTEMS EXPLORATION A systems-oriented shell project exploring command execution, process-facing concepts and robust command-line ergonomics. |
Security labs CONTROLLED RESEARCH · DEFENSIVE LEARNING Sandbox-based reverse-engineering and behavior-analysis exercises used to develop defensive detection thinking. Material that could be misused is intentionally not published. |
Publication standard. Private work is represented by accurate architecture, product and learning summaries—not by pretending it does not exist, nor by exposing client material, code or laboratory assets that should remain controlled.
