🧠 Personal Profile

I design and build safety-first, failure-aware systems — not demos, not tutorials, not throwaway prototypes.

My work focuses on real-world platforms where dropped connections, partial failures, stale commands, and human error are expected — not ignored.

I don’t just make things work.
I design how they fail, recover, and remain observable under stress.

🏗 What I Do

• Architect fault-tolerant, safety-first systems
• Design control layers, authority models & failure boundaries
• Build full-stack platforms with real-world constraints
• Create observable, debuggable, replayable systems
• Design for continuity, not ideal conditions

---

🏢 What I Currently Run

• An LTD technology company building apps, websites, and custom software
• A UAB company holding land for private cabin stays, where I design and operate all systems front-to-back

🚀 Flagship Platforms

🏕 CabinApp — Private Cabin Stay Platform

A real, operational hospitality system.

Features:

• Customer booking experience
• Owner/admin dashboard
• Backend APIs & database logic
• Automation & internal tools
• Built as a business system, not a prototype

---

🕸 Harness — Safety-First Control & Mesh Networking Platform

A modular control platform designed around failure modes, authority separation, and continuity-first networking.

Focus areas:

• Formal state machines (SAFE_IDLE, ARMED, ESTOP)
• Command aging, heartbeats, watchdogs
• Authority arbitration (human vs autonomous)
• Kill paths & safe-state degradation
• Mesh-style relay concepts for extended range
• Multi-transport resilience (WiFi, Bluetooth, RF-class concepts)
• Dead-stop elimination
• Replayable command streams & post-mortem analysis

This is not a toy project.
It is a systems engineering exercise in building control software that behaves predictably when things go wrong.

🔗 Unified Narrative

This GitHub profile aligns with my CV and LinkedIn:

• Builder, not learner
• Owner, not contractor
• Systems, not snippets
• Production over theory
• Safety over speed

I design systems that fail safely, not silently.

I don’t build for perfect conditions.
I build for the real world.

Where things break.
Where signals drop.
Where humans make mistakes.
Where systems must fail safely.
