systems.

Software Developer & Cybersecurity Researcher

I design and build complete, production-grade systems end-to-end — from backend and databases to web consoles, native apps, and custom protocols — with data sovereignty, offline resilience, and tamper-proof auditability at the core.

About
Who I am

I'm a software developer and cybersecurity researcher (currently also studying cybersecurity). I build complete, production-grade systems solo — backend, web, native apps, computer vision, and custom protocols — with security and data sovereignty at the core.

My work centers on systems that must keep running and stay trustworthy under pressure: no mandatory foreign cloud, working offline, and tamper-evident audit trails. I've shipped platforms for life-critical emergency response, public institutions, and security research.

I work across a broad stack and pick the right tool for the job: Python, Node.js / Next.js, .NET, Rust, Flutter, PostgreSQL / PostGIS, Docker, plus applied security — audit hash-chains, zero-knowledge proofs, penetration testing, OSINT, and computer vision.

Sovereignty

Self-hosted, zero foreign-cloud dependency.

Security by design

Tamper-proof audit, encryption, strict access control.

Resilience

Offline-first; works when networks fail.

Built for institutions

Emergency services, ministries, public sector.
