Next.js products, dashboards and customer-facing platforms.
Mobile Applications
Flutter apps with APIs, auth and production releases.
AI Systems
Assistants, automation, LLM workflows inside real software.
SaaS Platforms
Multi-tenant apps, billing, admin panels and long-lived products.
Automation Tools
Integrations, webhooks, messaging and business workflows.
Desktop Applications
Native-feel systems — e.g. Violet OS (NixOS + AI operating system).
Cloud Infrastructure
Deploy, environments, security and keeping systems live.
Product Engineering
Idea → UX → build → launch with business-aware scope.

// 02 · About
Software Engineer · Systems Designer
I'm a software engineer working across disciplines — from AI and cybersecurity to SaaS platforms and blockchain. My focus isn't only shipping apps; it's building scalable systems, sustainable products, and technology that creates real-world value.
I've built AI-powered platforms, real-time communication systems, business automation, mobile apps, content platforms, and various SaaS products. I take an end-to-end engineering approach: idea to architecture, architecture to product, product to live system.
I enjoy researching new technologies, combining different fields, and building systems that push boundaries.
For me, technology isn't just writing code — it's solving problems, creating efficiency, and shipping products that shape what's next.
