I turn complex ideas into clear, working systems — from specifications and agentic workflows to production.
Complex ideas, brought into focus.
Open to ambitious ideas and complex challenges
Project universe · 01—07
Not a demo collection.
A system of real ideas.
Live products, laboratory environments, and directions that are gradually becoming working systems.
Live product and test environment
Aquanarium
A new aquarium platform with a test environment and an existing main website.
Next.js 16Ant DesignDrizzle
Open test environment
Test environment for the administrator and business owner only. Username and password required.
Open case studyFrom physical instrument to the web
Laser Surface Metrology
Online interaction with a laser instrument measuring solid-surface roughness.
Hardware integrationRealtime dataVisualization
Telemetry and environmental control
Aquarium Automation
An observation and equipment-control system for aquariums.

Development method
From uncertainty to a working system.
A specification becomes the shared map for humans and AI agents: decisions stay visible, boundaries clear, and implementation verifiable.

Production
Explore
Find the real problem, constraints, and criteria for a successful outcome.
Specify
Turn intent into requirements, scenarios, and technical decisions.
Build
Create the full-stack product with agentic engineering tools.
Verify
Validate behavior, quality, accessibility, and the production build.
Capabilities
Engineering range.
AI-native development
Agentic workflows as part of the engineering system, not a detached trick.
Full-stack systems
Interfaces, server logic, data, and infrastructure boundaries.
Product architecture
Architecture that starts with user value and grows with the product.
Hardware to web
Telemetry, measurement systems, and understandable control interfaces.
About
I like turning complexity into clarity.
I build web products and explore how SDD, OpenSpec, and AI agents change engineering itself. I am particularly drawn to work at the intersection of interfaces, data, automation, and the physical world.
