About my work
The interface is just
the beginning.
I build web applications and automation tools. My work connects interfaces, data and workflows — from service operations to audiovisual production.
I like working across the full path: understanding the problem, organizing the architecture, building the parts and checking how they work together. I use AI as a tool in that process, with review and explicit boundaries.

Portfolio Engineering
This site is a project too.
Projects identified in the available records and files. “Code reviewed” indicates implementation evidence, not a complete operational audit.
Tools & foundations
Every layer,
a deliberate choice.
Technologies found in the projects, organized by their role. No skill bars or invented proficiency percentages.
Frontend
Interfaces for web systems.
Backend & data
Rules, persistence and integrations.
Cloud & deploy
From code to distribution.
Creative automation
Tools for audiovisual workflows.
AI as part of engineering.
Structured plans, on-demand context and reviewable automation.
Project experience
A collection
in the making.
The experience here comes from personal projects and AI-assisted development. These are areas of work, without attributing unrecorded roles, employers or chronology.
How I build
Clarity before code.
Review after it.
A process that connects intent and implementation, leaving room to test, learn and adjust.
- UnderstandThe real problem, who uses it and what already exists.
- ArchitectData, flows and limits before the first screen.
- BuildSmall parts, tested one at a time.
- AutomateWhatever repeats becomes a logged routine.
- TestTests, visual QA and the full end-to-end flow.
- DeployDeploys with a receipt of what changed and how to roll back.
- ImproveMeasure, listen and adjust with the system live.
