HELLO, I’M
Full-Stack Developer & Designer
Turning good ideas into
thoughtfully crafted digital experiences.
01 / SELECTED WORK
An idea behind every project,
a reason behind every detail.
An operations program that runs a manufacturer's entire operation — from orders and delivery to branches and accounting — on one screen.
A security control centre I designed to help WordPress site owners understand and manage security with ease.
An online store reaching shisha and accessory enthusiasts around the world from Türkiye, kept lively by its campaigns.
A two-sided digital store through which a growing women's fashion brand reaches both its customers and its dealers.
An international platform connecting patients from around the world with Liv Hospital.
View project ↗A new web experience that tells the story of a US kitchen and bath remodeling company through real customer stories.
A bilingual product catalogue connecting an industrial and automotive spare parts supplier with buyers around the world.
A personal health platform where an interventional cardiologist informs patients about non-surgical treatment options in two languages.
02 / WHAT I DO
Bringing design and development together
to focus on the whole idea.
From idea to working product. Fast, accessible web experiences that work across screens.
Interfaces that look good and feel clear. Solutions built around the people who use them.
Implementation that preserves the details of a design, from the first sketch to the final interaction.
03 / ABOUT ME
I’m Yunus Emre Balçın. I bring software development and design together to create digital experiences.
To me, a good product connects how it looks, how it feels and how it works. Small details make a difference to that whole.
How I work ↘04 / PROCESS
Start by understanding the need, the goal and the people who will use the product.
Make the idea tangible through structure, visual language and interaction.
Turn the design into a working experience with clear, maintainable code.
Check across screens, refine the details and deliver.

Google's AI features do not ask for a special file or markup; the page has to be indexed and eligible to be shown with a snippet. A checklist that separates request, crawl, index and selection, and says what can and cannot be measured. Last checked: 25 October 2026.

I build software together with AI agents: Codex plans and reviews, Claude implements, and I set the direction and make the final call.
Agent development environment
My main workspace, where I run Claude Code, Codex and Gemini in parallel across isolated worktrees.
Code editor
Where I read and review code and make the final touches.
Planning and review
The AI agent that breaks work into tasks, defines the architecture and reviews every step.
Implementation
The AI agent that turns planned work into code, tests it and prepares it for release.
Research and a second opinion
The model I turn to for research and when I want a different perspective.
Skill library for agents
An open-source collection of skills that brings disciplined habits to agents: brainstorming, planning, test-driven development and code review.

A good beginning starts with a conversation.
