[ Sound familiar? ]
You know you need to go online — you just don't know where to start.
Most businesses stall not on the idea, but on execution.
01
Hiring engineers is hard
Hiring is expensive and slow. With agencies, it's hard to tell who actually delivers.
02
Handed it off, but let down?
Got a deliverable that just wasn't it? We rebuild until you're genuinely happy with it.
03
No online sales channel
Offline alone caps your growth. Without a storefront that works 24/7, you miss customers who would have bought.
04
AI feels out of reach
You want to automate repetitive work with AI, but no one will design how and what to automate.
[ Services ]
As much as you need — owned end to end.
Strategy, design, development, launch and growth in one team. No need to split work across vendors.

Founder
Daehun Lee (Danny)
Founder · Engineer
I spent 3.5 years as a frontend engineer and PM at TWIP (creator platform) and SWING (mobility) — validating data integrity on a $15M-revenue business and lifting paid conversion from 50% to 75%. I then went freelance, contributing to products for companies like T1 and Gelato Pique.
From a student's tiny assignment and a personal-branding landing page to the demanding requirements of B2B companies — I've built across every field and scale. Whatever your stage, don't hesitate to reach out.

[ FAQ ]
Good questions.
Anything not here, we'll answer right away in the consult.
How long does it take?
Landing pages in 48–72 hours, business websites in 1–2 weeks, and web app / AI projects in 2–6 weeks depending on scope. You'll get exact dates in the consult.
How is pricing decided?
Landing pages start at $500 and scale with scope. We give a fixed quote before kickoff, so costs don't grow mid-project.
How many revisions are included?
Two revision rounds before launch are included. Changes afterward are covered by maintenance or a monthly retainer.
What do you build with?
Next.js and TypeScript by default, deployed on Vercel, with Claude and OpenAI for AI. A stack that's fast, ranks well, and stays easy to maintain.
Can you build English / global sites?
Yes — multilingual sites and overseas payments (Stripe) included. This very site supports both Korean and English.
Do you handle ops and maintenance?
Yes, via a monthly retainer covering operations, improvements, SEO and AI automation — used as flexibly as you need.
How does payment work?
Free consult → fixed quote → contract. Typically 50% upfront and 50% at launch. Tax invoices available.
