Hi. I'm **Victor**, a full-stack engineer based in South Korea, and this is my first post here.

I've been writing for a while — just in Korean, on my own blog. I'm starting fresh in English on dev.to because most of what I'm working on now (self-hosted LLMs, full-stack infra, building products as a one-person studio) lives in conversations that happen in English, and I'd rather be *in* those conversations than next to them.

So, a short introduction.

I've spent **10+ years** in this work. I started on the frontend, drifted into mobile, and eventually owned the whole stack — frontend, backend, infra, and the decisions that connect them.

Along the way I did **two CTO runs**:

More recently I spent **a year as a remote full-stack contractor for a US SaaS (Wyzly)**, shipping features and running production on Next.js and Supabase across a 14-hour time difference. Remote-across-timezones is its own skill, and that year sharpened it.

I've also built **enterprise AI work** — an LLM agent system for a large organization — and earlier in my career, a stretch of **interactive and kiosk experiences for major Korean enterprises and global brands** at a creative-tech agency. Different worlds (white-glove enterprise vs. scrappy startup), and I'm glad I saw both.

These days I run a **solo studio** and spend most of my energy on two things.

**Building my own products.**

**Running AI infrastructure on my own hardware.**

A lot of my recent work is figuring out how far you can get on a single **RTX 3090** — local model serving, an agent runtime that uses tools and cron and touches real files, KV-cache and quantization tuning, RAG pipelines. It's equal parts engineering and cost discipline, and it's the most fun I've had in years.

I want to write in the open about the stuff I'm actually doing:

I'm also **open to remote contracts and consulting** with global teams — full-stack and AI-engineering work, or CTO-level architecture. But I'm not here to pitch; I'm here to be useful and to learn in public. If something I write helps you, that's the win.

If any of this overlaps with what you're working on — local LLMs, indie products, remote contracting — I'd genuinely like to hear how you're approaching it. Leave a comment, and I'll see you in the next post.
