[ 03 ]Featured Work

Sixteen products, one through-line: ship with craft.

Selected work at Burning Bros & SGOD, freelance client engagements, and solo-shipped personal products — spanning B2B2C commerce, high-CCU systems, gamified marketplaces, and privacy-first apps.

01Gamified Commerce · High-CCU Scale03/2026 — Present

Play In The Box

Frontend Engineer — Performance & Reliability · Burning Bros · Korea

Gamified e-commerce platform for Korean fandom merch — gacha box-opening, raffles, and campaign drops including The First Fan × G-Dragon — that has to survive its own launch-day traffic spikes. Diagnosed and fixed a ~30k-CCU production outage (p95 latency 38s, 50k/min 5xx) by eliminating cache-stampede and sticky-404 bugs and capping unbounded HTTP socket growth, then authored the edge-caching + ECS auto-scaling architecture and built an in-region k6/EKS load-testing rig to validate fixes directly against production.

Presentation-slide template marketplace and design-agency site — browse, buy, and download PowerPoint/Keynote decks through a VietQR + SePay webhook payment flow, alongside a blog and a bespoke design-service funnel. Built fullstack across three repos: a NestJS + Hasura backend with atomic webhook-driven payment confirmation and presigned MinIO downloads, a Next.js 15 storefront, and an Ant Design admin panel.

10Media Production · BPM07/2025 — Present

Antue Media BPM

Fullstack Engineer (solo) · Client project

Business-process-management platform for a media production company — orders flow through multi-format content creation (image, video, 3D), QC review, and automated publishing to an external stock-media marketplace, with KPI dashboards and role-gated permissions across editorial and design teams. Solo-built and documented end-to-end over a year: a Hasura-first hybrid backend, Redis/BullMQ pipelines for multi-gigabyte video uploads, and a self-authored architecture doc that honestly catalogs its own production trade-offs.

11Content Ops · Workflow06/2025 — 05/2026

Channel Ops Workflow

Lead Frontend Engineer · Client project

Content and channel-operations workflow tool for a media team — submissions move through a review pipeline (pending → revision → approved → published) with per-channel roles, threaded comments, and a full audit trail. Notifications are computed entirely by Postgres trigger functions reacting to row changes, decoupled from the API layer. Led and built the majority of the React admin panel — real-time GraphQL subscriptions over a Hasura + NestJS backend.

Uranus

Frontend Engineer · Client project

Print-job management system for a teaching center — staff upload class documents, queue print jobs with paper/duplex options, and a polling agent on the print-shop machine drives the physical printer via presigned MinIO downloads. Built the admin dashboard end-to-end and a standalone microservice that page-counts DOCX/PPTX files to drive per-class print billing.

Wavesgroup

Fullstack Engineer — Marketing & Livestream · Client project

Social-growth ecosystem — an SMM order engine proxying view/subscribe/comment boosts to a third-party provider, and a 24/7 livestream platform that drives ffmpeg-encoded loops to YouTube with lease-based failover if an encoder pod dies. Owned the marketing service and livestream/encoder stack solo: Kubernetes autoscaling via KEDA (0→50 pods on demand), a hexagonal ports/adapters architecture with an outbox pattern, and resumable multipart uploads up to 10GB — all behind a shared Keycloak SSO layer.

Knotos

Founder & Fullstack Engineer (solo) · Personal project

An "anti-social-media" chat app built for one relationship at a time — day-streaks, shared-memory resurfacing, always-on WebRTC voice rooms, and Gemini-powered daily questions, wrapped around an opt-in E2EE (X25519 + AES-GCM) messaging core. Solo-built polyglot monorepo: NestJS + MongoDB + Redis backend, a native SwiftUI client, an Ant Design admin portal, and a published MCP server that lets Claude/ChatGPT draft and publish the app's own blog content.

15Disguised Privacy Vault07/2026 — Present

Toolbox

Fullstack Engineer (solo) · Personal project

A fully working calculator that unlocks into an encrypted personal vault on the right passcode — photos, files, passwords, and a private browser, guarded by Argon2id + AES-256-GCM with a DEK-wrap key hierarchy so passcode changes never require re-encrypting the vault. Ships decoy-vault, intruder-selfie, and fake-crash countermeasures alongside a RevenueCat-powered subscription model.

16Local-first Bookmarking07/2026 — Present

Linkeeper

Fullstack Engineer (solo) · Personal project

A local-first bookmark manager for the links worth keeping — save straight from TikTok/Instagram/YouTube's share sheet without opening the app, auto-tagged by platform, readable fully offline. SQLite (WatermelonDB) is the sole source of truth; Supabase is a strictly optional layer for cross-device sync, public collection sharing, and account deletion — the app works completely with zero account.
