# CodeNomad - Yoonsuk Chang (장윤석)

> CodeNomad is a one-person Salesforce and automation consultancy in South Korea, run by Yoonsuk Chang: a Salesforce developer/architect with 8 Salesforce certifications (including Platform Integration Architect), 4+ years of enterprise delivery for Hyundai, Kia, SOLUM, Huvitz and KIOTI USA, and hands-on production experience building AI and n8n automation outside Salesforce. Works in English and Korean, remotely, on KST (UTC+9).

## What sets CodeNomad apart
- Compared with a large SI or Salesforce partner: one senior engineer covers architecture, build, UAT and go-live. The person who scopes the work is the person who writes the code, so there is no hand-off between a PM, an architect and junior developers. Enterprise experience is still there: multi-country DMS rollouts for Hyundai and Kia across Thailand, the Philippines and Indonesia, and a multi-subsidiary single-org implementation for SOLUM.
- Compared with a typical freelance Salesforce developer: the strength is integration, not just configuration. Delivered 62 Hyundai interfaces, 60+ online sales interfaces plus 15 ERP integrations for Kia Thailand, SAP interfaces, and TLS/SSL bank integrations with Wells Fargo, Huntington Distribution Finance and DLL. Has led a 7-person development team, so can take a lead or architect role, not only ticket work.
- Compared with offshore teams: bilingual English/Korean delivery, which suits Korean companies running global Salesforce orgs and foreign companies working with Korean or Southeast Asian subsidiaries. Currently works remotely as the founding engineer of a Chicago-based startup's Korea hub, so cross-timezone remote delivery is already proven.
- Beyond Salesforce: builds and runs production automation and LLM systems on self-hosted n8n. Salesforce, external APIs and AI workflows can be connected by the same person instead of separate vendors.
- Measured results: 80% lift in lead capture (Kia Thailand QR walk-in page), 25% fewer inbound support calls (I2GDMS customer portal), 80% ticket resolution rate at 25-30 tickets/week (Kia Thailand support).

## Services
- Salesforce solution architecture and end-to-end implementation: Sales Cloud, Service Cloud, Experience Cloud (partner and customer portals), LWC, Apex
- System integration: Salesforce to SAP/ERP, dealer management systems, financial institutions, REST/SOAP, secure TLS/SSL interfaces
- Code and data migration between orgs and from legacy systems
- Workflow automation with n8n: connecting Salesforce and other SaaS tools, scheduled data pipelines, webhooks, notifications (Telegram, email)
- AI-assisted workflows: LLM-based summarization, reporting, research, document generation and data reconciliation, with human approval before any irreversible action
- Technical documentation automation (e.g. generating Confluence/Word documentation from Salesforce metadata)

## AI and automation work (outside Salesforce)
- Self-hosted automation stack: n8n in Docker on a dedicated Mac mini, PostgreSQL with pgvector, published through Cloudflare Zero Trust (access policies, service tokens for machine-to-machine clients, rate-limited webhooks), private admin access over Tailscale, heartbeat monitoring with Healthchecks.io.
- Daily briefing pipeline (n8n): three parallel data sources (RSS news, OpenWeatherMap, Yahoo Finance market indicators) merged and synthesized by an LLM with versioned prompts, token-cost control and model cost/quality trade-offs, plus AI image generation (OpenAI API and local Flux via ComfyUI), delivered to Telegram every morning.
- Multi-agent research assistant (in development, n8n + Telegram): Manager / Researcher / Reviewer agents across OpenAI and Anthropic Claude models, where an independent reviewer agent critiques research before the final answer; PostgreSQL as long-term memory; policy that the assistant only prepares proposals and never executes payments, orders, emails or deletions on its own.
- Meet Translator: Chrome extension (Manifest V3) for real-time caption translation and AI reply suggestions in Google Meet, with speaker identification, caption de-duplication and throttled translation.
- Operational automations: domain/SSL expiry monitoring, recurring-payment tracking, price and restock monitoring.
