I build LLM systems that are tool-grounded, cost-aware, and safe: multi-agent orchestration, MCP servers, anti-hallucination citation grounding, and local-GPU voice/vision pipelines. 我构建工具落地、成本可控、安全可信的 LLM 系统：多 agent 编排、MCP 服务、反幻觉引用约束，以及本地 GPU 语音/视觉流水线。

Experience经历
My titles say marketing and strategy; my output is production software. Here's where the building happened.头衔写着营销与战略，产出却是生产级软件。下面是这些"构建"发生的地方。
Designed and built Salon OS, an edge-native multi-store ERP/POS for the group's 17-store chain (POS, payroll with CPF/SDL/levy, audit), and am productizing it as a SaaS for the wider salon industry.为集团 17 店连锁设计并构建了Salon OS——边缘原生多店 ERP/POS（POS、含 CPF/SDL/外劳税的薪资、审计），并正将其产品化为面向同行的 SaaS。
Founded a Singapore study-abroad agency and built its admissions CRM end-to-end — a full sales-to-finance pipeline on Cloudflare (RBAC, finance/payroll, OCR, audit), live at app.maplesgedu.com.创办新加坡留学中介，并端到端构建其招生 CRM——Cloudflare 上完整的销售到财务链路（RBAC、财务/薪资、OCR、审计），已上线 app.maplesgedu.com。
Ran marketing, and built the company's multilingual website plus a hub of 24 internal tools — where self-taught coding turned into shipping real software.负责市场，并构建了公司多语网站及 24 个内部工具的工具台——自学编程在这里变成了真正交付软件。
Marketing specialist roles across property and consulting — campaigns, content, and the growth-side instincts that still shape how I build product.地产与咨询领域的营销专员——活动、内容，以及至今仍影响我做产品方式的增长直觉。
About关于
I'm Leonard Chow (Chow Yi Ding), based in Singapore. I came up through digital marketing — but I kept hitting the wall where an idea needed software that didn't exist yet, so I taught myself to build it.我是 Leonard Chow（周毅鼎），在新加坡。我从数字营销起步——但总撞到同一堵墙：一个想法需要还不存在的软件，于是我自学把它造出来。
Now I take products from blank repo to live production on a pure serverless edge stack (Cloudflare Workers + Hono, Next.js / Vue, D1/KV/R2/Queues). Several replace legacy vendor software for real Singapore operators — a multi-store salon ERP/POS, a study-abroad admissions CRM, a salon SaaS with native SwiftUI clients. I care about the unglamorous parts: money-as-integer-cents, append-only audit, RBAC, and Singapore statutory compliance (CPF, SDL, GST, PDPA).如今我用纯 serverless 边缘技术栈（Cloudflare Workers + Hono、Next.js / Vue、D1/KV/R2/Queues）把产品从空仓库做到生产。其中几套替换了新加坡真实商户的老旧厂商软件——多店美业 ERP/POS、留学招生 CRM、含原生 SwiftUI 端的美业 SaaS。我在意那些不光鲜的细节：金额按整数分、只追加审计、RBAC，以及新加坡法定合规（CPF、SDL、GST、PDPA）。
The other half of my work is AI and agent engineering: a contract-driven multi-agent orchestrator, an LLM sales agent with strict source-citation grounding, real-time human + LLM co-editing of a 3D scene over MCP, and a Chinese-English voice framework on local GPU. I lean on orchestrated AI coding agents to ship at a scale that's unusual for a solo developer — and I treat correctness as a deliverable, including dual-engine pre-launch security audits.我的另一半工作是 AI 与 agent 工程：合约驱动的多 agent 编排器、带严格来源引用约束的 LLM 销售 agent、人与 LLM 通过 MCP 实时共编 3D 场景、本地 GPU 上的中英语音框架。我借助编排的 AI 编码 agent，以个人开发者少见的规模交付——并把"正确性"当成交付物，包括双引擎上线前安全审计。
