Sin-Kang (강신)

Founder & CEO of DevsLab — a SaaS development studio in Seoul. I ship production SaaS first, then open-source the parts worth sharing.

Now building: AskLinq — an AI chat that answers visitors' questions about your company, distributed QR-first. Live in production on Cloudflare Workers + PostgreSQL/pgvector.

Open source

All of it lives at the devslab open-source hub — live demos, docs, and install links in one place.

  • editor-ruler npm — Word-style ruler for web rich-text editors: margin/indent drag handles, guides with snapping, table column markers. Froala · Tiptap · CKEditor 5 adapters.
  • ssrf-guard Maven Central · ssrf-guard-js npm — SSRF defense for the JVM and JS/edge runtimes, including URL guards for LLM-agent tool calls.
  • easy-paging-spring-boot-starter Maven Central — annotation-driven offset & keyset pagination for Spring Boot.
  • api-log Maven Central — event-driven API logging into PostgreSQL JSONB.
  • numkey npm · kokey npm · vue-date-rail npm — TypeScript input & UI libraries born from production forms.

Outside my own org, I contribute to TamboUI — the Java library for modern terminal user interfaces.

Stack

Java · Spring Boot · TypeScript · Node.js · Vue · Next.js · Cloudflare Workers · PostgreSQL · Redis · AWS — plus LLM/RAG/agent integration in everything we ship lately.
