Experience

Full-Stack Engineer, Vioo Company Limited, May 2022 – Present

Primary engineer for concurrent client products — design through cloud deployment, partnering with stakeholders to scope UX and ship production releases.

  • Shipped and maintained 15+ production React / React Native apps end-to-end, including high-fidelity Figma design and shared design systems.
  • Replaced legacy WordPress with headless CMS (Strapi / Sanity) and search (Meilisearch / Algolia): cut load time by 80%, search latency by 90%, and hit PageSpeed Insights >90.
  • Shipped production AI agents (workflows, memory, tool calls, observability) with Mastra, AI SDK, and Langchain, including composable chat and tool-invocation UIs.
  • Established a shared Radix / Tailwind component and hook library with Storybook, Fumadocs, and MDX docs, reused across client apps for consistent UI and faster delivery.
  • Built typed APIs with Hono, Drizzle, OpenAPI, and tRPC on AWS Lambda / API Gateway, backed by Postgres and DynamoDB, with Scalar API docs.
  • Adopted SST for app deployment and infra, cutting build and deploy time by 50%+.
  • Led frontend code and performance reviews (composable React patterns, lazy-loaded heavy UI) and added Cypress E2E coverage for critical flows.
  • Delivered custom Next.js storefronts on Shopify’s headless GraphQL API; advanced Framer Motion / D3 motion and charting where product UX required it.

Selected Projects

Multi-Channel Agentic Platform, Apr 2026 – Present

Client-facing agent platform for durable, multi-channel assistants (web + Discord) with production reliability and quality controls.

  • Led durable streaming so clients can disconnect and resume mid-run without losing progress.
  • Built workflow, memory, scheduling, and workspace primitives on Mastra and AI SDK: pause/resume, retries, file storage, sandboxed tools, and skills.
  • Shipped end-to-end RAG: ingest/parse, chunking, and Pinecone retrieval with query/rerank (and graph query where needed).
  • Ran Hono + Better Auth on ECS, with Postgres for core data and S3 for files.
  • Added run/tool traces and cost/latency metrics in ClickHouse, plus scored eval suites (golden prompts + LLM-as-judge) to catch quality regressions before release.
  • Shipped a TipTap @mention file-tagging component for attaching workspace files into agent prompts.

High-Performance Marketing Site, Nov 2025

Lead engineer for a content + search marketing site — performance, CMS, and publish workflow owned end-to-end.

  • Next.js + Strapi + Meilisearch content site with LCP < 0.5s, CLS < 0.1, and PageSpeed Insights >90.
  • Hybrid ISR: main pages and the latest 100 articles pre-rendered at build; remaining pages on demand; tag-based revalidation via Strapi webhooks so publishes go live without full rebuilds.
  • Built a custom Strapi plugin for generative AI content creation with AI SDK.
  • Accessibility and SEO as ship criteria: semantic structure, keyboard-safe nav/forms, Lighthouse + axe checks; metadata/OG, canonicals, sitemap, robots.txt, and Article JSON-LD from CMS.
  • Turborepo on AWS ECS with SST, API Gateway, and S3 media; interactive UI with TanStack Query prefetch/hydration and TanStack Form + Zod mutations.

React Native Membership Platform, Apr 2024

  • Led Figma design and frontend app development for a catering-brand membership app (digital card, points, offers); shipped iOS and Android to the App Store and Play Store.
  • Also responsible for backend maintenance: Express API and a Next.js admin panel.
  • Integrated typed REST clients from OpenAPI/Swagger; Firebase Cloud Messaging for push notifications and deep-linked campaigns (promos and milestones).
  • Maintained >99.5% crash-free sessions post-launch (Sentry).
  • Cut list jank with FlashList; kept inactive tabs cheap via react-native-screens freeze and deferred mounts; reserved Reanimated for native-thread transitions.
  • Shortened image loading in feeds by caching remote images and avoiding full-resolution assets in long lists.

Other Work

Also shipped a health & wellness RAG agent (Next.js, Langchain, Shopify API), restaurant loyalty and membership apps (React Native), a photobooth event app (React Native, Skia, Next.js), a content platform with CMS (Next.js, Strapi), campaign/event and e-commerce sites (Next.js, Sanity / Strapi, Shopify GraphQL), an RBAC resource system (Next.js), a homebound elderly care app (Flutter), and a book ordering system (Laravel + React).
