  • Sole FS contributor in a 3-person tech team β€” owned end-to-end delivery (UI β†’ API β†’ Admin β†’ release) across 2 platforms generating 85M+ requests/month, ~12,000 products, and 20+ landing pages.
  • Shipped 20+ features/year across both platforms: Flash Sale, Buy-Together, Trade-In Service, Warranty, Authentication, Custom Listings β€” handling FE, BE APIs, admin settings, and production release.
  • Designed and maintained RESTful APIs (Node.js / NestJS): pricing tables, content SEO, trade-in, product search β€” without breaking existing contracts. Built Admin Dashboard modules covering promotions, orders, QnA, schema config, and pricing CRUD.
  • Integrated 5 payment gateways (HomeCredit, MiraeAsset, Kredivo, Homepaylater, Epay) with AES payload encryption for PCI compliance; integrated Hotjar, Filum chat (v1 & v2), and SheerId.
  • Optimised Core Web Vitals across all page types β€” average PageSpeed score improved from 66 β†’ 80+ (+11 pts); Trade-In page +18 pts. Implemented server-level HTML caching to improve SEO crawlability.
  • Led Next.js 13 β†’ 16 migration (Page Router β†’ App Router): restructured routing, rewrote data-fetching, upgraded all libraries, overhauled TypeScript config, resolved multi-stage Dockerfile build failures.
  • Architected API security layer: AES encrypt/decrypt moved to server-side API Routes (secrets off client); built BE-as-Gateway proxy routing all Specs API calls through BE β€” eliminating direct endpoint exposure.
  • Deployed n8n automation platform for the Optimize team on VPS (Docker Compose + Nginx + SSL); supported cross-team API integration, Zalo OA webhook setup, and domain configuration.
