SeatechWorld

Seatech World · 2026

Full-stack engineer

SeaTech World needed a software-house presence that communicates a broad services catalog — custom systems, websites, landing pages, and e-commerce — and converts visitors into leads while signaling AI/ML credibility.

Delivered a responsive marketing site with a services catalog, a CMS-driven blog, and multi-channel lead capture through a contact form, WhatsApp/email links, and a newsletter.

  • Built with Next.js and Tailwind CSS for a fast, responsive site
  • Blog powered by Prismic CMS for non-technical content updates
  • Lead capture via contact form, WhatsApp/email, and newsletter
  • Structured around the company's services, mission, and AI/ML positioning

Quor

Getup · 2025

Sole front-end engineer (greenfield)

Quor sells trust: hardened container images with zero-CVE baselines, SBOMs, and verifiable provenance. Customers needed a console that makes that evidence usable — a growing image catalog to browse, dense package-level security data to inspect, and registry credentials that production pipelines depend on.

Shipped to production with the product's public launch. From empty repo to customers' hands solo: a fully type-safe React SPA where heavy catalog and security datasets stay responsive, and credential flows are designed to be hard to get wrong.

  • Sole front-end engineer — architecture, design system, and implementation from zero to launch
  • Type-safe end to end with React, TypeScript, and the TanStack stack
  • Catalog and image-detail views tuned to stay fast on large security datasets
  • Registry credential and org management designed so CI access is hard to break
