01 / About

Building production software that scales.

With 2.5 years of hands-on experience, I specialize in building production-grade SaaS applications using Next.js (App Router), Supabase, Tailwind CSS, and TanStack Query.

I focus on strong server/client architectural separation, delivering measurable performance improvements — including a 30% gain through strategic query optimization and partial prerendering techniques.

Every project I ship is deployed on Vercel with CI-ready code, clean component architecture, and a relentless focus on user experience.

Ethileo

A two-sided event-planning platform built as an npm-workspaces monorepo — a consumer wedding planner and a vendor marketplace sharing one database and design system. Centered on three custom canvas editors for designing invitations, wedding websites, and seating charts.

  • Integrated Stripe for gift checkout, refunds, and PDF invoice generation
  • Built file uploads to Backblaze B2 (S3-compatible) with presigned URLs and sharp image processing
  • Implemented role-based access (admin / professional / user) with feature-gating, trial limits, and a pro↔client portal
