About me
I'm someone who values clarity, depth, and intention in the way ideas are expressed and built. I'm naturally curious and tend to question surface-level answers, not to challenge for the sake of it, but to truly understand how things work and why they matter. I care about quality and coherence, and I'm most engaged when I can refine, improve, and align ideas until they accurately reflect their purpose.

Pixel-perfect, accessible interfaces with React and TypeScript. Performance-first from the start, built to last in production.

Tools and workflow
WhatsApp booking chatbot for ski rental shops
Mogul lets ski rental customers book equipment through a guided WhatsApp conversation — no app, no account needed. A multi-tenant Node.js backend drives a 12-step booking state machine and pushes confirmed reservations straight into the shop's Easyrent system via SOAP and REST, with webhook signature verification, message deduplication, retries, and a durable queue on PostgreSQL.
AI travel planner that turns trip ideas into day-by-day itineraries — built with Next.js and Claude AI, with Clerk auth, Drizzle ORM on Postgres, and Stripe payments.
A SvelteKit + TypeScript assessment that transforms natural language prompts into interactive architecture diagrams using AI-generated JSON schema and a responsive visual renderer.
Full e-commerce with product catalog, cart, and user auth — built end-to-end with React, Express.js, and PostgreSQL.
