Core Expertise

01

Frontend Architecture

Scalable structures built for long-term evolution. Vue.js, Next.js and TypeScript with patterns that sustain growth without breaking.

02

Design Systems

Component libraries that align product and engineering. Consistency, speed and a shared language between design and code.

03

Performance Engineering

Optimized experiences with measurable impact. Every millisecond of LCP is a conscious decision guided by real data.

04

Product Thinking

Technical decisions guided by business strategy. I think about the user and the market before writing the first line of code.

05

AI-Augmented Engineering

Spec-driven development, structured prompts and human review at every step. AI accelerates delivery without creating tech debt — because speed without control is just rework in disguise.

SaaS · Storefront and admin for real estate agencies

useimob

Founder & Full Stack·2026

Challenge

Small agencies and independent brokers sell on Instagram and have no catalog of their own. useimob ships the storefront on the client's own domain, the property admin and leads arriving over WhatsApp — multi-tenant, with per-client isolation in the database and server rendering at the Cloudflare edge.

I deliver solutions with context, ownership, and results.
