What I Build

Enterprise Portals

Multi-tenant applications, admin dashboards, client portals with roles and permissions. Built for organizations that need reliability and security at scale.

SaaS Products

From MVP to production-ready. Subscription management, billing integration, user management, analytics. I help you validate your idea fast and scale when it works.

Custom Web Applications

Internal tools, CRM systems, project management platforms, specific workflow automation. Any business logic, any complexity.

PWA Applications

Web applications with a native mobile feel. Offline mode, push notifications, installable on devices. One codebase, all platforms.

FAQ
A website primarily displays information — a corporate site, a blog, a landing page. A web application handles complex logic — user accounts, dashboards, data processing, real-time features. I build both, but web applications are where my architecture expertise really shines.
An MVP takes 4-8 weeks. A full-featured application takes 8-16 weeks. Complex enterprise systems with integrations can take 3-6 months. I always provide a detailed timeline before we start.
Yes, and I particularly enjoy it. I help you identify the smallest functional core of your idea, build it fast, and get it in front of real users. If it validates, we scale. If not, you've invested weeks instead of months.
My primary stack is Next.js with TypeScript for frontends and Laravel or Node.js for backends, with PostgreSQL as the database. This combination offers excellent developer experience, performance, and scalability. I choose the specific tools based on your project's requirements.
Yes. I regularly take over codebases from other developers or agencies. I start with a technical audit — code quality, architecture, security, performance — and then propose either improvements or a strategic rebuild.
