Description

I design and build scalable SaaS platforms from scratch.

I specialize in multi-tenant architectures, AI-powered systems and production-ready MVP development. My focus is not just writing code — it’s designing systems that are secure, maintainable and built to scale from day one.

Founder & technical lead behind:

• Clientum – ERP SaaS platform with invoicing, accounting modules and automation

• Zitio App – Multi-tenant booking & business management platform

• ORUS CRM – AI-driven sales automation system with sequences and outbound engine

• Custom AI agents and automation systems for startups and service businesses

My expertise includes:

• SaaS architecture (multi-tenant, RBAC, audit logs)

• Next.js / React production systems

• Supabase & PostgreSQL (advanced schema design)

• AI integrations (LLM workflows, automation engines, autonomous agents)

• Secure backend design & infrastructure planning

• MVP definition and technical roadmap strategy

I work directly with founders and companies that need a technical partner — not just a developer.

If you’re building a serious product and need someone who understands architecture, scalability and product vision, let’s talk.
