I build scalable SaaS platforms, APIs, and integrations for startups and growing businesses.

I’ve delivered production systems through private contracts and long-term client partnerships, and I’m now bringing that same experience to Upwork.

From MVP to production, I help turn ideas into reliable products including subscription platforms, dashboards, and automation systems that are fast, secure, and built to scale.

• SaaS platforms and MVPs

• Subscription systems and billing (Stripe, PayPal and other payment gateways)

• REST APIs and backend services

• API integrations (CRMs, payments, third-party systems)

• Custom dashboards and admin panels

• Workflow automation and internal tools

Tech Stack

Frontend: React, Next.js, TypeScript

Backend: Laravel, Node.js

Typical Work

If you're building a SaaS product or need reliable API integrations, I’m ready to help you move fast and build it right.
