As a Top Rated Plus freelancer with 15+ years of software engineering experience, 17,000+ hours worked, and 300+ successful projects on Upwork, I have helped founders launch AI startups, build scalable SaaS platforms, automate business operations, and modernize legacy applications.

• Next.js, React & TypeScript
• Node.js, Express.js & REST APIs

• AWS, Docker, CI/CD & cloud deployment
• Stripe, authentication & third-party API integrations

I can help you build:

✓ AI SaaS MVPs

I work closely with founders, startups, and product teams from idea validation to production deployment. Whether you need to build an MVP, add AI capabilities to an existing product, or scale your SaaS platform, I focus on delivering solutions that are reliable, maintainable, and built for real business growth.

My approach is simple: understand the business problem first, design a scalable architecture, write clean production-quality code, and communicate clearly throughout the project. My goal is to become a long-term technology partner who helps clients build successful AI products—not just complete development tasks.
