You will get Custom Next.js or React Web Application Built for Your Business
Project details
I build custom web applications and SaaS platforms using Next.js and React that are fast, scalable and built to actually support how your business works. Not just a template thrown together but a proper system designed around your goals.
I have built real products that are live and running including an AI powered fintech SaaS platform with multiple portals, a property platform with interactive maps and an employee engagement platform used by teams at Harvard and SAP. So you are working with someone who has shipped real products not just side projects.
What you get when you work with me is clear communication throughout the project, regular updates at every milestone and a clean handover with full source code ownership at the end. No lock in and no disappearing after delivery.
If you need AI features, API integrations or automation built into your application I can handle that as well. I work with OpenAI integrations, n8n, Make and custom workflow automation alongside the core development work.
Whether you are starting from scratch or need someone to take an existing project further I can adapt to where you are and build something that actually works well long term.
