What you get with this Offer
Need your SaaS platform or web app to talk seamlessly with other tools? I build custom web and backend integrations that connect your systems, sync your data, and automate the busywork — so your business runs smoother and faster.
I design and develop secure, scalable backend solutions using Node.js, Express, Python (FastAPI), or PHP (Laravel) with modern frontend frameworks like React or Next.js when needed. Whether you need to connect CRMs, payment gateways, or third-party APIs, I handle everything from planning to deployment.
What I deliver:
Custom API integrations (REST, GraphQL, Webhooks)
Data synchronization between SaaS platforms and databases
Workflow automation to reduce manual tasks
Secure OAuth 2.0 setups for user authentication
Dashboard & Admin panels to manage your data
Scalable cloud deployment (AWS, Firebase, Vercel)
Why me:
- Full-stack experience — front to backend covered
- Fast, clean, and secure API builds
- Transparent communication and quick turnaround
- Focus on scalability and reliability
