Scalable Backend Development for SaaS & Web AppsSiddiq Tashfeen
I build secure, scalable, and maintainable backend systems for SaaS products, web applications, and custom business platforms.
As a Backend Engineer, I focus on designing reliable APIs, clean server-side architecture, database structures, authentication systems, and third-party integrations that support long-term product growth.
Whether you need a backend from scratch, API development, database design, or performance improvements, I build systems that are fast, stable, and ready for production.
What I can help you with:
• Custom backend development
• REST API design and development
• Node.js, Express, Python, and FastAPI
• Database design with PostgreSQL and MongoDB
• Authentication and role-based access control
• Third-party API integrations
• Performance optimization and backend refactoring
• Cloud deployment and production-ready architecture
I prioritize scalability, code quality, and long-term maintainability so your product has a strong technical foundation.
