Backend Engineering Services
I build backends that scale, from MVP to millions of users.
With 10+ years of production experience, I’ve architected and built systems for startups and enterprises across fintech, legaltech, healthtech, e-commerce, and SaaS. My backends have processed millions of transactions, served real-time data to thousands of concurrent users, and powered AI systems at scale.

Frequently Asked Questions
How much does backend development cost?
Backend development costs $100-150/hour for senior expertise. Simple APIs start at $15,000-30,000. Full SaaS backends range from $50,000-150,000+. I offer competitive rates with prepaid hour bundles starting at $45/hr effective.
What programming language should I use for my backend?
It depends on your use case: Python (FastAPI/Django) for AI/ML integration, rapid development, data-heavy apps. Node.js for real-time features, JavaScript teams. Java/Spring for enterprise systems, high-throughput. I help you choose the right stack.
Can you work with my existing codebase?
Yes. I regularly join existing projects, refactoring, adding features, improving performance. I start with a codebase audit to understand architecture before making changes.
Do you handle DevOps and deployment?
Yes. I provide end-to-end service including Docker containerization, CI/CD pipelines, cloud deployment (AWS/GCP), monitoring, and infrastructure as code. See Cloud & DevOps Services.
