Backend Development Services
End-to-end backend development services and API development services for SaaS, ecommerce, and AI products. Custom backend development in Python with Django, FastAPI, and Flask — deployed on AWS with monitoring, CI/CD, and full documentation.
What you get with custom backend development
A senior Python engineer who has shipped backends for SaaS, AI, and ecommerce clients in the USA, UK, Germany, and Australia. I take ownership of architecture, code quality, deployment, and the runbook your future team will live in.
Capabilities
REST API development
Clean endpoint design, JWT / OAuth2 auth, rate limiting, OpenAPI docs, versioning, and end-to-end tests.
SaaS backends
Multi-tenancy, subscription billing (Stripe), team management, audit logs, scalable from day one.
Third-party integrations
OAuth2 flows, webhook handling with retries and idempotency, dependable sync with HubSpot / Close / Salesforce / Stripe / Zoom.
Async & background jobs
Celery + Redis for report generation, file conversion, long-running AI inference, and bulk data ops.
Database design
PostgreSQL schemas built for scale, indexes, query plans, migrations, and read-replica setup when you need it.
AWS deployment
Docker → ECR → ECS / Lambda, API Gateway, S3, CloudWatch, IAM-scoped credentials, and CI/CD on GitHub Actions.
The framework choice
Django + DRF for products that need an admin, ORM, and "batteries-included" auth out of the box. The fastest way to a production REST API for most B2B SaaS.
FastAPI for high-performance async APIs, model-serving endpoints, microservices, and anywhere you want native OpenAPI generation and Pydantic validation.
Flask for lightweight utilities, internal tools, and simple webhook receivers.

How an engagement runs
- Day 0: 30-min call to scope. Written quote and timeline within 4 hours.
- Week 1: Repo setup, CI, base architecture, first auth + 2-3 endpoints in your staging env.
- Weeks 2-N: Iterative builds with weekly demos and async standups.
- Final week: Production deploy, runbook, knowledge-transfer Loom, 30-day bug-fix window.
Pricing
- API integration / single endpoint set: $400 – $1,500 fixed-price.
- SaaS backend MVP: $4,000 – $12,000 (3-6 weeks).
- Replatform / refactor: $5,000 – $20,000 depending on scope.
- Hourly: $60 – $120 / hr depending on engagement length.
- Monthly retainer: $1,500 – $4,500 / month.
Frequently asked questions
What do backend development services include?
Backend development services cover the architecture, REST APIs, database design, authentication, integrations, async tasks, deployment, and monitoring of your server-side stack. I build production backends in Django + DRF and FastAPI, deployed on AWS with Docker and CI/CD.
What are API development services?
API development services are end-to-end design and build of REST (or GraphQL) APIs your frontend, mobile app, or third parties consume. Includes endpoint design, OpenAPI / Swagger docs, auth (JWT / OAuth2), rate limiting, versioning, error handling, and testing.
When do I need custom backend development vs. a SaaS?
Custom backend development is right when you have unique business logic, sensitive data, performance requirements a SaaS cannot meet, or a roadmap that needs full control. If you are gluing together 5+ SaaS tools and paying $1k+ / month, custom backend development almost always pays for itself in 12-18 months.
Which Python framework do you use?
I work with Django + DRF for full-featured products that need admin, ORM, and authentication out of the box; FastAPI for high-performance async APIs and microservices; and Flask for lightweight utilities. I will recommend the right one based on your team and roadmap — not based on what I prefer.
Do you handle deployment and DevOps?
Yes. I containerize with Docker, deploy to AWS (EC2 / ECS, Lambda, S3, API Gateway, RDS), configure CI/CD pipelines, set up CloudWatch + Sentry alerting, and document the operational runbook so your team can take over.
Do you write tests?
Yes. Pytest with fixtures and factories, integration tests against a real test database, and at least smoke tests for every API endpoint. CI runs the suite on every PR.
