Backend API Development (Go/Python)Angela Purcell
I build production-grade backend APIs that scale. With 5 years of experience (Coinbase, Square 8, Vinovest), I deliver Go or Python APIs that are secure, performant, and fully tested. Whether you need REST or GraphQL, I'll architect your system for reliability and speed. Perfect for early-stage startups and companies needing core backend infrastructure fast.
What's included
Fully Functional Production API
A production-ready REST or GraphQL API built in Go or Python, fully tested with unit and integration test coverage (75%+), adhering to OWASP security standards, with clean, documented code ready for immediate deployment.
Database Design & Optimization
PostgreSQL database schema design optimized for query performance, proper indexing strategy, and scalability planning. Includes data modeling diagrams and migration scripts for safe deployment.
Docker & Deployment Configuration
Docker containerization with production-ready configuration, docker-compose for local development, environment variable management, and deployment guide for your infrastructure (AWS/GCP/your own).
Comprehensive API Documentation
Complete API documentation including Postman collection, endpoint descriptions, authentication flows, error handling guidelines, and code examples. Plus inline code comments explaining complex logic.
FAQs
Yes! I can build from scratch or integrate into existing systems. If integrating, I'll need access to your repo and a brief technical overview of your current stack.
40 hours over 2-3 weeks depending on complexity. A simple CRUD API might take 2 weeks; a complex system with multiple integrations might take 3-4 weeks.
Yes. All projects include 30 days of free bug fixes and minor adjustments post-delivery. I'm available to answer questions via email/Slack during that period.
PostgreSQL by default (proven, scalable, my specialty). Happy to discuss alternatives (MongoDB, etc.) if your use case demands it.
I provide Docker setup and deployment guides. I can also help configure AWS/GCP if needed, or you can deploy using your preferred infrastructure.
