Backend Engineering That Scales With Your Product
Modern products live and die by the strength of their backend. Slow APIs, poor architecture, and tightly coupled systems quickly become blockers for growth.
At PySquad, we specialize in Django and FastAPI development focused on performance, scalability, and long-term maintainability. We do not just build APIs that work today. We engineer backend systems that continue to perform as users, data, and complexity grow.
Why Django and FastAPI Are at the Core of Our Work
We choose technology based on real-world needs, not trends.
Django for Stability and Business Logic
Django is ideal for complex domains, data-heavy platforms, admin systems, and long-term products where reliability matters.
FastAPI for Speed and Performance
FastAPI allows us to build blazing-fast APIs, microservices, and async systems that handle high traffic with lower infrastructure costs.
By combining Django and FastAPI where appropriate, we design systems that balance speed, structure, and scalability.
What Makes PySquad Different in Backend Development
Architecture First Approach
Before coding, we design clean service boundaries, data models, and API contracts. This prevents technical debt later.
Production-Ready From Day One
Authentication, authorization, logging, monitoring, and error handling are built in, not added as afterthoughts.
Performance as a Core Requirement
We optimize queries, caching, async workflows, and API response times from the start.
Clear Ownership and Accountability
You work directly with senior engineers who own the system, not hand-offs between disconnected teams.
