FastAPI Microservices & High-Throughput APIs
Engineered for data-intensive platforms, fintech processing pipelines, and AI inference backends requiring sub-20ms latency under 10,000+ concurrent requests.
Production System Blueprint
Modular, horizontally scalable infrastructure engineered for resilience, high throughput, and zero single points of failure.
Frontend & Presentation
OpenAPI / Swagger UI client SDK generator, React admin console
Backend & API Services
FastAPI, Python 3.12+, Uvicorn workers, Pydantic V2 compiled in Rust
Database & State Layer
PostgreSQL 16 with asyncpg driver, Redis 7 for caching and rate limiting
Cloud & DevOps Pipeline
Docker, Kubernetes / AWS EKS, Traefik API Gateway, Prometheus + Grafana
Live Production Benchmarks
Every system built by MIHA Technologies is instrumented with rigorous automated latency, throughput, and reliability SLAs.
Non-blocking uvloop event loop with Pydantic V2 native C/Rust parsing.
Asynchronous database connection pooling via asyncpg without ORM overhead.
Rust-powered Pydantic V2 schema serialization.
Optimized multi-stage distroless Docker image.
Architectural Trade-Off Matrix
Deliberate technology selections evaluated on operational complexity, infrastructure cost, and developer velocity.
Eliminates blocking thread pool starvation during concurrent I/O operations, multiplying throughput by 4x per CPU core.
Guarantees bidirectional type safety between backend and frontend while compiling client SDKs automatically.
Prevents cascading failures and isolates network partitions between business domain services.
Sprint Delivery Roadmap

- Production deployment to AWS ECS / Kubernetes cluster
Security & Compliance Standards
Military-grade protection built into the application data flow from day one.
Frequently Asked Questions
Deep technical answers regarding integration, scale, and operational handover.
Why choose FastAPI over Node.js or Go for microservices?
FastAPI with Python 3.12 and Pydantic V2 matches Go's developer throughput while giving direct access to Python's rich ecosystem (NumPy, PyTorch, LangChain, Pandas) without foreign function interface (FFI) overhead.
How does FastAPI handle database connection pooling under high load?
We configure asyncpg connection pools with pre-warmed connections and strict checkout timeouts, recycling idle connections and preventing database CPU saturation.
Can we generate client SDKs for mobile and web teams automatically?
Yes. Every FastAPI microservice we deliver generates an interactive OpenAPI 3.1 schema from which TypeScript, Swift, and Kotlin SDKs can be generated on every build.
